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 rotation of each reel. When the player depresses the start lever after performing a bet operation to start the game, all reels rotate all at once, 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.

  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.

  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 the prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly deviated from the appropriate timing, the symbols constituting the combination corresponding to the prize group stop on the winning line. Pull-in control is performed as described above. 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, the winning of a certain prize group is won by internal lottery, and the timing of the symbols constituting the role corresponding to the winning prize group is aligned on the valid winning line It is necessary to perform a reel stop operation within a predetermined allowable range.

  In such a slot machine, the player is notified of the result of the internal lottery. For example, when a winning result is won, such as a big bonus award, which is carried over to the next game, the reel stop control is changed to display a characteristic symbol combination. . As a characteristic symbol combination, for example, there is a symbol combination (so-called reach) that appears only when a special prize is won. In many cases, the stop control for displaying such a combination of symbols is continuously performed over a plurality of times until the winning special prize is won (for example, Patent Document 1).

JP 2001-218892 A

  However, until the winning special prize is won, such stop control is continuously performed, and characteristic symbol combinations are frequently displayed. As a result, the difference from the normal time increases. Therefore, it is easily known to the player that the special prize has not been carried over.

  Therefore, the present invention provides a slot machine that can give a player a sense of expectation by creating a pseudo situation similar to the situation in which a special prize is won even if the internal lottery is lost. For the purpose.

  Hereinafter, the slot machine of the present invention will be described. 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.

  In the slot machine of the present invention, a prize for lottery of a plurality of reels (R1, R2, R3) displaying a plurality of types of symbols and a prize group which is a group of one or a plurality of roles is selected. A group lottery means (31), a stop control means (31) for controlling each stop operation of the plurality of reels in accordance with a lottery result of the prize group lottery means, and a state where each of the plurality of reels is stopped Depending on whether or not the symbol combination displayed on the predetermined winning line (L1, L2, L3) matches the symbol combination preset as the combination corresponding to the prize group won by the prize group lottery means. A winning determination means (31) for determining whether or not the winning combination is won, and when the winning determination is determined by the winning determination means for a special combination corresponding to a special prize group set in advance among the prize group. Special role A slot in which one game is started by a predetermined operation for starting a game by the player and the next predetermined operation is permitted, and then the one game is finished In the machine, when the lottery result of the prize group lottery means is lost, the stop control means is displayed on the predetermined winning line when the special prize group is won and the special combination is not won. The specific stop control for controlling the stop operation of each of the plurality of reels is performed so that the symbol combination common to at least one of the symbol combinations is displayed on the predetermined pay line, and the specific stop control is performed The success or failure of the transition condition allowing the transition to the specific stop control period in which the state in which the frequency of execution is higher than usual is continued over a plurality of games. When the transition determination means (31) to be determined and the transition determination means determine that the transition condition is satisfied and shift to the specific stop control period, the specific stop control is executed until a predetermined number of times of two or more is reached. Thus, the above-described problem is solved by providing specific stop control period management means (31) for managing the stop control means.

  According to the present invention, when the lottery result of the prize group lottery means losing, the specific stop control for displaying the symbol combination common to the symbol combination displayed when winning the special role and not winning is performed. Is called. This common symbol combination is referred to as a so-called chance item, and is a symbol combination that is displayed both in the case of winning the special role and not winning, and in the case of losing. For this reason, the expectation of winning the special role can be given to the player who encounters the chance. In addition, when a predetermined condition is satisfied, the state where the frequency of execution of the specific stop control that causes the chance to appear is increased to a specific stop control period that continues over a plurality of games. Within the period, chances can appear continuously. Therefore, since a special situation similar to the situation where the winning result is carried over and the winning result is carried over can be created, the player's expectation can be raised.

  In the slot machine of the present invention, a storage means (35) for storing a plurality of stop tables (TBL2) having stop position information as information on the stop positions of each of the plurality of reels; Stop table selection means (31) for selecting a stop table, and determination means (31) for determining whether or not to execute the specific stop control every time the lottery result of the prize group lottery means loses during the specific stop control period. ), And in the plurality of stop tables stored in the storage means, as the stop position information, information (DAT1a) for winning the special role and information for not winning the special role ( DAT1b), and the first stop table (selected by the stop table selection means when the special prize group is won) 21) and the stop position information includes common information (DAT2a) common to information that is not won in the special combination included in the first stop table, and the stop position information is determined according to the determination result of the determination means. And a second stop table (211B) selected by the table selection means, and the stop control means is configured such that the stop position of the second stop table selected by the stop table selection means The specific stop control may be executed so that each of the plurality of reels stops according to the information (claim 2). This form can also solve the problems of the present invention.

  The slot machine of the present invention further comprises execution permission / non-permission specifying means (TBL8A) for specifying, for each game, whether or not to execute the specific stop control until the predetermined number of times equal to or greater than two is reached. Whether or not to execute the specific stop control may be determined with reference to the specified content of the specifying means (claim 3). According to this aspect, whether or not to execute the specific stop control can be freely determined in advance, so that the intention of the designer can be accurately reflected.

In the slot machine of the present invention, the lottery value designating means (TBL6A, TBL6B, TBL6C) for designating the lottery value for defining the probability that the execution of the specific stop control is permitted for each game, and the contents of the lottery value designating means A specific stop control lottery means (31) for lottery of permission for execution of the specific stop control with reference to the determination means, wherein the determination means performs the specific stop control based on a lottery result of the specific stop control lottery means. Whether to execute or not may be determined (claim 4).
In this case, the lottery value designated by the lottery value designation unit may include a first predetermined value and a second predetermined value different from the first predetermined value (Claim 5). According to these forms, since chance can be given to whether or not to execute the specific stop control, it is difficult for the player to understand the intention of the designer. Moreover, one-patterning can be avoided, so players won't get bored.

  In the slot machine of the present invention, stop operation means (7a, 7b) provided corresponding to each of the plurality of reels and generating a stop instruction signal for designating each position of the plurality of reels in accordance with a player's operation. 7c), and the stop control means controls the stop operation of each of the plurality of reels based on the plurality of stop tables and the detection timing of the stop instruction signal, and displays on the plurality of reels. The symbols to be included include specific symbols arranged on each of the plurality of reels at intervals falling within a predetermined range, and the second stop table has any detection timing of the stop instruction signal. However, the stop position is such that a combination of predetermined symbols composed of the specific symbols is always displayed on the predetermined winning line. Distribution is optionally configured (claim 6). According to this aspect, since the chance chance can be surely displayed in the specific stop control period regardless of the timing of the stop operation by the player, the above-described pseudo situation can be surely created.

  In the slot machine of the present invention, there is a re-game prize winning probability that is preset as a game state and one of the prize groups, and that allows the next game to be executed without inserting a game value medium. A gaming state switching means (31) for switching between a replaying high probability state that is higher than the winning probability in the normal state, and a replaying high probability game number management means for managing the number of games in the replaying high probability state. (31), and the transition determination unit determines whether the transition condition is satisfied when the gaming state switching unit switches to the high replay probability state, and the specific stop control period management As the means, the replay high probability game number management means may be used (claim 7). Since the management of the specific stop control period and the management of the number of replay high-probability games can be performed together, it can contribute to the compression of the data capacity.

  In the slot machine of the present invention, the transition condition is set such that a winning corresponding to a predetermined prize group out of the award group or a non-winning of the corresponding combination and winning a predetermined lottery is set. (Claim 8). According to this form, since the player is not aware of the opportunity to switch to the specific stop control period, it is difficult to distinguish the situation where the special result is won and the winning result is carried forward, and the player's expectation is further increased. I can talk.

  Further, as a mode for selecting the stop table, the plurality of stop tables stored in the storage means may include a third winning combination that can win a combination set corresponding to a prize group other than the special prize group. A stop table (231) and a fourth stop table (212) that cannot win any combination are further included, and the first, second, third, and fourth in the storage means The table further includes stop table designating means (TBL4) for designating each storage position of the stop table, wherein the stop table selecting means refers to the storage position designated by the stop table designating means, the first and second In addition, at least one of the third and fourth stop tables may be selected (Claim 9), and the stop table selecting means is preset according to the lottery result of the prize group lottery means. Office And offsetting the reference position of the stop table designating means according to the value of the second stop table, and when the determination means determines that the execution of the specific stop control is permitted, The second stop table may be selected by offsetting to a reference position that designates a storage position.

  In the present invention, the “game value” means a value obtained by the player, and the game value determined by a prize group or a combination includes a dividend, a transition to a high-winning normal game, and a re-game. The “game value medium” is a tangible object made of metal, plastic, etc., which is generally called “coin”, “medal”, “token” etc. In addition to tangible objects such as spherical game balls used in so-called pachinko machines, the concept includes virtual medals that are exchanged and distributed using electronic recording media such as magnetic cards and IC cards. Further, “payout” means a game value medium that is paid out to a player by a prize.

  As described above, according to the present invention, even when the internal lottery is lost, it is possible to increase the player's expectation by creating a pseudo situation similar to the situation where the special prize is won.

<1-1: External configuration of slot machine>
FIG. 1 is a perspective view showing an appearance of the slot machine 1 according to the embodiment of the present invention. The housing of the slot machine 1 includes a main body 2 and a front door 3 attached to the front surface of the main body 2.

  The panel display portion D in the middle stage of the front door 3 is provided with three vertically long display windows 4a, 4b, and 4c. The display windows 4a, 4b, and 4c are formed of a transparent material such as acrylic resin. Further, three winning lines L1 to L5 are provided horizontally and obliquely on the display windows 4a, 4b, and 4c.

  In addition, an auxiliary display unit 20 is provided on the left side of the display window 4a. The auxiliary display unit 20 includes five LEDs corresponding to the pay lines L1 to L5, respectively. When the player inserts medals or performs a bet operation to be described later, the number of pay lines L1 to L5 corresponding to the number of bets becomes valid. In this slot machine 1, the winning line L1 is valid when the number of bets is one, the winning lines L1 to L3 are valid when the number of bets is two, and the winning lines L1 to L1 when the number of bets is three. L5 becomes effective. Each LED constituting the auxiliary display unit 20 is turned on when the corresponding winning line L1 to L5 is valid, and is turned off when the corresponding winning line L1 to L5 is invalid. Thus, the player can know which winning lines L1 to L5 are valid.

  Inside the panel display D, three rows of left, middle and right reels R1, R2 and R3 each having a plurality of types of symbols drawn on the outer peripheral surface thereof are rotatably provided. FIG. 2 shows the structure of the left, middle, and right reels R1, R2, and R3, and FIG. 3 shows the detailed structure of the right reel R3. Each of the reels R1 to R3 has an annular shape, and various symbols are printed on its surface (surface visible from the display windows 4a to 4c). A light shielding film S that shields light is formed on the back surface of the right reel R3 except for a part thereof. In the portion where the light shielding film S is formed, light is not transmitted even if light is irradiated from the back side. On the other hand, the light shielding film S is not formed on each design portion, and the uneven member P for scattering light is formed on the back surface of the right reel R3. In addition, the reel of each design part is white and translucent. In the example shown in FIG. 3, the concavo-convex member P is formed inside the contour portion of the symbol “7”.

  A right reel illumination unit 670 is disposed on the inner peripheral surface side of the right reel R3. The right reel lighting unit 670 includes upper, middle, and lower shades partitioned by walls. A light source 67 is provided in each of the upper, middle, and lower shades. As the light source 67, a cold cathode tube, an LED, or a light bulb can be used.

  Further, a part of the right reel R3 is provided with a light shielding piece 491 protruding from the reel body. When the right reel R3 rotates, the light shielding piece 491 crosses the photocoupler 492. The structure of the left reel R1 and the middle reel R2 and the peripheral configuration thereof are the same as the structure of the right reel R3 and the peripheral configuration thereof described with reference to FIG.

  Returning to FIG. 1, the description will be continued. Below the display windows 4a, 4b, and 4c, there is provided an operation unit OP on which various operation members for a player to execute a game are arranged. The operation unit OP includes a medal slot 5, a start lever 6, left / middle / right reel stop buttons 7a, 7b, 7c as stop operation means, a credit button 8, and a BET button 15.

  The medal slot 5 is provided below the display window 4c so that medals can be inserted. As described above, when one medal is inserted, the winning line L1 is enabled, when two medals are inserted, the winning lines L1 to L3 are enabled, and when three medals are inserted, the winning lines L1 to L5 are enabled. Further, when the player inserts more than 3 medals, the slot machine 1 stores the number of medals of 4 or more as credits.

  The BET button 15 is provided on the lower left side of the display window 4a. The BET button 15 is used for designating the number of medals bet by the player in one game. By operating the BET button 15 by the player, the stored medals can be bet without inserting medals from the medal insertion slot 5. Therefore, the winning lines L1 to L5 are appropriately enabled according to the number of medals designated by operating the BET button 15. The relationship between the number of medals designated by the operation of the BET button 15 and the valid pay lines L1 to L5 is the same as when medals are directly inserted.

  The start lever 6 is provided below the BET button 15. When the player depresses the start lever 6, the reels R1, R2, and R3 start to rotate all at once, and the symbols in the display windows 4a, 4b, and 4c are variably displayed.

  Left, middle and right reel stop buttons 7 a, 7 b and 7 c are provided on the right side of the start lever 6. The left, middle and right reel stop buttons 7a, 7b and 7c are used to stop the three rows of left, middle and right reels R1, R2 and R3 rotating in the display windows 4a, 4b and 4c, respectively.

  On the right side of the reel stop button 7c, a credit button 8 for determining whether or not to store medals in the slot machine 1 is provided. The player can change whether the credit is valid or invalid by operating the credit button 8. In a predetermined case, medals are paid out to the player from the medal payout opening 10 a and stored in the medal tray 10.

<1-2: Role>
FIG. 4 shows an example of symbols displayed on the left / middle / right reels R1, R2, and R3. As shown in this figure, 21 symbols and 7 types of symbols are displayed on each of the reels R1, R2 and R3, and each symbol has a symbol number PN = 1 to 21 along the symbol arrangement order. Assigned.

  In a game by the slot machine 1, when a predetermined combination of symbols is arranged on the pay lines L1 to L5 that are made effective by inserting medals, the number of medals corresponding to the arranged symbols is paid out. In addition, in the following description, it is necessary to indicate that a combination of symbols set in advance as a combination is aligned (displayed) in any of the activated pay lines L1 to L5 in the following description. This is called “winning”. The arrangement (combination) of symbols is broadly divided into “combination” that gives the player a profit (game value) obtained by the game and “no prize”. The role of this embodiment includes the following.

  1) Red 7 role (special role) This role is played with the symbol number PN = 7 or 1 on the left reel R1, the symbol number PN = 9 on the middle reel R2, and the symbol number PN = 9 or 1 on the right reel R3. It is an arrangement of symbols.

  2) White 7 role (special role) This role is a symbol with symbol number PN = 12 on the left reel R1, a symbol with symbol number PN = 11 or 1 on the middle reel R2, and a symbol with symbol number PN = 13 on the right reel R3. It is a line of.

  3) BAR Role This role is a sequence of symbols of symbol number PN = 17 in the left reel R1, symbols of symbol number PN = 14 in the middle reel R2, and symbols of symbol number PN = 18 or 5 in the right reel R3.

  4) The role of the bell The role of the symbol number PN = 20, 15, 10, 8, or 4 on the left reel R1, the symbol number PN = 21, 17, 13, 8, or 4 on the middle reel R2, This is an arrangement of symbols of symbol number PN = 21, 17, 12, 8, or 4 on the right reel R3.

  5) Watermelon role This role is a symbol of symbol number PN = 21, 16, 11, 6, or 2 on the left reel R1, a symbol of symbol number PN = 19, 15, 10, 6, or 2 on the middle reel R2, This is an arrangement of symbols of symbol number PN = 20, 16, 11, 7, or 3 in the right reel R3.

  6) Cherry role This role only needs to stop when the symbol number PN = 18 or 13 on the left reel R1 is activated among the winning lines L1 to L5, regardless of the stop position of the other reels. is there.

  7) Replay role This role consists of a symbol number PN = 19, 14, 9, 5, or 3 on the left reel R1, a symbol number PN = 20, 16, 12, 7, or 3 on the middle reel R2. The symbol numbers PN = 19, 15, 10, 6, or 2 on the right reel R3. Even if a replay role is established, no medals are paid out, but replay is possible. Re-playing means playing a game again without newly inserting medals.

  For these roles, 1 to 15 payouts will be awarded, and advantageous game conditions such as big bonus and regular bonus will be granted regardless of whether or not there is a payout due to winning. There is a role in which a re-game that allows a game to be played under the same number of medal insertion conditions is given again without being inserted. In addition, since the success / failure of these combinations and the number of medals to be paid out (dividend) are determined by the gaming state, they are not always constant.

  In the present embodiment, 7 medals for the bell, 15 for the watermelon, and 2 medals for the cherry are performed, and the replay is preset as a role that allows replay. Among the various types of roles, the names corresponding to relatively low game values such as a bell role, watermelon role, cherry role, and replay role, such as a dividend or replay of about 2 to 15 cards, are collectively referred to as small. Called a role. On the other hand, when the BAR combination wins, the gaming state shifts to a 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. 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 the red 7 role or the white 7 role is established, the game state is changed from the normal game state to a special game state called a big bonus (hereinafter, the big bonus is abbreviated as “BB” if necessary). Migrate to During the big bonus period, in addition to being able to play regular bonuses up to three times, it is possible to establish a small role game with a high winning probability state up to 30 times. There is also a form in which the big bonus period ends when the number of acquired medals exceeds a predetermined number instead of the number of games. The big bonus is a more advantageous gaming state compared to the regular bonus. Further, a replay high probability state in which the winning probability of the replay prize is higher than the winning probability in the normal state is referred to as a replay time (hereinafter, the replay time is abbreviated as “RT” as necessary). And it is started when a predetermined condition is satisfied. The predetermined condition is appropriately determined from the characteristics of each gaming machine.

  In the following description, the former is referred to as BB RB and the latter is referred to as single RB in order to distinguish between the regular bonus in the big bonus and the regular bonus won or won alone. In addition, as a gaming state, the normal gaming state is “normal”, the big bonus period is “BB gaming”, the regular bonus period is “RB gaming”, and the RT period is Each of them is referred to as “RT gaming”.

  A predetermined prize group corresponds to the above-described combination, and one prize group may be assigned to each combination, or one or a plurality of combinations may be assigned to one prize group. In the present embodiment, the prize group corresponding to the red 7 role and the white 7 role is a BB prize (special prize), the bell group is a prize group corresponding to the bell role, the watermelon prize is a cherry group, and the cherry role is a prize group corresponding to the watermelon role. A cherry prize and a replay prize are set in advance as a corresponding prize group and a prize group corresponding to the replay role. Further, a JAC prize is set in advance as a prize group corresponding to a replay role assigned as a jack game role.

<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 the control board 30 as a main component.

  The control board 30 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 control board 30 excluding the transmission timing control circuit 36 via a bus (not shown). The CPU 31 controls each component by executing the control program CP. The control program CP 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 range of the count data CD is, for example, 0-16383, depending on the contents stored in a prize group lottery table TBL1, which will be 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 “16383” is about 0.5 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. In the present embodiment, as a work area necessary for executing various processes described later, a stop table group selection management work W1, a stop control group selection management work W2, and a specific stop for managing the number of executions of the specific stop control according to the present invention A control period management work W3 and a specific stop control lottery table selection management work W4 are respectively assigned.

  In addition to the control program CP, 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 their medal payout numbers are stored in association with each other. Detailed descriptions of the prize group lottery table group TBL1 and the stop table group TBL2 will be described later.

  The transmission timing control circuit 36 and the data transmission circuit 37 play a role of transmitting the types of roles determined by the internal lottery to the liquid crystal display control circuit 61. The liquid crystal display control circuit 61 includes a ROM that stores various image data. The image data is read out as needed and supplied to the liquid crystal display device 62. The liquid crystal display device 62 displays various images based on the image data. For example, informing about the winning results of the BB prize or the RB prize, the CPU 31 sends the internal lottery data ISD to the liquid crystal display control circuit 61 via the data sending circuit 37, and the liquid crystal display control circuit 61 instructs the internal lottery data ISD. The image data corresponding to the winning prize is read from the ROM, and the read image data is supplied to the liquid crystal display device 62.

  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. Although not shown, when a medal payout device is provided, a control signal may be output from the output port 39 to pay out medals, and the payout number may be counted from the input port 38.

  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. 6 is a timing chart showing the relationship among 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 (red 7) having 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, a symbol (plum) 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 rotates once and the symbol of symbol number PN = 1 (red 7) 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 symbol display state 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 prize group lottery table group TBL1 and the stop table group TBL2 stored in the ROM 35 will be described. The prize group lottery table group TBL1 includes a plurality of prize group lottery tables. CPU31 performs internal lottery for every game using the prize group lottery table selected according to the gaming state. As a prize group lottery table, a table used for a normal game, a table used for a BB game, a table used for an RB game, and a table used for an RT game are prepared. Furthermore, tables used for the base game include a table used when a BB winning flag and an RB winning flag, which will be described later, are cleared, and a table used when these winning flags are set.

  As an example, FIG. 7 shows the stored contents of the prize group lottery table TBL11 for the base game. As shown in this figure, the prize group lottery table TBL11 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 a loss, and the value is “11437”. The lottery classification data stored in the third storage area ADR3 and the fourth storage area ADR4 correspond to the cherry prize and the bell prize, and the values are “1200” and “1300”, respectively.

  The CPU 31 specifies a winning group or a lost game for each game by comparing and comparing the value of the selected lottery classification in the selected prize group lottery table and the value of the sampling data SD under a predetermined process, and the result of the internal lottery. Internal lottery data ISD is generated. The internal lottery data ISD is, for example, 8-bit data as shown in FIG. 8, and the first bit (b0) is the BB prize, the second bit (b1) is the RB prize, and the third bit (b2) is It is possible to assign a replay prize to the fifth bit (b4), a watermelon prize to the sixth bit (b5), a bell prize to the seventh bit (b6), and a cherry prize to the eighth bit (b7). If any prize is won by the internal lottery, the CPU 31 sets the value of the corresponding bit to “1”, and if not, 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. FIG. 8 shows a case where the result of the internal lottery is a loss. The offset value (“˜H” means a hexadecimal number. The same applies hereinafter) will be described later.

  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 the BB winning flag or the RB winning flag to “1” is called “set”, and setting “0” is called “clear”. The same applies to prize groups corresponding to small roles. For a prize group corresponding to a small role, even if a game is won by internal lottery, no medals are paid out unless the game is won. That is, the winning flag of the prize group corresponding to the small role is cleared in the game. However, if the RB prize and the BB prize are won in an internal lottery of a certain game, the BB prize flag or the BB prize flag is not cleared until the game is won in the subsequent game without clearing the BB prize flag or the RB prize flag. 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 winning the RB prize and the BB prize. In the following description, a case where the BB winning flag is carried over as a gaming state is referred to as “inside the BB”, and a case where the RB winning flag is carried over is referred to as “inside the RB”.

  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 as stop position information 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 for such reel rotation control, and is prepared for each combination. Therefore, when a prize group is won as a result of the internal lottery, a predetermined number of stop tables are selected from the stop table group TBL2 according to the combination set corresponding to the prize group. The stop positions of the left, middle, and right reels R1, R2, and R3 are determined with reference to a stop table. The details of stop table selection processing and stop control will be described later.

  FIG. 9 schematically illustrates a part of the stop table group TBL2 according to the present embodiment. The stop table group TBL21 for losing used when the result of the internal lottery is lost, and the result of the internal lottery The stop table group TBL22 for BB prize used when BB prize is won is shown. The stop table group TBL21 for loss is divided into an A group and a B group. The A group includes a chance eye table 211A on which so-called chance eyes are displayed and a losing eye table 212 on which losing eyes are displayed. Group B includes only the chance eye table 211B. On the other hand, the BB award stop table group TBL22 includes a chance eye table 221 and a reach eye table 222 in which a so-called reach eye appears. Although not shown in FIG. 9, the ROM 35 is a stop table in which a plurality of stop tables 231 that can win a combination (RB combination, watermelon combination, cherry combination, etc.) corresponding to a prize group other than the BB award are collected. A group TBL23 is also stored.

  Opportunity is a symbol that is displayed even when the result of the internal lottery is lost, among the combinations of symbols that are displayed when the BB prize or RB prize is won internally and the corresponding role is not won. A combination of In general, the player cannot know the result of the internal lottery. Therefore, if the chances are defined from the player's standpoint, it means a combination of symbols that can be expected to win the BB Award or the RB Award internally. There is a so-called reach eye as a concept similar to this, but the reach eye is distinguished from the chance eye in that it is a combination of symbols that is not displayed when the result of the internal lottery is lost. Therefore, when the reach is displayed, it is always determined that the BB prize or RB prize is won internally.

  A specific combination of symbols of chance and reach may be set as appropriate, but a feature may be imparted so that the player can easily recognize it. For example, as shown in each of (a) and (b) of FIG. 10, the chances of the present embodiment are obtained by using a small role symbol that is easy to align even if the player does not aim, and having some kind of law. , Is set to give the player some discomfort.

  In the chance eye tables 211A, 211B, and 221 and the reach eye table 222, the advance frame number data that enables the display of the chance eye and the reach eye is described. The chance eye table 221 belonging to the stop table group TBL22 for the BB award stores the advance frame number data that can be won for the red 7 role and the white 7 role, while belonging to the stop table group TBL21 for losing The chance eye tables 211A and 211B differ from each other in that advance frame number data that cannot be won in any combination is described. In particular, in the present embodiment, the advance frame number data in which chance chances are always displayed is described in the B group chance eye table 211B. FIG. 11 shows an example of the chance eye table 221 belonging to the stop table group TBL22 for the BB prize, and FIG. 12 shows an example of the chance eye table 211B of the B group. In these drawings, the symbols on the reels R1, R2, and R3 shown in FIG. 4 are shown in contrast with each other for easy understanding. The tables illustrated in these drawings are stop tables for stopping predetermined symbols on the winning line L1.

  As shown in FIG. 11, the chance eye table 221 includes, as the advance frame data DAT1, a winning portion DAT1a that wins a red 7 role or a white 7 role, and a non-winning portion DAT1b that cannot receive a prize. It is. The non-winning portion DAT1b includes a chance eye portion DAT1c where the chance eye shown in FIG. 10A is displayed. For example, when the symbol numbers acquired in response to the operation of the reel stop buttons 7a, 7b, 7c by the player are PN = 6 for the left reel R1, PN = 7 for the middle reel R2, and PN = 5 for the right reel R3, the CPU 31 The winning portion DAT1a of the chance eye table 221 is referred to. As a result, the CPU 31 advances the left reel R1 by one frame, the middle reel R2 by two frames, the right reel R3 by four frames, and stops the reels R1, R2, and R3, respectively. As a result, a combination of red 7-red 7-red 7 symbols is displayed on the winning line L1, and a red 7 combination is won. When the acquired symbol number is PN = 14 for the left reel R1, PN = 16 for the middle reel R2, and PN = 17 for the right reel R3, the CPU 31 refers to the chance eye portion DAT1c, and as a result, the red 7 Although the winning combination or the white 7 winning combination is not won, a combination of bell-bell-plum symbols (FIG. 10A) as a chance is displayed on the winning line L1. As is clear from this figure, when the acquired symbol number straddles each part DAT1a, DAT1b, DAT1c (for example, left: PN = 4, middle: PN = 14, right: PN = 12), chances are A combination of symbols other than the eyes is displayed and no prize is awarded.

  On the other hand, as shown in FIG. 12, the advance eye data DAT2 in which the chance eye is always displayed is stored in the chance eye table 211B as described above. That is, when the chance eye table 211B is selected, the stop button 7a, 7b, 7c is not dependent on the symbol number acquired in response to the operation of the reel stop buttons 7a, 7b, 7c by the player. The bell-bell-plum symbol combination (FIG. 10 (a)) is displayed on the winning line L1 without depending on the operation timing. That is, the frame data DAT2 is configured so that the so-called pull-in rate relating to the chance symbol combination is 100%. The chance eye table 211B includes a common part DAT2a common to the chance eye table 221 of FIG. 11 as the advance frame number data DAT2.

  Although not shown, in the chance eye table 211A belonging to the A group of the stop table group TBL21 for loss, the common part common to the chance eye table 221 in FIG. 11 is used as the advance frame number data stored in this table. It is included. Accordingly, even when the chance eye table 211A is selected, the chance eye shown in FIG. 10A can be displayed, but the pull-in rate is not 100% as in the chance eye table 211B of the B group. The appearance rate of chance eyes is set lower than that in the chance eye table 211B.

<1-4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. 13 and 14 are flowcharts showing the operation of the CPU 31 controlling the slot machine 1 from the start to the end of one game according to the control program CP. One game is started by a bet operation by a player, which will be described later, and is ended when the next bet operation is permitted (the prohibition is released). Then, the next game starts with the next betting operation.

  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 S1). Proceed to S2.

  In step S <b> 2, 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 S3). 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 corresponding to the gaming state (step S4). As described above, the gaming state is “normal” in the normal gaming state, “BB gaming” during the big bonus period, “RB gaming” during the regular bonus period, “RT gaming during the RT game period” "Inside BB" when the BB winning flag is carried over, and "Inside RB" when carrying the RB winning flag.

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

  Next, the CPU 31 executes an internal lottery process (step S5). In the internal lottery process, based on the sampling data SD generated according to the operation timing of the start lever 6, the prize group lottery table set in step S4 is referred to specify either winning or losing of each prize group. When the CPU 31 executes this process, the CPU 31 functions as a prize group lottery means of the present invention. When the internal lottery process ends, the CPU 31 determines whether or not the gaming state is “RB in progress” (step S6).

(1: Winning flag set processing)
When the gaming state is “not in RB”, the process proceeds to the subsequent step S7, and as shown in FIG. 15, the process of setting each winning flag is performed according to the result of the internal lottery (steps S701 to S717). In the process of FIG. 15, if the BB prize or RB prize is won during the RT game, the BB winning flag, the single RB winning flag, and the RB winning flag during BB are set (steps S702, S705, and S708). ). Then, after the BB winning flag and the single RB winning flag are set, the RT gaming flag and the RT game count are cleared (steps S703 and S706).

(2: Stop table group selection process)
Returning to FIG. 13 and FIG. 14, when the winning flag setting process is completed, the CPU 31 performs a reel stop table group TBL2 selection process (step S8). The contents of this selection process are shown in FIGS. When the CPU 31 executes this selection process, the CPU 31 functions as a stop table selection unit of the present invention. As shown in these figures, since the CPU 31 selects a stop table corresponding to each prize group or loss, a link as a stop table specifying means in which a link pointer for specifying the storage destination of the ROM 35 of the stop table is described. The table TBL4 is referenced (step S801). The link table TBL4 is stored in the ROM 35 (FIG. 5). FIG. 18 shows an example of the link table TBL4. In the figure, “losing normal” indicates that a stop table belonging to the A group (for example, the chance table 211A) is selected from the stop table group TBL21 for loss, and “losing specification” is a stop table belonging to the B group (for example, Each of the cases where the chance eye table 211B) is selected is shown. Next, the CPU 31 refers to the internal lottery data ISD (FIG. 8) to determine whether or not the replay winning flag, watermelon winning flag, bell winning flag, cherry winning flag, BB winning flag, and RB winning flag are set. Are respectively determined (steps S802 to 807).

  Then, the CPU 31 offsets the address of the link table TBL4 in accordance with the offset value (FIG. 8) associated with each winning flag (step S808 to step S813), and stops the link pointer stored at the offset address. The data is stored in the group selection management work W1 and the process is terminated (steps S814 to S819). For example, referring to FIG. 8 and FIG. 18, when the BB winning flag is set, the offset value is (1 × 2) H = 2H, so the head address of the link table TBL4: 2H offset from 0100H Is done. Then, a link pointer (1200H) that specifies the storage location of the BB stop table is acquired, and this value is stored in the stop table group selection management work W1. The same process is performed when winning other prize groups.

  On the other hand, if all negative determinations are made in steps S802 to S807, the result of the internal lottery is a loss, so the address of the link table TBL4 is offset according to the offset value (FIG. 8) associated with the loss (step S820), the process proceeds to the next step S821. In step S821, the type of stop table group for losing is selected. Although details of this process will be described later, it is determined by this process whether the stop table belonging to the A group or the B group is selected from the stop table group for loss TBL21 (see FIG. 9). It is determined whether to execute specific stop control using the stop table or normal stop control using the stop table of the A group.

  In the next step S822, the value of the stop control group selection management work W2 reflecting the result of the type selection process of the stop table group for loss is referred to, and whether or not this value indicates the execution of the specific stop control. Determine. The stop control group selection management work W2 manages whether specific stop control or normal stop control is to be executed. In this embodiment, when the normal stop control is to be performed (hereinafter referred to as “normal”), the value 00H However, when specific stop control is to be performed (hereinafter referred to as “specific”), the value 01H is stored. An offset value corresponding to the value of the stop control group selection management work W2 is set. Incidentally, in the case of “specific”, the value (01 × 2) H is set as the offset value.

  If it is determined as “specific” as a result of the determination in step S822 (YES), the CPU 31 addresses the link table TBL4 offset in step S820 (0106H) as indicated by the dashed arrow in FIG. The address is further offset according to the offset value in the case of “specific” from (step S823). And the link pointer memorize | stored in the address after the offset is stored in the stop table group selection management work W1, and a process is complete | finished. On the other hand, if the result of determination in step S822 is “normal” (NO), the link pointer stored in the address (0106H) of the link table TBL4 offset in step S820 is managed as stop table group selection. It stores in the work W1 and ends the process.

(2-1: Type selection processing of stop table group for loss)
Next, the contents of the type selection process for the stop table group for losing executed in step S821 will be described with reference to FIG. As shown in FIG. 19, the CPU 31 first determines whether or not the number of games is set in the specific stop control period management work W3 (step S8001). The specific stop control period management work W3 manages the number of executions of the specific stop control as described above, and stores the number of games for which the specific stop control has been executed. When the number of games is set in the management work W3, it is during the specific stop control period in which the frequency of executing the specific stop control is increased over a plurality of games. On the other hand, when the number of games is not set in the management work W3, the normal stop control is being executed, not during the specific stop control period. Therefore, when the number of games is not set in the management work W3 (NO), the CPU 31 advances the process to step S8002, and determines whether or not to shift to the specific stop control period. 20) is executed.

(2-1-1: Specific stop control period transition lottery process)
As shown in FIG. 20, the CPU 31 obtains the head address of the transfer lottery table TBL5 (step S8021). The transfer lottery table TBL5 is stored in the ROM 35, and a predetermined lottery value is stored. By appropriately increasing or decreasing the predetermined lottery value, it is possible to set the probability of transition to the specific stop control period. The lottery value may be determined as appropriate. For example, as shown in FIG. 21, a plurality of prize group lottery table groups are provided according to the prize group winning frequency, and can be set in stages (stage setting). The lottery value can be changed according to the stage setting. Further, one lottery value may be set regardless of the stage setting. Next, the CPU 31 acquires a random number value (step S8022), and acquires a lottery value stored at the address acquired in step S8021 (step S8023). The acquisition of the random value may be realized by sampling an arbitrary value from the count data CD output from the sequence generator 33 shown in FIG.

  Next, the CPU 31 compares the random number value with the lottery value (step S8024) and determines whether or not it is a win (step S8025). As a result, if unsuccessful, the process is finished as it is, and if it is won, the process proceeds to step S8026, and a value indicating one game (1G) is stored (set) in the specific stop control period management work W3. ) To finish the process. By executing the above specific stop control period shift lottery process, the CPU 31 functions as a shift determination unit of the present invention. Winning the transfer lottery corresponds to the transfer condition of the present invention.

  Returning to FIG. 19, subsequently, the CPU 31 determines whether or not the stored content of the specific stop control period management management work W3 is 0G, that is, whether or not the above-mentioned transition lottery has been won (step S8003). This is because the number of games (1G) is stored in the management work W3 when the transfer lottery is won (step S8026 in FIG. 20). When the storage content of the management work W3 is 0G, the subsequent processing is skipped and the processing is terminated. On the other hand, if the result in Step S8003 is negative, it is determined that the process shifts to the specific stop control period. Therefore, the process proceeds to the next step S8004, and a specific stop control lottery table selection lottery process is executed.

(2-1-2: Specific stop control lottery table selection lottery process)
In the present embodiment, whether or not the specific stop control is permitted is determined by lottery. This lottery is performed using a specific stop control lottery table TBL6 in which a lottery value for determining the lottery probability is designated for each game. As shown in FIGS. 23A to 23C, the specific stop control lottery table TBL6 includes a plurality of types of specific stop control lottery tables TBL6A to TBL6C that are designated with different lottery values. The process of FIG. 22 is a lottery process performed to select one table from these specific stop control lottery tables TBL6A to TBLC.

  As shown in FIG. 22, the CPU 31 obtains the head address of the table type lottery table TBL7 (step S8041). The table type lottery table TBL7 is stored in the ROM 35, and the lottery values are stored in correspondence with the specific stop control lottery tables TBL6A, TBL6B, and TBL6C. The selection probability of the specific stop control lottery tables TBL6A, TBL6B, and TBL6C can be set by appropriately changing the lottery value. For example, in this embodiment, lottery values are set as shown in FIG. Next, the CPU 31 acquires a random number value (step S8042), and acquires a lottery value stored at the address of the ROM 35 acquired in step S8041 (step S8043). In the present embodiment, a random value is obtained by sampling an arbitrary value from the count data CD output from the sequence generator 33 shown in FIG.

  Next, the CPU 31 compares the random number value with the lottery value (step S8044) and determines whether or not it is a win (step S8045). As a result, in the case of unsuccessful selection, the lottery of the specific stop control lottery table TBL6A is not selected. Therefore, in order to perform the lottery of the next specific stop control lottery table TBL6B, the address of the table type lottery table TBL7 is offset (step S8046) and added to the lottery value before the offset. Thereafter, the offset is continued up to the number of the specific stop control lottery table TBL6 (3 in the present embodiment) until it is determined to be won in step S8044 (see step S8047). Accordingly, one table is selected from the specific stop control lottery tables TBL6A, TBL6B, and TBL6C with the set selection probability. Next, in the next step S8048, the CPU 31 stores the address of the ROM 35 in which the selected specific stop control lottery table TBL6 is stored in the specific stop control lottery table selection management work W4, and ends the process.

(2-1-3: Specific stop control execution lottery process)
Returning to FIG. 19, when the CPU 31 finishes the specific stop control lottery table selection lottery process (step S8004), the CPU 31 performs a specific stop control execution lottery process in the next step S8005. When the CPU 31 executes this process, the CPU 31 functions as a determination unit that determines whether to execute the specific stop control according to the present invention. FIG. 25 is a flowchart showing the contents of the specific stop control execution lottery process. As shown in this figure, the CPU 31 refers to the specific stop control lottery table selection management work W4, and acquires the head address of the specific stop control lottery table based on the address stored in the management work W4 (step S8051). ). Next, a random value is acquired (step S8052). In the present embodiment, a random value is obtained by sampling an arbitrary value from the count data CD output from the sequence generator 33 shown in FIG. Next, the CPU 31 refers to the number of games stored in the specific stop control period management work W3 (step S8053), and acquires a lottery value corresponding to the number of games based on the address acquired in step S8051 (step S8054). ). Next, the random value acquired in step S8052 and the lottery value acquired in step S8053 are compared (step S8055), and it is determined whether or not the winning is performed, that is, whether or not to execute the specific stop control (step S8056). For example, when the specific stop control lottery table TBL6A (FIG. 23 (a)) is selected in the process of FIG. 22 described above and the number of games in the stop control period management work is one game, it is acquired in step S8053. The lottery value is 16384. Since the value of the count data CD from which the random number is acquired is a value from “0” to “16383” as described above, in this case, the winning is performed with a probability of 100% and the specific stop control is executed. Will be. When the CPU 31 executes steps S8051 to S8056, the CPU 31 functions as a specific stop control lottery means of the present invention.

  Next, if not won in step S8056, “normal” is set in the stop control group selection management work W2 to perform normal stop control in the game (step S8057), while if won in step S8056. Sets “special” to the management work W2 to perform specific stop control, and the process ends (step S8058). As described above, the value 01H is set for “specific”, and the value 00H is set for “normal”.

  In the above processing, the CPU 31 sets the value of the specific stop control period management work W3 when shifting to the specific stop control period (step S8026 in FIG. 20), and sets the value of the management work W3 to 1 each time the specific stop control is executed. By adding (step S2106 in FIG. 33) and determining whether or not the value of the management work W3 has reached the predetermined number of games 5 (step S2102 in FIG. 33), the CPU 31 performs the specific stop control period of the present invention. Functions as a management means.

(3: Winning flag set processing, reel stop table group selection processing (during RB game))
Returning to FIG. 13 and FIG. 14, if it is determined in step S6 that the current gaming state is “RB in progress”, the CPU 31 proceeds to step S9 and wins the JAC prize as shown in FIG. (Step S901), if the JAC prize is won, the JAC winning flag is set (step S902). Then, returning to FIGS. 13 and 14, the process proceeds to step S <b> 10. In this process, as shown in FIG. 27, it is first determined whether or not the JAC winning flag is set (step S1001). If the JAC winning flag is set, the JAC stop table group is selected and the process ends (step S1002). On the other hand, when the JAC winning flag is not set, the stop table group for losing is selected (step S1003).

(4: Reel stop control process)
The description returns to FIGS. 13 and 14. When the selection of the stop table group is completed, the CPU 31 then starts reel rotation (step S11) and executes a reel stop control process (step S12). FIG. 28 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 (step S1201).

  When the first stop operation of the reel stop button is detected, the CPU 31 acquires the stop button numbers (button types) of the currently pressed reel stop buttons 7a to 7c (step S1202), and the pattern immediately after the stop operation is obtained. The number PN is acquired (step S1203). Specifically, the CPU 31 detects the timing at which the reel stop buttons 7a, 7b, 7c are pressed 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 refers to the stop table group selection management work W1 and refers to the stop table group stored in the address destination stored therein (step S1204). Next, a usable stop table combination is identified from the stop button number acquired in step S1202 and the symbol number acquired in step S1203 (step S1205), and the value of the link pointer of one stop table is acquired from the combination of stop tables. (Step S1206). This link pointer designates the address of the ROM 35 in which stop table data is stored. Then, data corresponding to the symbol number (advance frame number data) is acquired from the stop table stored at the address of the link pointer value acquired in step S1206 (step S1207), and the stop operation is performed based on the data. The reels are stopped (step S1208).

  Subsequently, 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 S1209). If there is a second button stop operation, acquisition of a stop button number ( Step S1210) and symbol number acquisition (step S1211) are executed. Next, the value of the link pointer of one stop table used for the second stop is acquired from the stop button number acquired in step S1210 and the symbol number acquired in step S1211 (step S1212), and data corresponding to the symbol number is obtained. Obtain (step S1213). Next, the reel that has been stopped based on the acquired data is stopped (step S1214). 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 S1215). When the third button stop operation is performed, acquisition of the stop button number ( Step S1216), symbol number acquisition (step S1217), and reel stop (step S1218) are executed. Since the processes of steps S1210 and S1211, and steps S1216 and S1217 are the same as the processes of steps S1202 and S1203, detailed description thereof is omitted.

  The CPU 31 executes the stop table group selection process of FIGS. 16 and 17 and the reel stop control process of FIG. 28 to control the stop operation of the reels R1 to R3 corresponding to the winning combination corresponding to the winning group. (So-called symbol pull-in control), or control to stop the reels R1 to R3 (so-called kick-off control) so that the symbol corresponding to the winning combination is not aligned on the winning line in the case of a loss in the internal lottery, The CPU 31 functions as stop control means.

(5: RT game end determination process)
The description returns to FIGS. 13 and 14. Next, the CPU 31 performs RT game end determination processing for determining whether or not the RT game has ended (step S13). FIG. 29 is a flowchart showing the contents of this process. As shown in this figure, the CPU 31 first refers to the RT gaming flag to determine whether or not the current gaming state is an RT game (step S1301). When the RT game is not in progress, the subsequent processing is skipped and the current processing ends. On the other hand, when it is determined that the RT game is being played, 1 is subtracted from the number of RT game executions (RT game number) set in the RT game setting process (see FIG. 18) described later (step S1302).

  Subsequently, the CPU 31 determines whether or not the remaining RT game count (remaining RT game count) is 0 (step S1303). When the number of remaining RT games is 0, the RT game is ended in the current game, so the RT gaming flag is cleared (step S1304). On the other hand, when the remaining RT game number is not 0, the remaining RT game number is displayed on a display device (not shown) (step S1305). The number of RT games is managed by these processes, and the CPU 31 functions as a replay high probability game number management means of the present invention.

  The description returns to FIGS. 13 and 14. Next, the CPU 31 determines whether or not a winning combination corresponding to the replay prize has been won (step S14). When a winning combination corresponding to the replay prize is won, 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 winning combination corresponding to the replay prize, the CPU 31 clears the replay winning flag (step S15), and returns the process to step S2.

(6: Winning determination process)
On the other hand, when it is determined that the winning combination corresponding to the replay prize is not won, the CPU 31 determines whether or not the current gaming state is an RB game (step S16). When the RB game is not being played, the process proceeds to step S17 and a winning determination process is performed. As shown in FIG. 30, the CPU 31 sequentially determines whether or not a watermelon role, a bell role, or a cherry role is won based on a winning flag (steps S1701 to S1703), and refers to the winning symbol combination table TBL3. Then, each unit is controlled to pay out the number of medals according to the winning combination (steps S1704 to S1706).

  Next, the CPU 31 sequentially determines whether or not a single RB has been won (step S1707) or whether or not a RB in the BB has been won (step S1708). The medal payout process is performed according to the winning mode (steps S1709 and S1710), and the RB game start process is performed (steps S1711 and S1712). In the RB game start process, although not shown, an RB gaming flag is set, the number of JAC winnings is set (for example, 8 times), and the number of JAC games is set (for example, 12 times).

  Subsequently, in step S1713, the CPU 31 determines whether or not the BB game is being played. If the current gaming state is a BB game, the process proceeds to a BB game end determination process (step S1714). In this process, although not shown in the figure, in the BB game, whether the regular bonus (RB during BB) has been played up to 3 times, or whether the game in the gaming state in which the small role is won with a high probability has been played up to 30 times If the predetermined number of games has been exceeded, the BB gaming flag is cleared. As another example, it is determined whether or not the number of acquired medals exceeds a predetermined number (for example, 450), and when it exceeds the predetermined number, the BB gaming flag is cleared. On the other hand, when the number of acquired medals does not reach the predetermined number, the number of acquired medals during the BB game is displayed on a display means (not shown).

  Next, the CPU 31 determines whether or not a winning combination corresponding to the BB prize has been won (step S1715), and if a winning combination corresponding to the BB prize has been won, a predetermined medal is paid out (step S1716). ) A BB game start process is performed (step S1717). In the BB game start process, although not shown, a BB gaming flag is set and the count value of the number of acquired medals is cleared.

(7: Winning determination process (RB game))
The description returns to FIGS. 13 and 14. When it is determined in step S16 that the gaming state is in the RB game, the process proceeds to step S18, and a winning determination process in the RB game is executed. In this winning determination process, as shown in FIG. 31, it is determined whether or not the winning combination corresponding to the JAC award has been won (step S1801). A medal payout process is performed (step S1802). On the other hand, if no winning combination corresponding to the JAC prize has been won, it is determined whether or not the current gaming state is an RB game (step S1803). If the RB game is being played, the process proceeds to step S1804, and an RB game end determination process is performed. In this process, although not shown, the number of winnings in the combination corresponding to the JAC award set as a management index for the progress of the RB game is managed. When this number reaches the predetermined number, the RB gaming flag is cleared and the RB game is ended. On the other hand, when the predetermined number of times is not reached, the number of remaining JAC games is displayed. Next, the CPU 31 determines whether or not the gaming state is a BB game (step S1805). When it is determined that the BB game is being played, a BB game end determination process is performed (step S1806). This process is the same as the process in step S1714 of FIG. When the CPU 31 executes the above winning determination process and the process of step S14 in FIG. 13, the CPU 31 functions as a winning determination means.

(8: RT game setting process)
Returning to FIGS. 13 and 14, the CPU 31 determines whether or not the RT game start condition is satisfied (step S19). RT game start conditions can be determined as appropriate. For example, the winning of a predetermined role, the end of the BB game, or the digestion of the predetermined number of games after the end of the BB game can be exemplified. In this embodiment, a watermelon award or a cherry award is awarded. If the RT game start condition is satisfied in step S19, the process proceeds to step S20, and the RT game setting process is executed. FIG. 32 shows the contents of the RT game setting process. As shown in this figure, the CPU 31 first determines the number of RT game executions (RT game number) by lottery (step S2001). Subsequently, when it is determined that the winning of the bell 2 role is determined during the RT game, an addition process of adding a predetermined number of times to the current RT game number is performed (step S2002). Subsequently, it is determined whether or not the number of RT games is 0 (step S2003). If this is not 0, an RT gaming flag is set (step S2004). On the other hand, in the case of 0, step S2004 is skipped and the process ends. By executing the above processing, the gaming state can be switched during the RT game, and the CPU 31 functions as the gaming state switching means of the present invention.

(9: 1 game end processing)
The description returns to FIGS. 13 and 14. Next, the CPU 31 executes a one-game end process (step S21). FIG. 33 is a flowchart showing the contents of one game end processing. As shown in this figure, the CPU 31 determines whether or not the stored content of the specific stop control period management management work W3 is 0G, that is, whether or not it is during the specific stop control period (step S2101). If it is not during the specific stop control period, the process proceeds to step S2107. On the other hand, if it is during the specific stop control period, the CPU 31 determines whether or not the number of games stored in the specific stop control period management work W3 is the fifth game, that is, the end of the specific stop control period (step). S2102). This number of times may be set appropriately. When the number of executions of the specific stop control is 5 games and the specific stop control period is to be ended (YES), the management work W3 is 0 games (reset) (step S2103), and the normal stop is performed after the end of the specific stop control period. In order to make control selectable, the stop control group management work W2 is cleared (step S2104).

  On the other hand, when the management work W3 is less than 5 games in step S2102, (NO), it is determined whether or not it is lost by referring to the winning flag of the current game (step S2105). In the case of loss, the value of the management work W3 is incremented by 1 in step S2106, and the process proceeds to step S2107. On the other hand, if it is not lost, step S2106 is skipped and the value of management work W3 is maintained at the current value.

  In step S2107, the winning flag of the small role prize (bell, watermelon, cherry, etc.) is cleared. Next, the CPU 31 executes winning confirmation of the BB prize and RB prize and clearing processing of these winning flags, and ends the process (step S2108). The process of step S2108 is to confirm the carry over of the flag and clear the winning flag. Therefore, the winning flag is not cleared if the winning combination is not made.

  Returning to FIG. 13 and FIG. 14, when the one-game end process is finished, the CPU 31 releases the prohibition of the BET operation (step S <b> 22). Thus, one game is completed.

The operation of one game in the slot machine 1 has been described above. By repeating this operation, for example, the situation shown in FIG. 37 can be created. As is clear from this figure, when the specific stop control period is entered, the specific stop control is executed three times in five games, so the situation is similar to the situation inside the BB. In this example, since the Bell game is won in the second game, the special stop control is performed because the lottery for execution of the specific stop control is not selected in the fifth game (step S8005 in FIG. 19 and FIG. 25). I have not been told.
<2. Modification>
Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the invention is limited to the embodiments disclosed herein. However, the present invention can be changed as appropriate without departing from the spirit or concept of the invention that can be read from the claims and the entire specification, and a gaming machine and a control method therefor are also included in the technical scope of the present invention. Must be understood as being. For example, the following modifications are naturally included in the present invention.

  (1) For example, a case where a winning combination such as a cherry award or a watermelon award is not carried over internally and a prize is not won may be used as a trigger for the transition to the specific stop control period. In other words, the so-called losing of a small role is used as a trigger for the transition. Specifically, the transfer lottery process (step S8002 in FIG. 19, FIG. 20) is deleted, and steps S1718 to S1720 are added to the winning determination process (FIG. 30) as shown in FIG. In the form of FIG. 34, it is determined whether either the cherry role or the watermelon role has been missed (steps S1718, S1719), and when these are missed, the specific stop control period management work W3 is set to one game. It was. Thereby, the so-called missing of the small role can be used as an opportunity for the transition to the specific stop control period.

  (2) In the above embodiment, the specific stop control period and the RT game period are not associated with each other, but the number of RT games can be managed as the number of executions of the specific stop control. For example, the transition to the RT game may be used as an opportunity to shift to the specific stop control period, and the specific stop control period may be ended in synchronization with the end of the RT game. With this configuration, the management means for managing the RT game can be used for the management of the specific stop control, so that it is not necessary to provide a dedicated management means, and the configuration can be simplified and the storage capacity can be reduced. In this form, the transition of the RT game corresponds to the transition condition of the present invention. In this case, the above-described replay high probability game number management means corresponds to the specific stop control period management means.

  (3) In the above embodiment, whether to execute the specific stop control is determined by lottery using the specific stop control lottery tables TBL6A to CBL shown in FIG. May be specified. In this case, for example, as shown in FIG. 35, an execution permission / inhibition designation table TBL8A in which a value (“specific” or “normal”) to be stored in the specific stop control group management work W3 is designated for each game is used. Specific stop control may be executed. If comprised in this way, the selection process (FIG. 19, step S8004, FIG. 22) of a specific stop control lottery table becomes unnecessary, and a structure can be simplified. In addition, since the pattern of whether or not to execute the specific stop control can be set without being influenced by chance, the intention of the designer can be accurately reflected. Further, the execution permission / inhibition designation table TBL8B shown in FIG. 36 may be used. In this table, since the link pointer shown in FIG. 18 is designated according to whether or not the execution of the specific stop control is permitted, the specific stop control group management work W3 becomes unnecessary, which can contribute to the compression of the data capacity. With these forms, the CPU 31 can function as the determining means of the present invention.

  (4) In the above embodiment, the loss stop table group TBL21 is configured as shown in FIG. 9, but the A group may be configured by only the loss eye table 212. Then, since the group A is configured such that the chances stop appearing and the specific stop control appears continuously only during the specific control period, the special prize group for the player when the chances appear due to the specific stop control It can be made to function so that the expectation of winning is higher.

  (5) In the above embodiment, as an example of using the internal lottery data ISD consisting of 8-bit data as means for managing the internal lottery result, the winning for managing the internal lottery result as the work area of the RAM 34 is exemplified. A management work may be provided, a value corresponding to the prize group may be assigned to the winning management work, and the offset value may correspond to the assigned value. This also makes it possible to select a stop table group according to the winning result.

  (6) The present invention can also be understood as a game program or a game machine imitating the slot machine described above. In this case, instead of the reels R1 to R3, the images of the reels R1 to R3 may be displayed on the display, and their operations may be controlled according to the game program. Further, the present invention can be applied to a video slot for displaying an image of a reel on a display such as a liquid crystal display device instead of the mechanical reels R1 to R3.

  (7) Further, as the above-described slot machine, an insertion slot capable of taking a pachinko ball instead of a medal is provided, and for example, a BET corresponding to one medal can be made with five pachinko balls. . In this slot machine, game characteristics are the same except that pachinko balls are used instead of medals as game media. Since this slot machine uses the same game medium as the pachinko machine, it can be installed on the game island where the pachinko machine is installed by replacing the pachinko machine.
