Description

  The present invention relates to a gaming machine such as a slot machine.

  As a gaming machine that stops after rotating a plurality of reels, for example, there is a slot machine. In the slot machine, a plurality of symbols are given to the outer peripheral portion of each reel, and a part of the symbols given to each reel is visible through the display window. Then, when the player inserts a medal, an effective line is set, and then the player operates the start lever to play a big bonus (hereinafter referred to as “BB”) role or small role in the slot machine. In addition, a lottery such as a re-game is performed and each reel starts to rotate. After each reel starts to rotate, each reel is sequentially stopped to finish one game. When all reels stop rotating, the winning combination will be awarded if the combination of the winning combination on the active line is stopped, and the player will receive a medal reward or a game state transition privilege. Is done. Therefore, it is common for a player to watch a changing symbol and operate a stop switch so that the predetermined symbol stops on the active line. In other words, the player can actively participate in the game. This is a feature of slot machines.

In addition to the BB state that shifts when a BB winning is established, the game state advantageous to the player includes a replay time (hereinafter referred to as “RT”) state in which the probability of winning a re-game is higher than the normal state. There is a slot machine. In the RT state, that a high probability of establishment of re-winning game as a result of the re-game winning probability is high. The RT state shifts when a predetermined start condition is satisfied, for example, after the end of the BB state, and is ended when an end condition such as a predetermined number of games is played or a BB is won. Is common (see, for example, Patent Document 1). In recent years, a slot machine having a plurality of RT states with different termination conditions has also been proposed.

It can be expected to be suppressed. Therefore, it becomes possible for the player to select whether or not to operate the stop operation means in order to establish a specific prize corresponding to the winning combination according to the situation at that time, regardless of the length of game time that can be played. It is possible for the player to entertain a game under a specific gaming state. For example, a player who can only play a game of the first number or less than the first number may shift to the first specific game state in which an increase in game media owned by the player can be expected, and the second number of times. This is because a player who can execute a greater number of games and wants to enjoy a gaming state that is more advantageous than the first gaming state for as long as possible may shift to the second specific gaming state.

  Note that, in a gaming machine in which the player can select the number of game media when executing the game, the lottery information setting means is configured such that, when the gaming state is the first specific gaming state, the expected value is determined by the player. The lottery information is set to be higher than the number of selected game media, and when the game state is the second specific game state, the expected value is lower than the number of game media selected by the player. If it is set as the structure which sets lottery information, it can anticipate having the effect similar to the effect mentioned above.

It is expected that more game media will decrease than the expected decrease in game media. That is, when the second number of games are performed after shifting to any one of the specific gaming states, the player's degree of advantage is that the transition to the second specific gaming state is higher than the first specific gaming state. Becomes larger. By adopting such a configuration, it is possible to clarify the intention of allowing the player to select one of the first specific game state and the second specific game state, and to specify a specific game for the player regardless of the length of game time that can be played. It is possible to entertain games under conditions. It is assumed that a general player plays a game while expecting to have more game media at the stage of ending the game. For this reason, for example, a player who can execute only a first number of games or a number of games less than the first number may shift to the first specific game state in which an increase in game media owned by the player can be expected if he / she plays. This is because a player who can execute the second number of games may shift to the second specific game state in which the decrease in the game medium can be expected.

  Means 12. In any one of the above means 8 to 11, the lottery information setting means gives game media to the number of game media used when a game is executed in the first specific game state and the first game state. The expected value of the ratio of the number and the expected value of the ratio of the number of game media given to the number of game media used when the game is executed in the second specific game state and the first game state are approximately A gaming machine, wherein lottery information in each gaming state is set to be equal.

  According to the means 12, the expected value of the ratio of the number of game media given to the number of game media used when the game is executed under the first specific game state and the first game state, and under the second specific game state In addition, the lottery information in each gaming state is set so that the expected value of the ratio of the number of game media to be used with respect to the number of game media used when the game is executed in the first game state is substantially equal. In other words, when the game is repeatedly executed, the player's degree of advantage in the case where the game is executed by shifting to the first specific game state and the case where the game is executed by changing to the second specific game state. Almost equal. By adopting such a configuration, the player can select which specific gaming state to shift to, so that the player can enjoy the games in each specific gaming state, and has a plurality of specific gaming states. It is possible to suppress the dilution of the intention. That is, the expected value of the ratio of the number of game media given to the number of game media used when the game is executed under the first specific game state and the first game state, and under the second specific game state and the first game When there is a difference between the expected value of the ratio of the number of game media given to the number of game media used when the game is executed under the state, the expected value is higher unless there are special circumstances. This is because it is assumed that the game is executed with the expectation that the game state is shifted to the specific game state and more game media can be owned.

  Note that “substantially equal” means that the first number of games are executed under the first specific game state, and the number of games obtained by subtracting the first number from the reciprocal of the transition probability to the first specific game state is the first game. When the game is executed under the state, the difference between the expected number of used game media and the number of use of the game medium and the second number of games are executed under the second specific game state, and the reciprocal of the transition probability to the second specific game state It means that the difference between the expected number of game media to be used and the number of uses is one or less when the number of games reduced by the second number of times is executed under the first game state.

If the stop operation means corresponding to the prescribed circulation display means is operated at a timing at which the first specific winning can be avoided and the second specific picture cannot reach the effective position, the second It is possible to avoid the establishment of a specific prize.

  Hereinafter, an embodiment in the case of application to a spinning cylinder type gaming machine which is a kind of gaming machine, specifically, a slot machine will be described in detail based on the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10 with the front door 12 closed, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 opened, and FIG. 5 is a rear view of the door 12, and FIG.

  As shown in FIGS. 1 to 5, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The casing 11 is formed in a box shape having an open front as a whole, and is attached by, for example, driving nails against a so-called island facility when installed in the game hall.

  A front door 12 is attached to the front side of the housing 11 so as to be openable and closable. That is, the housing 11 is provided with a pair of upper and lower support shafts 13a and 13b on the left side when viewed from the front, and the front door 12 has a bearing portion 14a at a position corresponding to each support shaft 13a and 13b. , 14b are provided. When the support shafts 13a and 13b are inserted into the bearing portions 14a and 14b, the front door 12 rotates about an opening / closing axis extending in the vertical direction connecting the support shafts 13a and 13b to the housing 11. The front door 12 can be opened and closed by rotating the front door 12 so as to be movable. Further, the front door 12 is brought into a locked state that cannot be opened by a locking device 20 provided on the back surface thereof. A key cylinder 21 that is integrated with the locking device 20 is provided on the upper right side of the front door 12, and is configured such that the locked state is released by a predetermined key operation on the key cylinder 21.

  A game panel 25 for notifying the player of the game state is provided above the center of the front door 12. The game panel 25 is formed with three vertically long display windows 26L, 26M, and 26R, and the inside of the slot machine 10 is visible through the display windows 26L, 26M, and 26R. The display windows 26L, 26M, and 26R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is divided into upper and lower parts by a partition plate 30, and a reel unit 31 constituting variable display means is attached to the upper part of the partition plate 30. The reel unit 31 includes a left reel 32L, a middle reel 32M, and a right reel 32R each formed in a cylindrical shape (annular shape). Each of the reels 32L, 32M, and 32R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 32L, 32M, and 32R are disposed on the same axis extending in the substantially horizontal direction, and the reels 32L, 32M, and 32R correspond to the display windows 26L, 26M, and 26R on a one-to-one basis. . Accordingly, a part of the surface of each reel 32L, 32M, 32R is visible through the corresponding display windows 26L, 26M, 26R. Further, when the reels 32L, 32M, and 32R are rotated forward, the surfaces of the reels 32L, 32M, and 32R are projected as if moving from top to bottom through the display windows 26L, 26M, and 26R.

  Here, the configuration of the reel unit 31 will be briefly described.

  Each of the reels 32L, 32M, and 32R is connected to a stepping motor, and each reel 32L, 32M, and 32R can be individually rotated, that is, independently driven by the driving of each stepping motor. . For example, the stepping motor is set to rotate once by giving a drive signal of 504 pulses (hereinafter also referred to as an excitation pulse), and the rotation position of the stepping motor, that is, the rotation position of the reel is determined by this excitation pulse. Be controlled. In the reel unit 31, a reel index sensor for detecting that the reel has made one rotation is installed on each of the reels 32L, 32M, and 32R. When the reel index sensor detects that the reel has made one rotation, a detection signal is output to the main controller 101 described later each time the reel is detected. Therefore, main controller 101 determines the angular position of each reel 32L, 32M, 32R for each rotation based on the detection signal of the reel index sensor and the number of excitation pulses output until the detection signal is input. It can be confirmed and corrected.

  On the outer peripheral surface of each reel 32L, 32M, 32R, a plurality of symbols as identification information are drawn in the long side direction (circumferential direction). More specifically, 21 symbols are drawn at equal intervals. Therefore, in order to switch the symbol at a predetermined position to the next symbol, it is necessary to output 24 pulses (= 504 pulses / 21 symbols) of excitation pulses. Further, the main control device 101 grasps the symbols visible from the display windows 26L, 26M, and 26R based on the number of excitation pulses output after the detection signal of the reel index sensor is input, or displays the display window. It is possible to perform control to stop a predetermined symbol at a position where it can be visually recognized from 26L, 26M, and 26R.

  Next, the symbols drawn on the reels 32L, 32M, 32R will be described.

  FIG. 6 shows a symbol arrangement of the left reel 32L, the middle reel 32M, and the right reel 32R. As shown in the figure, 21 symbols are arranged in a row on each of the reels 32L, 32M, and 32R. Further, numbers from 0 to 20 are assigned to the reels 32L, 32M, and 32R. These numbers are symbols that are visible to the main controller 101 from the display windows 26L, 26M, and 26R. Is a number for recognizing and not actually attached to the reels 32L, 32M, 32R. However, in the following description, the number is used for explanation.

  As symbols, “star” symbol (for example, 20th of left reel 32L), “cherry” symbol (for example, 19th of left reel 32L), “youth” symbol (for example, 18th of left reel 32L), “ “Bell” symbol (for example, 17th of left reel 32L), “Replay” symbol (for example, 16th of left reel 32L), “White 7” symbol (for example, 15th of left reel 32L), “Watermelon” symbol ( For example, there are eight types of 14th of the left reel 32L) and “red 7” symbol (for example, the third of the left reel 32L). As shown in FIG. 6, the number and arrangement order of various symbols on the reels 32L, 32M, and 32R are completely different.

  Each of the display windows 26L, 26M, and 26R is formed so that there are three symbols from which the entire symbol can be visually recognized out of the twenty-one symbols attached to the corresponding reel. Therefore, when all the reels 32L, 32M, and 32R are stopped, 3 × 3 = 9 symbols are visible through the display windows 26L, 26M, and 26R.

  In this slot machine 10, a total of five combination lines are set, connecting three positions where these nine symbols become visible, three in parallel in the horizontal direction and two in the diagonal direction. ing. More specifically, as shown in FIG. 7, as a combination line in the horizontal direction, an upper line L1 connecting the upper symbols of each reel 32L, 32M, 32R and a middle symbol of each reel 32L, 32M, 32R are connected. A line L2 and a lower line L3 connecting the lower symbols of the reels 32L, 32M, 32R are set. Further, as a combination line in the oblique direction, a lower right line L4 connecting the upper symbol of the left reel 32L, the middle symbol of the middle reel 32M, the lower symbol of the right reel 32R, the lower symbol of the left reel 32L, and the middle symbol of the middle reel 32M. A right rising line L5 connecting the upper symbol of the symbol and the right reel 32R is set. And, when the combination line is activated, that is, when the symbols are stopped in a predetermined combination on the effective line, a privilege that a predetermined number of medals as game media are paid out is given or the gaming state is shifted as winning establishment. Benefits are granted.

  FIG. 8 shows a combination of symbols for winning and a privilege to be given when winning.

  Small prizes for which medals are paid out include a bell prize, a watermelon prize, a single prize, and a cherry prize. When the “bell” symbols of the reels 32L, 32M, and 32R are stopped on the effective line, eight medals are paid out as a bell winning, and the “watermelon” symbols of the reels 32L, 32M, and 32R are effective lines. If you stop side by side, 6 medals will be paid out as a watermelon prize, and if you stop alongside the “Red 7” symbol, “Youth” symbol, and “White 7” symbol in order from the left on the active line, One medal is paid out as one winning combination. In addition, when the “cherry” symbol on the left reel 32L stops on the active line, two medals are paid out as a cherry prize. That is, in the case of a cherry winning, any symbol may be stopped on the active line for the middle reel 32M and the right reel 32R. In other words, if the combination of the “cherry” symbol of the left reel 32L and any symbol of the middle reel 32M and the right reel 32R stops on the active line, it can be said that the cherry prize is established. Therefore, when the “cherry” symbol stops at the position where the plurality of effective lines of the left reel 32L overlap (specifically, the upper stage and the lower stage), a cherry winning will be established on each effective line. 4 (= 2 × 2) medals are paid out. In the present embodiment, the “cherry” symbol on the left reel 32L stops at the upper or lower level so that a cherry winning is achieved, so that when the cherry winning is achieved, four medals are paid out. .

  As a state transition prize in which only the game state transition is performed, there is a BB prize. When the “red 7” symbols of the reels 32L, 32M, and 32R stop alongside the active line, the gaming state shifts to a big bonus state (hereinafter referred to as “BB state”) as a BB winning.

  As a prize to which a privilege other than medal payout or game state transition is given, there is a first re-game prize. When the “replay” symbols of the reels 42L, 42M, and 42R stop side by side on the active line, the medal payout and the game state transition are not performed as the first re-game winning, but the next medal is not inserted. A replay privilege that allows game play is given.

  In addition, as a prize to which both a re-game privilege and a state transition privilege are given, there are a second re-game prize and a third re-game prize. When stopped alongside the “Replay” symbol, “Replay” symbol, and “Red 7” symbol in order from the left on the active line, a replay privilege is given and the gaming state is the first as the second replay prize. Transition to a replay time state (hereinafter referred to as “first RT state”). Similarly, in the case of stopping alongside the “replay” symbol, “replay” symbol, and “white 7” symbol in order from the left on the active line, a replay privilege is given and a gaming state as the third replay prize Shifts to the second replay time state (hereinafter referred to as “second RT state”).

  Hereinafter, a combination of symbols corresponding to each winning prize is also referred to as a winning symbol combination. For example, the combination of the second replay symbol is a combination of symbols for the second replay winning, that is, a combination of “Replay” symbol, “Replay” symbol, and “Red 7” symbol. The symbols of the reels 32L, 32M, and 32R corresponding to the winnings are also referred to as winning symbols. For example, the second replay symbol is a “replay” symbol for the left reel 32L and the middle reel 32M, and a “red 7” symbol for the right reel 32R.

  On the lower left side of the game panel 25, a start lever 41 that is operated to start rotation of the reels 32L, 32M, and 32R is provided. The start lever 41 constitutes start operation means or start operation means operated to start rotation of the reels 32L, 32M, and 32R, that is, to start variable display of symbols.

  On the right side of the start lever 41, button-like stop switches 42 to 44 that are operated to individually stop the rotating reels 32L, 32M, and 32R are provided. Each of the stop switches 42 to 44 is disposed immediately below the display windows 26L, 26M, and 26R corresponding to the reels 32L, 32M, and 32R to be stopped. That is, when the left stop switch 42 is operated, the rotation of the left reel 32L is stopped. When the middle stop switch 43 is operated, the rotation of the middle reel 32M is stopped and the right stop switch 44 is operated. In this case, the rotation of the right reel 32R is stopped. The stop switches 42 to 44 constitute stop operation means operated to stop the variable display of symbols based on the rotation of the reels 32L, 32M, 32R.

  On the lower right side of the display windows 26L, 26M, 26R, a medal insertion slot 45 for inserting medals is provided. The medal slot 45 constitutes an input means for inputting game media. If attention is paid to the point that the medal insertion slot 45 is directly inserted by the player, it can be said that it constitutes a direct input means for directly inputting the game medium.

  The medals inserted from the medal insertion slot 45 are guided to either the storage passage 47 or the discharge passage 48 by a selector 46 as passage switching means provided on the back surface of the front door 12. More specifically, the selector 46 is provided with a medal path switching solenoid 46a. When the medal path switching solenoid 46a is not excited, the medal is guided to the discharge path 48, and when the medal path switching solenoid 46a is excited, the medal is switched. Is guided to the storage passage 47 side. The medal guided to the storage passage 47 is guided to the hopper device 51 housed inside the housing 11. On the other hand, the medal guided to the discharge passage 48 is guided to the medal tray 50 from the medal discharge port 49 provided in the lower front portion of the front door 12 and returned to the player.

  The hopper device 51 includes a storage tank 52 that stores medals and a payout device 53 that pays out medals to a player. The payout device 53 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 48 a provided in the discharge passage 48 and to pay out the medal to the medal tray 50 through the discharge passage 48. It has become. Further, a reserve tank 54 is provided on the right side of the hopper device 51 to avoid storing a predetermined amount or more of medals in the storage tank 52. Inside the storage tank 52 of the hopper device 51, a guide plate 52a for discharging medals from the storage tank 52 to the reserve tank 54 is provided. Therefore, when medals are stored more than the height at which the guide plate 52 a is provided, the medals are stored in the reserve tank 54.

  A button-like return switch 55 is provided below the medal slot 45. When the return switch 55 is operated in a situation where a medal inserted into the medal insertion slot 45 is jammed in the selector 46, the selector 46 is mechanically operated so that the medal jammed in the selector 46 becomes a medal. It is returned from the discharge port 49.

  On the lower left side of the display windows 26L, 26M, 26R, there is provided a first credit insertion switch 56 for inserting three credited virtual medals as game media at a time. Further, a second credit insertion switch 57 and a third credit insertion switch 58 are provided on the left side of the first credit insertion switch 56. The second credit insertion switch 57 is for inserting two virtual medals at a time, and the third credit insertion switch 58 is for inserting one virtual medal. Each of the credit insertion switches 56 to 58 constitutes input means for inputting a game medium together with the medal insertion slot 45. It should be noted that the medal insertion slot 45 is accompanied by an operation of directly inserting a medal by the player, whereas each of the credit insertion switches 56 to 58 is only accompanied by an operation of inserting a virtual medal based on the storage memory. In other words, it can be said to constitute indirect input means for indirectly inputting game media.

  A settlement switch 59 is provided on the left side of the start lever 41. In other words, the slot machine 10 has a credit function for storing and storing surplus inserted medals up to a predetermined maximum value (for 50 medals) and payout medals at the time of winning as virtual medals. When the settlement switch 59 is operated under the stored and stored condition, the virtual medal is paid out from the medal discharge port 49 as an actual medal. In this case, if paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the checkout switch 59 constitutes a checkout operation means for actually paying out the stored game media.

  Below the display windows 26L, 26M, and 26R of the game panel 25, a credit display unit 60 that displays the number of virtual medals credited, and a remaining payout number that displays the number of remaining medals to be paid out before the BB state ends. A display unit 61 and a payout number display unit 62 for displaying the number of medals paid out at the time of winning are provided. Although these display parts 60-62 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, the relationship between the bet number of medals and the activated combination lines will be described with reference to FIG. If a medal is inserted from the medal slot 45 at the start of the game, a bet is placed.

  When the first medal is inserted into the medal slot 45, the bet number is 1, and the middle line L2 is activated. When the second medal is inserted into the medal insertion slot 45, the number of bets becomes 2, and a total of three combination lines including the upper line L1 and the lower line L3 in addition to the middle line L2 are activated. When the third medal is inserted into the medal insertion slot 45, the number of bets becomes 3, and all the combination lines L1 to L5 are activated.

  When four or more medals are inserted into the medal insertion slot 45, if the number of virtual medals stored and stored at that time is less than 50, the surplus medals exceeding three are stored in the slot machine 10. Then, the number of virtual medals on the credit display unit 60 is added and displayed. On the other hand, when the number of virtual medals is 50 or reaches 50, the selector 46 switches from the storage passage 47 to the discharge passage 48, and the surplus medals are returned from the medal discharge port 49 to the medal tray 50. Is done.

  Further, virtual medals are stored and stored, and when any of the first to third credit insertion switches 56 to 58 is operated at the start of the game, the virtual medals are inserted and a bet is made. When any of the first to third credit insertion switches 56 to 58 is operated, the number of virtual medals displayed on the credit display unit 60 is subtracted by the number of inserted virtual medals. Is the same as the case where a medal is inserted from the medal insertion slot 45, and the description is omitted.

  Incidentally, when any of the first to third credit insertion switches 56 to 58 is operated and the virtual medal to be inserted is not stored and stored, for example, when the display of the credit display unit 60 is 2, the first For example, when the credit insertion switch 56 is operated, all the numerical values in the credit display unit 60 are subtracted to 0, and a bet is made for the amount of virtual medals that can be inserted.

  The upper part of the front door 12 has an upper lamp 63 that lights up or flashes as the game progresses, and a pair of left and right sounds that produce various sound effects as the game progresses and inform the player of the gaming state. Speaker 64 and an auxiliary display unit 65 for giving various information to the player. The auxiliary display unit 65 is for executing various display effects as the game progresses, and it can be considered that the game by each reel 32L, 32M, 32R is caused by the main display unit. This is referred to as an auxiliary display unit 65. A display control device 81 for driving the upper lamp 63, the speaker 64, and the auxiliary display unit 65 is provided on the back surface of the auxiliary display unit 65.

  A power supply box 70 is provided on the left side of the hopper device 51 inside the housing 11. The power supply box 70 accommodates a power supply device 91 therein, and includes a power switch 71, a reset switch 72, a setting key insertion hole 73, and the like. The power switch 71 is a start switch for supplying power to each unit including the main controller 101. The reset switch 72 is a switch for resetting an error state of the slot machine 10. Further, the setting key insertion hole 73 is used by a hole manager or the like to adjust the appearance of medals. That is, the hall manager or the like can set the winning probability of the slot machine 10 by inserting the setting key into the setting key insertion hole 73 and turning it ON. The reset switch 72 is operated not only when the error state is reset but also when the winning probability of the slot machine 10 is changed.

  Above the reel unit 31, a main control device 101 that manages and manages games is attached to the housing 11.

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main control device 101 is equipped with a microcomputer centering on a CPU 102 which is an arithmetic processing means. In addition to the power supply device 91, a clock circuit 103 that outputs a rectangular wave with a predetermined frequency, an input / output port 104, and the like are connected to the CPU 102 via an internal bus. The main control device 101 functions as a main board built in the slot machine 10.

  On the input side of the main controller 101, a reel unit 31 (more specifically, a reel index sensor that individually detects that each of the reels 32L, 32M, and 32R has made one rotation) and a start detection sensor that detects an operation of the start lever 41 are provided. 41a, stop detection sensors 42a to 44a that individually detect the operation of each of the stop switches 42 to 44, a inserted medal detection sensor 45a that detects a medal inserted from the medal slot 45, and a medal paid out from the hopper device 51. Payout detection sensor 51a, credit insertion detection sensors 56a-58a that individually detect the operation of each credit insertion switch 56-58, settlement detection sensor 59a that detects the operation of the settlement switch 59, and reset detection that detects the operation of the reset switch 72 Sensor 72a, setting key insertion hole 7 Various sensors such as a setting key detection sensor 73a for detecting that the setting key is inserted and turned ON are connected, and signals from these various sensors are output to the CPU 102 via the input / output port 104. It has become.

  A power supply device 91 is connected to the input side of the main control device 101 via an input / output port 104. The power supply device 91 includes a power supply unit 91a that supplies driving power to the electronic devices of the slot machine 10 including the main control device 101, a power failure monitoring circuit 91b, and the like.

  The power failure monitoring circuit 91b monitors the power-off state and generates a power failure signal not only at the time of power failure but also when the power switch 71 powers off. For this reason, the power failure monitoring circuit 91b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 91a, and determines that the power supply has been shut off when this drive voltage drops below, for example, 10 volts. Power outage signal is output. The power failure signal is supplied to each of the CPU 102 and the input / output port 104. The CPU 102 recognizes this power failure signal and executes a power failure process described later. The power failure signal is also supplied to the display control device 81.

  The power supply unit 91a is configured to output a stabilized voltage of 5 volts that is used as a drive voltage in a control system such as the main controller 101 even when the output voltage drops below 10 volts. As a time for outputting the stabilization voltage, a time sufficient for executing the power failure process by the main controller 101 is secured.

  On the output side of the main controller 101, a reel unit 31 (more specifically, a stepping motor for rotating the reels 32L, 32M, and 32R), a medal path switching solenoid 46a provided in the selector 46, a hopper device 51, a credit A display unit 60, a remaining payout number display unit 61, a payout number display unit 62, a display control device 81, an external concentrated terminal board 121 that can transmit information to a hall management device (not shown), etc. Yes.

  The display control device 81 is a control device for driving the upper lamp 63, the speaker 64, and the auxiliary display unit 65, and includes a substrate on which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving a signal from the main controller 101, the display controller 81 independently controls the upper lamp 63, the speaker 64, and the auxiliary display unit 65. Therefore, the display control device 81 is a sub-base for executing auxiliary control in relation to the main control device 101 which is a main base for overall management of games. Various display units 60 to 62 may be configured to be driven and controlled by the display control device 81.

  The CPU 102 described above includes a ROM 105 that stores various control programs executed by the CPU 102 and fixed value data, and a work area that temporarily stores various data when executing the control programs stored in the ROM 105. In addition to the RAM 106 for assuring, as is well known, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, a data transmission / reception circuit, a credit counter for counting the number of credits, etc. Various counters are built-in. The ROM 105 and the RAM 106 constitute a main memory as storage means, and a program for executing various processes shown in the flowcharts of FIG. 10 and subsequent figures is stored in the ROM 105 described above as a part of the control program.

  The RAM 106 is configured to retain (backup) data by being supplied with a backup voltage from the power supply device 91 even after the power to the slot machine 10 is cut off. In the RAM 106, a memory for temporarily storing various data, a winning flag storage area 106a for storing a lottery result of a combination, and a sliding table used when stop control of each reel 32L, 32M, 32R is performed. In addition to the sliding table storage area 106b for storing the game information, the status information storage area 106c for storing the gaming status such as the BB status, etc., a backup area is provided.

  The backup area is an area for storing the value of the stack pointer when the power is shut down due to the occurrence of a power failure or the like (including power shutdown by operating the power switch 71; the same applies hereinafter). Yes, when the power failure is resolved (including power-on by operating the power switch 71; the same applies hereinafter), the state of the slot machine 10 can be restored to the state before power-off based on the backup area information. . Writing to the backup area is executed when the power is shut off by the power failure process (see FIG. 10), and the restoration of each value written to the backup area is executed in the main process when the power is turned on.

  Further, a power failure signal from the power failure monitoring circuit 91b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 102 when the power is shut down due to the occurrence of a power failure or the like. When the power is shut off, an NMI interrupt process as a power failure flag generation process is immediately executed.

  Next, each control process executed by the CPU 102 of the main control apparatus 101 will be described. The processing of the CPU 102 can be broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and a power failure signal to the NMI terminal. NMI interrupt processing that is activated in response to the input of. In the following, a process related to the progress of the game, that is, a timer interrupt process and a normal process performed in the main process will be described with reference to the flowcharts of FIGS.

  FIG. 10 is a flowchart of a timer interrupt process periodically executed by the main control apparatus 101. A timer interrupt is generated every 1.49 msec by the CPU 102 of the main control apparatus 101, for example.

  First, in the register saving process shown in step S101, the values of all the registers in the CPU 102 used in the normal process described later are saved in the backup area of the RAM 106. In step S102, it is confirmed whether or not a power failure flag is set. If the power failure flag is set, the process proceeds to step S103, and a power failure process is executed.

  Here, an outline of the power failure process will be described.

  When the power is shut off due to the occurrence of a power failure or the like, a power failure signal is output from the power failure monitoring circuit 91b of the power supply device 91, and the power failure signal is input to the main controller 101 via the NMI terminal. When a power failure signal is input, main controller 101 immediately executes NMI interrupt processing and sets a power failure flag in the power failure flag storage area provided in RAM 106.

  In the power failure process, it is first determined whether or not the command transmission has been completed. If the transmission has not been completed, this process is terminated and the process returns to the timer interrupt process to terminate the command transmission. If the command transmission has been completed, the value of the stack pointer of the CPU 102 is stored in the backup area of the RAM 106. Thereafter, the output state of the output port in the input / output port 104 is cleared, and all actuators (not shown) are turned off. Then, a RAM determination value for determining whether or not the data in the RAM 106 is normal when the power failure is eliminated is stored in the backup area, thereby prohibiting subsequent RAM access. After performing the above processing, an infinite loop is entered in preparation for the case where the power supply is completely shut down and the processing cannot be executed. In consideration of, for example, the case where the power failure flag is set erroneously due to noise or the like, it is confirmed whether or not a power failure signal is output until the infinite loop is entered. If the power failure signal is not output, the power failure state is recovered, so that writing to the RAM 106 is permitted, the power failure flag is reset, and the process returns to the timer interrupt process. If the power outage signal is continuously output, the infinite loop is entered. Incidentally, it is confirmed whether or not a power failure signal is output even under an infinite loop, and when the power failure signal is not output, the main processing is performed.

  Returning to the description of the timer interrupt process, if the power failure flag is not set in step S102, various processes after step S104 are performed.

  That is, in step S104, a watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S105, an interrupt end declaration process is performed so that the next timer interrupt can be set for the CPU 102 itself. In step S106, in order to rotate each reel 32L, 32M, 32R, a stepping motor control process for driving a stepping motor that is a respective rotating drum driving motor is performed. In step S107, the states of various sensors (see FIG. 9) such as the stop detection sensors 42a to 44a, the inserted medal detection sensor 45a, and the payout detection sensor 51a connected to the input / output port 104 are read, and whether the read result is normal. A sensor monitoring process for monitoring the above is performed. In step S108, timer calculation processing for subtracting the value of each counter or timer is performed. In step S109, a counter process for outputting the result of counting the number of medals bet and the number of payouts to the external concentration terminal board 121 is performed.

  In step S110, command output processing for transmitting various commands such as a lottery result command to be described later to the display control device 81 is performed. In step S111, a segment data setting process for setting segment data displayed on the credit display unit 60, the remaining payout number display unit 61, and the payout number display unit 62 is performed. In step S112, segment data display processing is performed in which the segment data set in the segment data setting processing is supplied to the display units 60 to 62 to display corresponding numbers, symbols, and the like. In step S113, port output processing for outputting data corresponding to the I / O device from the input / output port 104 is performed. In step S114, the value of each register saved in the backup area in the previous step S101 is returned to the corresponding register in the CPU 102, respectively. Thereafter, in step S115, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  Next, normal processing for performing main control related to the game will be described based on the flowchart of FIG.

  First, in step S201, an interrupt permission process for permitting the next timer interrupt is performed. In step S202, pre-start processing for enabling a game is performed. In the pre-start process, the process waits until the display control device 81 and the like finish initialization. When the initialization of the display control device 81 or the like is completed, the game management process shown in steps S203 to S212 is performed.

  As a game management process, in step S203, data such as various game information stored in the RAM 106 (for example, a random value used in the previous game) is cleared. Thereafter, in step S204, start waiting processing is performed.

  In the start waiting process, it is determined whether any of the first to third re-game winnings is established in the previous game. If any of the re-game winnings has been established, an automatic insertion process for automatically inserting the same number of virtual medals as the previous bet number is performed, and the start waiting process is terminated. In the automatic insertion process, virtual medals are inserted without reducing the number of virtual medals displayed on the credit display unit 60. That is, if any re-game winning is established in the previous game, the player can play the current game without reducing the number of medals owned and without inserting medals. If none of the re-game winnings have been established, a sensor abnormality confirmation process is performed to confirm whether an abnormality has occurred in the sensor reading result performed in the sensor monitoring process step S107 of the timer interruption process, If an abnormality has occurred, the slot machine 10 is put into an error state and an abnormality occurrence process for notifying the occurrence of the error is performed. Such an error state is maintained until the reset switch 72 is operated. If the sensor reading result is normal, it is determined whether or not the settlement switch 59 has been operated. If the settlement switch 59 has been operated, a medal return process for paying out the same number of medals as the credited virtual medal I do. After completion of the medal return process or when the settlement switch 59 is not operated, whether or not the medal insertion or the credit insertion switches 56 to 58 are operated between the previous start waiting process and the current start waiting process If either one is performed, a medal insertion process for setting an effective line or the like is performed, and the start waiting process is terminated. If neither medal insertion nor operation of the credit insertion switches 56 to 58 is performed between the previous start waiting process and the current start waiting process, the start waiting process is ended as it is.

  After completion of the start waiting process, it is determined in step S205 whether or not the bet number of medals has reached a specified number (3 in the present embodiment). If the bet number has not reached the specified number, step S204 is performed. Returning to the start waiting process, the process after the sensor abnormality confirmation process is performed. If the bet number has reached the specified number, it is determined in step S206 whether or not the start lever 41 has been operated. When the start lever 41 is not operated, the process returns to the start waiting process of step S204, and the processes after the sensor abnormality confirmation process are performed among the processes.

  On the other hand, when the start lever 41 is operated, the game can be started when the start lever 41 is operated in a situation where a prescribed number of medals are betted. Means that a command has occurred. In such a case, the process proceeds to step S207, and the medal path switching solenoid 46a is switched to a non-excited state to prohibit bet acceptance. Thereafter, the lottery process in step S208, the reel control process in step S209, the medal payout process in step S210, the RT state process in step S211 and the BB state process in step S212 are executed in order, and the process returns to step S203.

  Next, the lottery process in step S208 will be described based on the flowchart of FIG.

  In step S301, a random number used when determining whether or not the combination is correct is acquired. In the slot machine 10, when the start lever 41 is operated, the hardware circuit latches the value of the free-run counter at that time. The free-run counter generates random numbers from 0 to 65535, and after confirming the operation of the start lever 41, the CPU 102 stores the value latched by the hardware circuit in the RAM 106. By adopting such a configuration, it is possible to quickly acquire a random number at the timing when the start lever 41 is operated, and it is possible to avoid occurrence of problems such as synchronization. The hardware circuit of the slot machine 10 is configured to latch the value of the free run counter each time the start lever 41 is operated.

  After acquiring the random number, in step S302, a lottery table for determining whether or not the winning combination is selected is selected. Specifically, the current gaming state of the slot machine 10 is determined, and a lottery table corresponding to the gaming state is selected. The slot machine 10 is roughly divided into five game states, namely, a normal state, a BB state, an RT preparation state, a first RT state, and a second RT state, and a lottery table corresponding to each game state is selected. Here, in this slot machine 10, six-stage winning probabilities from “Setting 1” to “Setting 6” are prepared in advance, the setting key is inserted into the setting key insertion hole, and the ON operation is performed and a predetermined operation is performed. By performing, it is possible to set which winning probability is to execute the internal processing. In step S302, the lottery table with the lowest expected value of medal payout is selected when the setting state is “setting 1”, and the lottery table with the highest expected value of medal payout is selected when it is “setting 6”.

  The lottery table will be briefly described. FIG. 13 is a normal state lottery table selected in the normal state of “setting 3”. In the lottery table, the same number of index values IV as the number of combinations to be determined are set. Each index value IV is uniquely associated with each winning combination, and a point value PV is set. ing. That is, in the normal state in the slot machine 10, the determination is made for six types of combinations of the first replay, the bell, the watermelon, the cherry, the single combination, and the BB, and the two types of the second replay and the third replay are performed. Judgment is not made for the role of.

  After selecting the lottery table, the index value IV is set to 1 in step S303, and a determination value DV used for determining whether or not the winning combination is determined is set in subsequent step S304. In the determination value setting process, a new determination value DV is set by adding a point value PV corresponding to the current index value IV to the current determination value DV. In the initial determination value setting process, the random value acquired in step S301 is set as the current determination value DV, and a new point value PV corresponding to 1 as the current index value IV is added to the random value. The determination value is DV.

  Thereafter, in step S305, whether or not the combination corresponding to the index value IV is determined. In the combination determination, it is determined whether or not the determination value DV exceeds 65535. If 65535 is exceeded, the process proceeds to step S306, and the winning flag of the combination corresponding to the index value IV at that time is set in the winning flag storage area 106a of the RAM 106. For example, when the determination value DV exceeds 65535 when IV = 3, in step S306, the watermelon winning flag is set in the winning flag storage area 106a.

  By the way, if the set winning flag is one of the first replay winning flag, the bell winning flag, the watermelon winning flag, the cherry winning flag, or the one-piece winning flag, the corresponding winning flag is set. It is reset after the game is over (see S203 of the normal process). On the other hand, when the winning flag is the BB winning flag, the BB winning flag is reset as one of the conditions that the BB winning is established. That is, the BB winning flag may be valid for a plurality of games. In step S306 in the state where the BB winning flag is carried over, if the current index value IV is 1 to 5, the winning flag corresponding to the index value IV is set, and if the current index value IV is 6, BB winning is made. Do not set the flag. In other words, in a game in which the BB winning flag is carried over, if one of the first replay, the bell, the watermelon, the cherry, or the single player is won, the corresponding winning flag is set, while the BB is won. Does not set the BB winning flag.

  If the determination value DV does not exceed 65535 in step S305, it means that the combination corresponding to the index value IV is lost. In such a case, 1 is added to the index value IV in step S307, and in the subsequent step S308, it is determined whether or not there is a combination corresponding to the index value IV, that is, whether or not there is a determination target to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index values IV set in the lottery table. If there is a determination target to be determined whether or not, the process returns to step S304 and the determination of whether or not the winning combination is continued. At this time, in step S304, a point value PV corresponding to the current index value IV is added to the determination value DV (that is, the current determination value DV) used for determining whether or not the previous winning combination is a new determination value DV. In step S305, whether or not a winning combination is made is determined based on the determination value DV. Incidentally, in the case of determining whether or not a winning combination is made using the lottery table shown in FIG. 13, the winning probability of BB is about 1/200, the winning probability of the first replay is about 7.30, and the winning of the bell The probability is about 10.9, the watermelon winning probability is 1/128, the cherry winning probability is about 73.0 / 1, and the winning combination of 1 sheet is 1/128. In addition, the probability of losing no winning combination is about 1.36.

  After the winning flag is set in step S306, or when it is determined in step S308 that there is no determination target to be determined, it means that the winning combination determination has ended. In such a case, a lottery result command is set in step S309. Here, the lottery result command is a command that is transmitted to the display control device 81 in order to grasp the result of the combination determination. By receiving the lottery result command, the display control device 81 executes drive control of the upper lamp 63 and the auxiliary display unit 65 to suggest a winning combination, for example. However, in the normal process, various commands such as the lottery result command are only set in the ring buffer, and the command is not transmitted to the display control device 81. The command transmission to the display control device 81 is performed in the command output process S110 of the timer interrupt process described above.

  In step S310, a slip table setting process for setting a reel table (stop table) for reel stop control is performed, and the lottery process is terminated. Here, the slip table is a table in which it is determined how much the reels 32L, 32M, and 32R are slid (rotated) and stopped from the timing when the stop switches 42 to 44 are operated. In other words, the slip table is a symbol that has reached the base point position (lower stage in the present embodiment) when the stop switches 42 to 44 are pressed, and actually stops at the base point position. This is a stop data group from which a relationship with a stop symbol (stop symbol number) can be derived.

  In the slot machine 10, as a stop mode for stopping the reels 32L, 32M, and 32R, when the stop switches 42 to 44 are operated, a stop mode for stopping the reaching symbol reaching the base position as it is is supported. Stop mode for stopping the reel to be slid after one symbol, Stop mode for stopping after sliding for two symbols, Stop mode for stopping after sliding for three symbols, Stop after sliding for four symbols There are prepared five patterns of stop modes. Then, a plurality of sliding tables each having one of the five patterns of stop modes set for each symbol number of each reel 32L, 32M, 32R are prepared for each combination.

  Thus, by setting the sliding table so that each reel 32L, 32M, 32R stops from when the stop switches 42 to 44 are operated until the specified time (190 msec) elapses, the display window 26L, It is possible to give the player an impression as if the symbol arrangement (hereinafter referred to as stop appearance) that stops within the range that can be visually recognized from 26M and 26R is determined by the player's operation. In addition, by making it possible to slide up to 4 symbols, it becomes possible to stop combinations of symbols corresponding to the winning combination in the lottery on the active line as much as possible within the specified time. At the same time, it is possible to prevent the combination of symbols corresponding to the combination not won in the lottery from stopping on the active line.

  FIG. 14 is an example of a sliding table that is set when the “replay” symbol of the left reel 32L is stopped on the active line. The symbol having the number of slips of 0 is a symbol that actually stops in the lower stage. For example, if the left stop switch 42 is operated while the 14th “watermelon” symbol of the left reel 32L reaches the lower stage, the left reel 32L stops without slipping and the 16th “replay” symbol. Stops at the top. In addition, a symbol whose number is not zero means that the reel slides by the number of symbols described. For example, if the left stop switch 42 is operated while the 8th “bell” symbol of the left reel 32L has reached the lower stage, the left reel 32L slides by 4 symbols and the 12th “replay” symbol is displayed. Stop at the bottom. As described above, in the slip table, the number of slips when the stop switches 42 to 44 are operated at the timing when the symbols attached to the reels 32L, 32M, and 32R reach the lower stage is set for each symbol number.

  In the smooth table setting process, the winning flag set in the winning flag storage area 106a of the RAM 106 is confirmed, and the smooth table uniquely corresponding to the set winning flag is stored in the smooth table storing area 106b of the RAM 106. set. At this time, in the slot machine 10, the middle reel 32 </ b> M and the right reel 32 </ b> R so that the symbol corresponding to the winning combination of the left reel 32 </ b> L (hereinafter referred to as “winning symbol”) stops at either the upper or lower level. Set the sliding table set so that the winning symbol of stops at the middle. Here, setting the sliding table set so that the winning symbol of the left reel 32L stops at either the upper stage or the lower stage generally rotates in the order of the left reel 32L → the middle reel 32M → the right reel 32R. This is to diversify the stop output in consideration that the stop switches 42 to 44 are operated to stop the operation.

  Here, the symbol arrangement of each reel 32L, 32M, 32R will be briefly described.

  The “replay” symbol is arranged on each of the reels 32L, 32M, and 32R so that the interval between the symbol that reaches the lower stage first and the symbol that reaches the next is 4 symbols or less. For example, the 4th “replay” symbol and the 7th “replay” symbol of the left reel 32L are arranged so that the interval is 2 symbols, and the 1st “replay” symbol of the middle reel 32M and 6 The “replay” symbols of the numbers are arranged so that the interval is 4 symbols. As described above, the “replay” symbols are arranged on the reels 32L, 32M, and 32R so that the interval between the symbols of the same type is 4 symbols or less. As described above, the reels 32L, 32M, and 32R can be stopped after sliding up to four symbols at the timing when the stop switches 42 to 44 are operated. Therefore, with such a symbol arrangement, the “replay” symbol can be stopped at an arbitrary position when the first replay prize is established, regardless of the timing at which the stop switches 42 to 44 are operated. Can do. For example, when the middle stop switch 43 is operated when the first “replay” symbol of the middle reel 32M reaches the lower level, the “replay” symbol can be stopped at the lower level if the middle reel 32M is stopped as it is. If the middle reel 32M is slid after 3 symbols and then stopped, No. 6 "Replay" symbol can be stopped at the upper stage, and if the middle reel 32M is slid after 4 symbols and then stopped, No. 6 The “replay” symbol can be stopped in the middle.

  In the slot machine 10, in addition to the “replay” symbols, the “bell” symbols are also arranged on the reels 32 </ b> L, 32 </ b> M, and 32 </ b> R so that the intervals between the same symbols are 4 symbols or less. For this reason, even if the stop switches 42 to 44 are operated at any timing, the “bell” symbol can be stopped at an arbitrary position when the bell winning is established.

  On the other hand, the “watermelon” symbols are not arranged on the reels 32L, 32M, and 32R so that the interval between the symbols of the same type is 4 symbols or less. For this reason, for example, when the left stop switch 42 is operated when the third “red 7” symbol of the left reel 32L has reached the lower stage, even if the left reel 32L is slid by four symbols, the “watermelon” The symbol cannot be stopped on the active line. Therefore, even if the watermelon is won and the slide table set so that the “watermelon” symbol stops on the active line is set, depending on the timing of operation of the stop switches 42 to 44, “watermelon” There is a case where a symbol does not stop on the active line and a so-called spillover occurs in which a watermelon winning is not established. In the slot machine 10, in addition to the “watermelon” symbol, the “red 7” symbol is also arranged on each reel 32 </ b> L, 32 </ b> M, 32 </ b> R so that a section separated by 5 symbols or more is formed. Further, in the left reel 32L, the “cherry” symbols are arranged so as to form a section separated by 5 symbols or more, and in the middle reel 32M, the “youth” symbols form a section separated by 5 symbols or more. In the right reel 32R, the “white 7” symbols are arranged so as to form a section separated by 5 symbols or more. For this reason, when any one of BB, watermelon, cherry, and one winning combination is won, it is necessary to operate the stop switches 42 to 44 so as to stop the winning symbol on the active line.

  Returning to the description of the smooth table setting process, when the BB winning flag and other winning flags are set, the following smooth table is set.

  When the BB winning flag and the first regame winning flag are set, the first regame winning slide table for preferentially establishing the first regame winning is set. In the first replay winning slide table, the "replay" symbol of the middle reel 32M and the right reel 32R is prioritized and stopped so that the "replay" symbol of the left reel 32L is prioritized and stopped in the upper or lower stage. It is set to be.

  When the BB winning flag and the small role winning flag (that is, any one of the bell winning flag, the watermelon winning flag, the cherry winning flag, and the one-sheet winning flag) are set, the BB for preferentially establishing the BB winning. Set the priority winning slide table. However, the “Red 7” symbol, which is the BB symbol, is arranged on each of the reels 32L, 32M, 32R so as to form a section separated by five symbols or more as described above. May not be able to stop the “Red 7” symbol on the active line. Therefore, in the BB priority winning slide table, the reels 32L, 32M, and 32R are set as follows. For the left reel 32L, if it is possible to stop both the “red 7” symbol and the winning small role symbol on the active line, “red 7” so that both symbols are preferentially stopped on the active line. It is impossible to stop the “Red 7” symbol at the upper or lower level, so that if the symbol can be stopped at either the upper level or the lower level, it will be impossible to stop the symbol. If it is possible to stop at each position, the winning small role symbol is set to stop at each position. The middle reel 32M and the right reel 32R are set so that the “red 7” symbol is stopped preferentially if possible, and the “red 7” symbol is placed at each position. If it is impossible to stop and the winning small symbol can be stopped at each position, the winning small symbol is set to stop at each position.

  Next, the reel control processing in step S209 will be described based on the flowchart of FIG.

  In the reel control process, first, a rotation start process for starting the rotation of each of the reels 32L, 32M, and 32R is performed in step S401.

  In the rotation start process, it is checked whether or not a predetermined wait time (for example, 4.1 seconds) has elapsed since the reel started to rotate in the previous game. Wait until When the wait time has elapsed, a wait time for the next game is reset, and a motor control initialization process for setting rotation start information in the motor control storage area provided in the RAM 106 is performed. By performing such processing, stepping motor acceleration processing is started in stepping motor control processing S106 of timer interruption processing, and the reels 32L, 32M, and 32R start to rotate. For this reason, even if the player bets a specified number of medals and operates the start lever 41, the reels 32L, 32M, and 32R may not immediately start rotating. Thereafter, the process waits until the reels 32L, 32M, and 32R rotate at a constant rotation speed at a predetermined rotation speed, and the rotation start process ends. In addition, when the rotation speed of each of the reels 32L, 32M, and 32R becomes a constant speed, the CPU 102 can generate a stop command by lighting up lamps (not shown) of the stop switches 42 to 44. Is notified to a player or the like.

  Following the rotation start process, a stop pre-process is performed in step S402.

  In the pre-stop process, as shown in the flowchart of FIG. 16, first, in step S501, it is determined whether any of the stop switches 42 to 44 has been operated. When none of the stop switches 42 to 44 is operated, the process waits until any of the stop switches 42 to 44 is operated. If it is determined that any of the stop switches 42 to 44 has been operated, the process proceeds to step S502, where it is determined whether or not the stop switch corresponding to the rotating reel has been operated, that is, whether or not a stop command has been issued. To do. If no stop command has been issued, the process returns to step S501 and waits until any of the stop switches 42 to 44 is operated. When the stop command is generated, the process proceeds to step S503, and it is determined whether or not the current stop command is the third stop command, that is, whether or not the stop switch is operated when only one reel is rotating. . If the current stop command is the third stop command, an affirmative determination is made in step S503, and the pre-stop processing ends. On the other hand, in the case of the first stop command that is generated when all the reels 32L, 32M, and 32R are rotating, or the second stop command that is generated when two reels are rotating, negative in step S503. In addition to making the determination, the first change process of the slip table is performed in step S504, and the pre-stop process is terminated.

  Here, the first change process of the slide table is a process of changing the slide table stored in the slide table storage area 106b of the RAM 106 before stopping the reel corresponding to the stop command. In the first change process of the slide table, it is assumed that the slide table is set in the slide table storage area 106b, for example, when the first stop command is generated by operating the stop switches 43 and 44 other than the left stop switch 42. When the stop switches 42 to 44 are operated in an operation order different from the operation order of the stop switches 42 to 44, the sliding table is changed. By performing such a process, it is possible to diversify the stopping points, and to reduce the frequency of occurrence of so-called missing where a winning corresponding to the set winning flag is not established.

  Returning to the description of the reel control process, when the pre-stop process is completed in step S402, it means that a stop switch corresponding to the rotating reel is operated to advance the game, and a stop command is generated. In such a case, stop control processing shown in steps S403 to S409 is performed to stop the rotating reel.

  That is, in step S403, the symbol number of the reaching symbol reaching the lower stage at the timing when the stop switch is operated is confirmed. Specifically, the symbol number of the reaching symbol reaching the lower stage is confirmed by the number of excitation pulses output from the time when the detection signal of the reel index sensor is input. In subsequent step S404, the number of slips of the reel to be stopped this time is calculated from the data of the symbol number corresponding to the reaching symbol among the slip tables set in the slip table storage area 106b. Thereafter, in step S405, the calculated number of slips is added to the symbol number of the reaching symbol, and the symbol number of the stop symbol that is actually stopped at the lower stage is determined. In step S406, it is determined whether or not the symbol number of the reaching symbol of the reel to be stopped this time is equal to the symbol number of the stop symbol. If they are equal, a reel stop process for stopping the rotation of the reel is performed in step S407. Do. Thereafter, in step S408, it is determined whether or not all the reels 32L, 32M, and 32R are stopped. If all the reels 32L, 32M, 32R are not stopped, the slide table second change process is performed in step S409, and the process returns to the pre-stop process in step S402.

  Here, the second change process of the slide table is a process of changing the slide table stored in the slide table storage area 106b of the RAM 106 after the reels are stopped. In the second change process of the slide table, the slide table is changed based on the set winning flag and the stoppage of the stopped reel. For example, when the bell winning flag is set and the “bell” symbol of the left reel 32L is stopped at the upper stage, the “bell” symbol of the middle reel 32M is changed to a slip table set to stop at the upper or middle stage. By performing such a process, it is possible to diversify the reel stop appearances to be stopped later according to the result of the reel stop, and to reduce the frequency of occurrence of missing.

  On the other hand, if it is determined in step S408 that all the reels 32L, 32M, and 32R are stopped, a payout determination process is performed in step S410, and this process ends. The payout determination process is a process of setting the number of medals to be paid out as one of the conditions that a combination of winning symbols is arranged on an active line.

  In the payout determination process, a combination of symbols formed on each active line is derived from the symbol number of the stopped symbol stopped at the lower stage of each reel 32L, 32M, 32R, and whether or not a winning is achieved on the effective line. Determine. If a winning combination has been established, it is further determined whether or not the winning combination matches the winning flag set in the winning flag storage area 106a. If the winning combination combination matches the winning flag, the winning combination combination and the number of payouts corresponding to the winning combination combination are set in the payout information storage area provided in the RAM 106. On the other hand, if the winning combination does not match the winning flag, an abnormality occurrence process for notifying the occurrence of the error is performed while the slot machine 10 is in an error state. Such an error state is maintained until the reset switch 72 is operated. When the payout determination is completed for all the active lines, the payout determination process is ended.

  Next, the outline of the medal payout process in step S210 will be described.

  In the medal payout process, it is determined whether or not the payout number set in the payout information storage area is zero. When the number of payouts is 0, it means that it has been determined in the previous payout determination process that a winning for paying out medals has not been established. In such a case, it is determined whether or not the first re-game winning has been established based on the winning combination set in the payout determination processing. If the first regame winning is not established, the medal payout process is terminated as it is. If the first regame winning is established, a regame setting process is performed for setting the gaming state to the replaying state. The medal payout process is terminated. In the start waiting process S204 described above, an automatic insertion process is performed when it is determined that the current gaming state is the re-gaming state.

  On the other hand, if the number of payouts set in the payout information storage area is not 0, the same number of medals are paid out, and the medal payout process is terminated. Specifically, regarding the payout of medals, when the count value of the credit counter has not reached the upper limit (the number of stored medals is 50), the payout number is added to the count value of the credit counter and the value after the addition is added. It is displayed on the credit display unit 60. In addition, when the count value of the credit counter reaches the upper limit, or when the count value reaches the upper limit during the addition of the payout number, the medal payout rotating plate is driven and the medal is discharged from the hopper device 51. It pays out to the medal tray 50 through the exit 49. In the medal payout process, a process of changing the payout number displayed on the payout number display unit 62 in accordance with the medal payout is also performed. If the current gaming state is the BB state, the payout number is subtracted from the value of a later payout number counter, which will be described later, and the remaining payout number displayed on the remaining payout number display unit 61 is subtracted. .

  Next, the RT state process of step S211 will be described based on the flowchart of FIG.

  In step S601, it is determined whether or not the current gaming state is an RT preparation state. If it is in the RT ready state, the process in the ready state shown in steps S602 to S607 is executed, and the RT state process is terminated. If it is not in the RT ready state, the process proceeds to step S608, and it is determined whether or not the current gaming state is in the RT state. When it is in the RT state, the RT end determination process shown in steps S609 to S613 is executed, and the RT state process is ended. If it is not in the RT state, the RT state process is terminated without executing the above processes.

  The details of the preparatory state process and the RT end determination process will be described later in order to facilitate understanding of the game characteristics of the slot machine 10.

  Next, the BB state process of step S212 will be described based on the flowchart of FIG.

  Prior to the description of the BB state process, the BB state will be described. The BB state is composed of a plurality of RB states. The RB state consists of 12 JAC games. A JAC game is a game in which the probability that a prize (for example, a bell prize or the like) to which a medal payout privilege is granted is established is higher than that in a normal state. If the winning is established 8 times during the JAC game, the RB state is ended even before the JAC game is played 12 times. Further, the BB state ends when the number of medals paid out reaches a predetermined number (specifically, 400). In addition, when the medal payout number reaches a predetermined number in the middle of the RB state, not only the BB state but also the RB state ends. This is a contrivance for suppressing the player's euphoria by giving an upper limit to the number of medals paid out during the BB state, and ensuring the soundness of the game. Further, in the present embodiment, the combination of symbols that shift to the RB state is not set, and the configuration shifts to the RB state immediately after the transition to the BB state and immediately after the RB state ends. Therefore, it can be said that the BB state is a game that continuously shifts to the RB state until a predetermined number of medals are paid out. In the present embodiment, the number of medals owned by the player is increased by 217 between the transition to the BB state and the end.

  In the BB state process, first, in step S701, it is determined whether or not the current gaming state is the BB state. If not in the BB state, BB determination processing shown in steps S702 to S705 is performed.

  In the BB determination process, it is determined in step S702 whether the BB winning flag is set. If the BB winning flag is set, the process proceeds to step S703, and it is determined whether or not a BB winning has been established based on the winning combination set in the previous payout determination process. When a BB winning is established, a BB start process is executed in step S704 to shift the gaming state to the BB state. Specifically, the BB winning flag is cleared and the BB setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the BB state. Further, a process of setting 400 in the remaining payout counter for counting the remaining number of medals that can be paid out during the BB state provided in the state information storage area 106c and displaying 400 on the remaining payout number display unit 61. I do. Thereafter, an RB start process is performed in step S705, and the BB state process is terminated. In the RB start process, the RB setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the RB state. In addition, 8 is set in the remaining payout payout counter for counting the number of winnings established in the RB state, and 12 is set in the remaining JAC game counter for counting the number of remaining JAC games. The remaining payout / winning counter and the remaining JAC winning counter are provided in the state information storage area 106c. The determination of the current gaming state in step S701 or the like is executed based on whether or not the setting flag corresponding to the state information storage area 106c is set, and when no setting flag is set. Determines that the current gaming state is the normal state.

  On the other hand, when the BB winning flag is not set (when step S702 is NO) or when the BB winning is not established (when step S703 is NO), the BB start process or the like is not executed. The process ends.

  If it is determined in step S701 that the current gaming state is the BB state, the process proceeds to step S706, and it is determined whether or not a winning has been established based on the winning winning combination set in the previous payout determining process. . If a winning is achieved, 1 is subtracted from the value of the remaining payout winning counter in step S707. Thereafter, or when it is determined in step S706 that no winning has been established, one JAC game has been consumed, and thus the value of the remaining JAC game counter is decremented by 1 in step S708. Subsequently, in step S709, it is determined whether either the remaining payout / winning counter or the remaining JAC game counter has become zero. If any of them is 0, that is, if the winning is established 8 times or the JAC game is consumed 12 times, it means that the RB state termination condition is established, so in step S710, the remaining payout winning / winning counter And the RB end processing for clearing the value of the remaining JAC game counter is performed. In subsequent step S711, it is confirmed whether or not the count value of the remaining payout counter is zero. If it is not 0, it means that the number of medals paid out during the BB state has not reached the predetermined number and the end condition for the BB state is not satisfied, so that the process proceeds to step S712 and the RB start described above is started. After performing the processing, the present processing is terminated.

  In step S709, when neither the remaining payout / payout counter or the remaining JAC game counter is 0, that is, when the winning has not been established 8 times and the JAC game has not been consumed 12 times, step S713 is performed. Then, it is confirmed whether or not the count value of the remaining payout counter is 0. If it is not 0, it means that the number of medals paid out during the BB state has not reached the predetermined number and the end condition for the BB state is not satisfied. On the other hand, when the count value of the remaining payout counter is 0, it means that the BB state end condition is satisfied, and therefore, the special game state end process shown in steps S714 to S715 is performed. In the special game state end process, first, in step S714, the RB end process described above is performed. After that, in step S715, a BB end process for appropriately clearing the BB setting flag and various counters and performing an ending process is performed. In addition, when the count value of the remaining payout number counter is 0 in step S711, it means that the BB state end condition is satisfied, and therefore the BB end process is performed in step S715. After performing the BB termination process, the state transition process is executed in step S716, and the BB state process is terminated. Here, the state transition process is a process for shifting the gaming state to the RT preparation state, and specifically, a process of setting the RT preparation setting flag in the state information storage area 106c of the RAM 106 is executed.

  As described above, in this embodiment, when the BB state ends, the state transition process is executed in step S716, and the gaming state shifts to the RT preparation state. Therefore, hereinafter, processing executed in the RT preparation state will be described.

  First, an outline of the RT preparation state will be described. The RT preparation state is a gaming state in which there is a possibility that a second regame prize and a third regame prize will be established. Then, the RT preparation state ends when either the second re-game winning or the third re-game winning is achieved or when BB is won.

  In the lottery process in the RT preparation state (see FIG. 12), the lottery table for the RT preparation state is selected in step S302, and the winning / failing determination of the combination is executed using the lottery table.

  As shown in FIG. 19A, the first lottery table selected under the RT preparation state includes the same bell, watermelon, cherry, and the like as the normal state lottery table (see FIG. 13). While the five combinations of the single combination and BB are set, the first replay is not set. That is, in the RT preparation state, whether or not the first regame is successful is not performed. Then, as a role to be determined instead of the first regame, a second regame and a third regame are set. The same point value PV as in the normal state lottery table is set for each of the five combinations of bell, watermelon, cherry, one-sheet combination, and BB. Regarding the second regame and the third regame point value PV, the point value PV of the first regame in the normal state lottery table is 8976, but is set to 4488 and a half value respectively. Therefore, in the RT ready state, the above five roles are won with the same probability as in the normal state, the second replay is won with a probability of about 14.6, and the probability is about 14.6. Wins the third replay and loses with a probability of about 1.36. The probability of winning the second or third replay is about 7.30. In other words, when the gaming state shifts to the RT ready state, whether or not the second regame and the third regame are determined instead of the first regame is determined, and the second regame prize or the third regame prize is determined. An opportunity will be established.

  In the lottery process, when the determination is affirmative in step S305 when IV = 1, in step S306, the second re-game winning flag is set in the winning flag storage area 106a of the RAM 106. In the subsequent step S309, a lottery result command indicating that the second regame has been won is set. When the display control device 81 receives the lottery result command indicating that the second regame has been won, the upper control unit 63 and the auxiliary display unit indicate that the second regame winning can be established. 65 drive control is executed. Similarly, if affirmative determination is made in step S305 when IV = 2, in step S306, the third re-game winning flag is set in the winning flag storage area 106a of the RAM 106, and in step S309, the third re-game is set. A lottery result command indicating that the player has won is set. When the display control device 81 receives a lottery result command indicating that the third regame has been won, the upper control unit 63 and the auxiliary display unit indicate that it is possible to establish the third regame prize. 65 drive control is executed. That is, in the case of winning the second replay or the third replay, it is suggested which role is won by the upper lamp 63 or the auxiliary display unit 65. Note that the above-described second re-game winning flag and third re-game winning flag are reset after the game is over (see S203 of the normal process). In the slip table setting process of step S310, when the second replay is won, the slip table shown in FIG. 14 is set. In other words, the sliding table shown in FIG. 14 is a sliding table that is set first when the second regame is won.

  In the slip table, the “replay” symbol which is the second replay symbol of the left reel 42L is set to stop at either the upper stage or the lower stage. The middle reel 32M is set so that the “replay” symbol as the second replay symbol stops at the middle stage. For example, if the middle stop switch 43 is operated while the No. 13 “Bell” symbol has reached the lower level, the middle reel 32M stops without slipping, and the No. 14 “Replay” symbol stops at the middle level. To do. Further, when the middle stop switch 43 is operated while the 14th “replay” symbol has reached the lower stage, the middle reel 32M slides by 3 patterns, and the 17th “bell” symbol stops at the lower stage. At the same time, the 18th “replay” symbol stops in the middle. The right reel 32R is set so that the “red 7” symbol, which is the second replay symbol, stops in the middle. For example, if the right stop switch 44 is operated while the 18th “white 7” symbol has reached the lower level, the right reel 32R slides by 4 symbols, and the 1st “bell” symbol stops at the lower level. At the same time, the second “Red 7” symbol stops in the middle.

  Here, the symbol arrangement of the right reel 32R will be described.

  On the right reel 32R, the “red 7” symbol which is the second re-game symbol is arranged at the second, fourth and seventh positions. The 2nd “Red 7” design and the 4th “Red 7” design are separated by 1 design on the rotating side of the right reel 32R, and the 4th “Red 7” design and the 7th “Red 7” design. Is separated into two symbols on the rotating side of the right reel 32R. Further, the right reel 32R can be stopped after sliding a maximum of four symbols. For this reason, when the right stop switch 44 is operated while the 19th “watermelon” symbol to the 7th “red 7” symbol has reached a predetermined position such as the lower stage, the “red” is displayed at the predetermined position. 7 "The symbol can be stopped. On the other hand, the “red 7” symbol of No. 7 and the “red 7” symbol of No. 2 are separated by 15 symbols on the rotating side of the right reel 32R. For this reason, when the right stop switch 44 is operated while the “Watermelon” symbol from No. 8 to the “White 7” symbol from No. 18 reaches the predetermined position, “Red 7” is displayed at the predetermined position. The symbol cannot be stopped. In the present embodiment, three symbols of the upper, middle and lower stages are visible from the display window 26R, and an effective line is set at each of these positions. Therefore, when the right stop switch 44 is operated when the “Bell” symbol from No. 17 to the “Red 7” symbol from No. 7 has reached the lower level, it is placed at any of the upper level, middle level, and lower level. The “Red 7” symbol can be stopped. For example, when the right stop switch 44 is operated when the “Bell” symbol of No. 17 has reached the lower stage, if the right reel 32R is slid by four symbols and then stopped, it becomes the second replay symbol. The “Red 7” symbol can be stopped at the top. In addition, when the right stop switch 44 is operated when the 18th “white 7” symbol has reached the lower stage, the second re-playing symbol can be obtained by sliding the right reel 32R after sliding four symbols. The red “7” symbol can be stopped in the middle, and if the right reel 32R is stopped after sliding three symbols, the “red 7” symbol as the second replay symbol can be stopped in the upper stage. .

  Further, on the right reel 32R, the “white 7” symbol which is the third re-game symbol is arranged at the 12th, 15th and 18th positions. The 12th "White 7" design and the 15th "White 7" design are separated by 2 designs on the rotating side of the right reel 32R. The 15th "White 7" design and the 18th "White 7" design Is separated into two symbols on the rotating side of the right reel 32R. For this reason, when the right stop switch 44 is operated when the 8th “watermelon” symbol to the 18th “white 7” symbol has reached a predetermined position such as the lower stage, the “white” is displayed at the predetermined position. 7 "The symbol can be stopped. On the other hand, the 18th “white 7” symbol and the 12th “white 7” symbol are separated by 14 symbols on the rotating side of the right reel 32R. For this reason, when the right stop switch 44 is operated while the 19th “watermelon” symbol to the 7th “red 7” symbol has reached the predetermined position, the “white 7” is displayed at the predetermined position. The symbol cannot be stopped. In the present embodiment, three symbols of the upper, middle and lower stages are visible from the display window 26R, and an effective line is set at each of these positions. Therefore, when the right stop switch 44 is operated when the “Bell” symbol from No. 6 to the “White 7” symbol from No. 18 has reached the lower level, it is placed at any of the upper, middle, and lower levels. The “white 7” symbol can be stopped. For example, when the right stop switch 44 is operated while the 6th “bell” symbol has reached the lower stage, if the right reel 32R is slid by 4 symbols and then stopped, it becomes the third replay symbol. The “white 7” symbol can be stopped in the upper stage. In addition, when the right stop switch 44 is operated when the No. 7 “Red 7” symbol has reached the lower stage, if the right reel 32R is slid by four symbols and then stopped, the third replay symbol The “white 7” symbol can be stopped in the middle stage, and if the right reel 32R is stopped after sliding three symbols, the “white 7” symbol as the third replay symbol can be stopped in the upper stage. .

  In this way, when the right stop switch 44 is operated when the 19th “watermelon” symbol to the 7th “red 7” symbol have reached the predetermined position, the “white 7” is displayed at the predetermined position. Although the symbol cannot be stopped, the “red 7” symbol can be stopped. In addition, when the right stop switch 44 is operated when the “Watermelon” symbol from No. 8 to the “White 7” symbol from No. 18 reaches the predetermined position, the “Red 7” symbol is displayed at the predetermined position. Although it cannot be stopped, the “white 7” symbol can be stopped. That is, the right reel 32R can stop the “red 7” symbol at a predetermined position (the 19th to the seventh zone) and the “white 7” symbol at a predetermined position. A “red 7” symbol and a “white 7” symbol are arranged so that a section (a section from No. 8 to No. 18) is formed. Therefore, when winning the second replay or the third replay, it is necessary to operate the right stop switch 44 at a timing at which the corresponding winning symbol can be reached on the effective line where the winning is established, If the right stop switch 44 is not operated at the above timing, a missing item will occur.

  For example, when the “replay” symbols of the left reel 32L and the middle reel 32M are stopped side by side on the lower right line L4 in the situation where the second replay is won, the symbols No. 19 to No. 7 are in the lower row. If the right stop switch 44 is operated while reaching, the second re-game winning can be established, and the right stop switch 44 can be operated when the 8th to 18th symbols reach the lower stage. In this case, the second replay winning prize is not established, and the game is lost. When the right stop switch 44 is operated to stop the right reel 32R first, the “red 7” symbol of the right reel 32R is stopped at any of the upper, middle, and lower positions. There is a possibility that a second replay winning prize will be established. Therefore, when the right stop switch 44 is operated for the first time, if the right stop switch 44 is operated when the symbols 17 to 7 have reached the lower stage, there is a possibility that the second regame winning will be established. If the right stop switch 44 is operated while the symbols No. 8 to No. 16 have reached the lower stage, the second re-game winning will not be established and a loss will occur. Further, as described above, the “replay” symbol is arranged on each reel 32L, 32M, 32R so that it can be stopped at any position regardless of the operation timing of the stop switches 42-44. Therefore, in a situation where the second regame is won, the second regame winning is established or the missed out occurs depending on the operation timing of the right stop switch 44. The same applies to the case where the third regame is won.

  In the RT state process under the RT preparation state (see FIG. 17), an affirmative determination is made in step S601, and the processing in the preparation state in steps S602 to S607 is executed. In step S602, based on the winning combination set in the payout determination process, it is determined whether or not the second re-game winning is achieved. If the second re-game winning is established, a first RT start process is executed to shift the gaming state to the first RT state in step S603, and the RT state process is terminated. In the first RT start process, the RT preparation setting flag stored in the state information storage area 106c of the RAM 106 is cleared and the first RT setting flag is set in the state information storage area 106c to set the gaming state to the first RT state. . In addition, 72 is set in a remaining game number counter for counting the number of remaining games in the RT state provided in the state information storage area 106c.

  Here, the first RT state will be briefly described. The first RT state is a gaming state in which the first RT state lottery table set for the first RT state is selected in the lottery process described above, and whether or not each winning combination is determined based on the lottery table. The first RT state ends when a predetermined number of games (72 times in the present embodiment) are played or BB is won.

  FIG. 19B is a first RT state lottery table selected under the first RT state of “setting 3”. In the first RT state lottery table, the same combination as that in the normal state lottery table is set as a combination to be judged. Further, the point value PV of the bell, watermelon, cherry, one-piece combination, and BB is set to the same value as the normal state lottery table, but the point value PV of the first replay is set in the normal state lottery table. While the value is 8976, 55968 is set very high. Therefore, when the state transitions to the first RT state, the probability of winning the first replay becomes very high. Since the first regame prize is a prize that is established regardless of the operation timing of the stop switches 42 to 44, the probability that the first regame prize is established is very high. By the way, when the lottery table shown in FIG. 19B is selected, the winning combination other than the first replay is won with the same probability as in the normal state, and the first replay is about 1.17 times smaller. Wins with a probability, and does not win any role with a probability of about 1 in 50.8. That is, the first RT state is a gaming state in which the percentage of games in which no winning is achieved is lower than in the normal state, and the first re-game winning is established with high probability. Therefore, when shifting to the first RT state, the player can play the game a predetermined number of times in a state that is more advantageous than the normal state.

  If it is determined in step S602 that the second re-game winning is not established, the process proceeds to step S604, and whether or not the third re-game winning is established based on the winning combination set in the payout determination process. Determine whether. If the third re-game winning is established, a second RT start process is executed in step S605 to shift the gaming state to the second RT state, and the RT state process is terminated. In the second RT start process, the RT preparation setting flag stored in the state information storage area 106c of the RAM 106 is cleared, and the second RT setting flag is set in the state information storage area 106c to set the gaming state to the second RT state. . Further, 175 is set in the remaining game number counter for counting the number of remaining games in the RT state provided in the state information storage area 106c.

  Here, the second RT state will be briefly described. The second RT state is a gaming state in which the lottery table for the second RT state set for the second RT state is selected in the lottery process described above, and whether or not each winning combination is determined based on the lottery table. Then, similarly to the first RT state, the second RT state ends when a predetermined number of games (175 times in the present embodiment) are played or BB is won.

  FIG. 19C is a lottery table for the second RT state selected under the second RT state of “setting 3”. In the second RT state lottery table, the same combination as that in the normal state lottery table is set as a combination to be determined. Further, the point value PV of the bell, watermelon, cherry, one-piece combination, and BB is set to the same value as the normal state lottery table, but the point value PV of the first replay is set in the normal state lottery table. While the value is 8976, it is set to 33260 which is very high. Therefore, when the state transitions to the second RT state, the probability of winning the first replay becomes very high. Since the first regame prize is a prize that is established regardless of the operation timing of the stop switches 42 to 44, the probability that the first regame prize is established is very high. By the way, when the lottery table shown in FIG. 19 (c) is selected, a combination other than the first replay is won with the same probability as in the normal state, and the first replay is about 1.97 times. Wins with a probability, and does not win any role with a probability of about 1 / 2.73. That is, the second RT state is a gaming state in which the percentage of games in which no winning is achieved is lower than in the normal state, and the first re-game winning is established with high probability. Therefore, when shifting to the second RT state, the player can play the game a predetermined number of times in a state that is more advantageous than the normal state. In addition, when compared with the first RT state, when the state transitions to the second RT state, the proportion of games in which the first re-game winning is achieved is low and the proportion of games in which none of the winnings is achieved is high, while the state is more advantageous than the normal state. More games can be played than in the first RT state.

  If neither the second re-game winning or the third re-game winning is achieved in the RT preparation state, the process proceeds to step S606, and it is determined whether or not the BB winning flag is set in the winning flag storage area 106a. To do. If the BB winning flag is set, the process proceeds to step S607, the RT preparation setting flag stored in the status information storage area 106c of the RAM 106 is cleared, and this process ends. As a result, when the BB is won in the RT preparation state, the gaming state shifts from the RT preparation state to the normal state. On the other hand, if the BB winning flag is not set, the process is terminated as it is.

  As described above, when the second re-game prize or the third re-game prize is established under the RT preparation state, the gaming state shifts from the RT preparation state to the first RT state or the second RT state. Under these RT states, an affirmative determination is made in step S608 of the RT state process, and an RT end determination process shown in steps S609 to S613 is executed.

  In the end determination process, first, 1 is subtracted from the value of the remaining game number counter in step S609, and it is determined whether or not the value of the remaining game number counter is 0 in step S610. If the value of the remaining game number counter is 0, it means that a predetermined number of games have been played in the first RT state or the second RT state, and therefore, stored in the state information storage area 106c of the RAM 106 in step S611. This RT setting flag is cleared, and this process is terminated. As a result, when the game is played a predetermined number of times under the RT state, the gaming state shifts from the first RT state or the second RT state to the normal state. If the value of the remaining game number counter is not 0, the process advances to step S612 to determine whether or not the BB winning flag is set in the winning flag storage area 106a. If the BB winning flag is set, the process proceeds to step S613, and the value of the remaining game number counter is cleared. Thereafter, in step S611, the RT setting flag stored in the state information storage area 106c of the RAM 106 is cleared, and this process ends. As a result, when the BB is won in the RT state, the gaming state shifts from the first RT state or the second RT state to the normal state. On the other hand, if the value of the remaining game number counter is not 0 and the BB winning flag is not set (when both step S610 and step S612 are NO), it means that the termination condition for the RT state is not satisfied. Therefore, this process is finished as it is.

  Next, the player's advantageous degree in the normal state, the first RT state, and the second RT state, more specifically, the expected value of the medal payout in each gaming state, and the medal possessed by the player after the end of the BB state The transition will be described. In the following, description will be made on the premise that a corresponding winning is established in the game won in the lottery. In addition, when the BB is won, the number of medals owned by the player in the BB state increases by 217, so when the BB winning is established, 220 bets (that is, the number of medals increased to 217 is the BB winning game bet). It is assumed that the medal payout of the value obtained by adding Equation 3 is performed. Similarly, when the first regame is won, it is possible to play the next game without inserting medals, and therefore, when the first replay prize is established, three medals are paid out. Assumed to be done.

  The winning probability of each combination in the normal state is about 1/200 of the BB winning probability, about 1/30 of the first replay winning probability, about 10.9 of the bell winning probability, watermelon winning probability Is 1/128, the cherry winning probability is approximately 73.0 / 1, and the single-piece winning probability is 1/128. The number of medals to be paid out when winning the prize is 220 for BB, 3 for the first replay, 8 for the bell, 6 for the watermelon, 4 for the cherry, and 1 for the winning combination. Here, the 220 medals to be paid out at the time of winning the BB are actually paid out under the BB state, and therefore need not be considered under the normal state. Therefore, the expected value of the medal payout per game under the normal state is equal to the value obtained by multiplying the medal payout number corresponding to the winning probability of each combination other than BB, and adding these multiplication results, which is about 1.25. It becomes a sheet. Since three medals are required to play one game, when a game is played in a normal state, the player's medal is reduced by about 1.75 for each game. There is expected.

  The winning probability of each combination in the first RT state is the same as the winning probability in the normal state, except that the first replay winning probability is about 1.17. Also, 220 medals paid out at the time of winning the BB need not be considered in the first RT state as in the normal state. Therefore, the expected value of medal payout per game under the first RT state is equal to a value obtained by multiplying the number of medal payouts corresponding to the winning probability of each combination other than BB, and adding the multiplication results. It will be 41 sheets. In other words, when a game is played in the first RT state, it is expected that medals owned by the player increase by about 0.41 for every game played.

  The winning probability of each combination in the second RT state is the same as the winning probability in the normal state, except that the first replay winning probability is about 1.97. Further, 220 medals paid out at the time of winning the BB need not be considered in the second RT state as in the normal state. Therefore, the expected value of medal payout per game under the second RT state is equal to the value obtained by multiplying the number of medal payouts corresponding to the winning probabilities of each combination other than BB and adding these multiplication results. 37 sheets. In other words, when a game is played in the second RT state, it is expected that the medals owned by the player will decrease by about 0.63 each time one game is played.

  FIG. 20 is a diagram illustrating the transition of the expected value of owned medals when the game is continuously performed after the BB state ends. The solid line in the figure shows the transition of the expected value of owned medals when the RT preparation state shifts to the normal state via the first RT state, and the broken line passes from the RT preparation state to the second RT state. This shows the transition of the expected value of the owned medal when the state is shifted to the normal state.

  When the BB state ends, the player's owned medals increase by 217 compared to before the transition to the BB state. Thereafter, when the second re-game winning is established in the first game after the end of the BB state, the gaming state shifts to the first RT state without increasing or decreasing the number of owned medals. In the first RT state, it is expected that the number of owned medals will increase by about 0.41 every time one game is played. It is expected that the number of owned medals will increase by about 247 compared to before the transition to the BB state. After that, since the gaming state shifts from the first RT state to the normal state, it is expected to decrease by about 1.75 each time one game is played until a BB winning is established.

  On the other hand, when the third re-game winning is established in the first game after the end of the BB state, the gaming state shifts to the second RT state without increasing or decreasing the number of owned medals. In the 2nd RT state, it is expected that the number of owned medals will decrease by about 0.63 every time one game is played. It is expected that the number of owned medals will increase by about 106 compared to before the shift to the BB state. After that, since the gaming state shifts from the first RT state to the normal state, it is expected to decrease by about 1.75 each time one game is played until a BB winning is established.

  As described above, when the state is shifted to the first RT state after the end of the BB state, the number of owned medals is expected to increase while 72 games are played in the first RT state, and thereafter the game in the normal state As a result, it is expected that the number of owned medals will decrease sharply. On the other hand, when transitioning to the 2nd RT state after the end of the BB state, the number of owned medals cannot be expected to increase as in games in the 1st RT state, but the number of owned medals will decrease for a relatively long period of 175 games. It can be expected to suppress. Then, when 140 games are played after the BB state is finished, more specifically, when the 139 games are played after the transition to the first RT state or the second RT state, the state is changed to the first RT state. The expected value of the increase of owned medals in the case of shifting is almost equal to the expected value of the increase of owned medals in the case of shifting to the second RT state. More precisely, at the stage of the 139th game, the expected value of the increase in possession medals when shifting to the first RT state is about 0.96 more, and at the stage of the 140th game, the transition to the second RT state is made. In this case, the expected value of increase of owned medals is about 0.16 more. When transitioning to the 2nd RT state, it is possible to play 36 games thereafter in the 2nd RT state. Therefore, when transitioning to the 1st RT state or the 2nd RT state, playing 140 games or more. In the case of shifting to the second RT state, the expected value for the increase in possession medals is higher than in the case of shifting to the first RT state. Conversely, if only less than 139 games are played after the transition to the first RT state or the second RT state, the medal possessed in the transition to the first RT state is more than the transition to the second RT state. The expected value of the increase of

  The degree of expectation for winning the BB will be described.

  The expectation of winning the BB in the first game immediately after the end of the BB state is about 1/200, that is, about 0.500% because the BB winning probability is about 1/200. The expectation of winning the BB in the second game after the BB state ends is the probability that the BB will not be won in the first game (approximately 199/200) and the probability that the BB will be won in the second game (approximately 200 minutes) Of 1) and about 1/201, that is, about 0.498%. Similarly, the expectation level of winning the BB in the third game after the end of the BB state is the probability of not winning the BB in the first game (approximately 199/200) and the probability of not winning the BB in the second game ( Since it is a value obtained by multiplying the probability of winning the BB in the third game (approximately 1/200), it is approximately 1/202, that is, approximately 0.495%. Thus, the probability of winning the BB in the nth game after the end of the BB state is the probability that all the BBs will not be won until the (n-1) th game after the BB state ends, and the BB winning in the nth game. Is a value obtained by multiplying the probability by The expectation level for winning the BB by the nth game after the end of the BB state is the cumulative addition of the expectation levels from the first game to the nth game after the end of the BB state. FIG. 21 shows the relationship between the number of games played after the end of the BB state and the expected degree of BB winning between the end of the BB state and the number of games. As shown in FIG. 21, in the present embodiment, in the 139th game after the end of the BB state, the expected degree of winning the BB so far is about 50%. In other words, if a game of 139 games or more is performed after the BB state ends, it can be expected that BB is won again with a probability of 50% or more.

  Next, with regard to the exit rate when the game is played by always shifting to the first RT state after the end of the BB state, and the exit rate when the game is performed by always shifting to the second RT state after the end of the BB state. Think. The payout rate is an expected value of the ratio of medal payout with respect to the number of medal inserted. Note that the BB state and the RT preparation state are not taken into consideration because the game rate is the same regardless of which game is played. In order to facilitate understanding, the description will be made assuming that the state transitions to the first RT state or the second RT state without passing through the RT preparation state after the end of the BB state.

  The winning probabilities for each role other than the first replay are BB winning probability is about 1/200, Bell winning probability is about 10.9 / 1, watermelon winning probability is 1/128, regardless of the gaming state. The cherry winning probability is approximately 1 / 733.0 and the winning combination probability is 1/128. The number of medals to be paid out at the time of winning is 220 for BB, 8 for bell, 6 for watermelon, 4 for cherry, and 1 for winning. Therefore, the expected value of medal payout per game for each of these combinations is equal to the value obtained by multiplying the number of medal payouts corresponding to the winning probability of each of these combinations and adding the multiplication results, and is about 1.94. Become.

  As for the first replay, since the winning probabilities differ depending on whether the gaming state is the normal state or the RT state, it is necessary to consider the proportion of the number of games under the RT state out of the total number of games. is there.

  When one unspecified game is selected, the probability that the game is the first game after the end of the BB state is about 1/200 because the BB winning probability is about 1/200, that is, about 0.500%. It is. The probability that the selected game is the second game after the end of the BB state is the probability that the game before the selected game is the first game after the end of the BB state (about 1/200) and the probability that the selected game is the BB Since it is a value obtained by multiplying the probability of not being the first game after the end of the state (approximately 199/200), it is approximately 1/201, that is, approximately 0.498%. Similarly, the probability that the selected game is the third game after the end of the BB state is selected as the probability (about 1/200) that the two games before the selected game are the first game after the end of the BB state. Multiply the probability that the previous game is not the first game after the end of the BB state (approximately 199/200) and the probability that the selected game is not the first game after the end of the BB state (approximately 199/200) Therefore, it is about 1/202, that is, about 0.495%. Thus, the probability that the selected game is the nth game after the end of the BB state is the (n-1) probability that the game before the selected game is the first game after the end of the BB state, and (n-2) ) A value obtained by multiplying all the games from before the game to the selected game by the probability that it is not the first game after the end of the BB state. The probability that the selected game is one of the first game after the end of the BB state to the nth game is cumulatively added from the probability of the first game after the end of the BB state to the probability of the nth game. It will be a thing. Therefore, the probability that the selected game is one of the first game to the 72nd game after the end of the BB, that is, the proportion of the total number of games in the first RT state is about 30.3%. . Similarly, the probability that the selected game is one from the first game to the 175th game after the end of the BB, that is, the proportion of the total number of games in the second RT state is about 58.4%. Become.

  When a game is played by always shifting to the first RT state after the end of the BB state, the first replay winning probability under the normal state is about 7.30, and the first regame winning under the first RT state is The probability is about 1/17, and the number of medals to be paid out when winning is established is three. The ratio of the number of games under the first RT state to the total number of games is about 30.3%, and the ratio of the number of games under the normal state is about 69.7%. Therefore, the expected value of medal payout per game related to the first replay includes the first replay win probability, the medal payout number 3 and the proportion of the number of games under the corresponding gaming state in the normal state and Multiplying for the first RT state, the result is equal to the added value, which is about 1.06. Therefore, when a game is performed by always shifting to the first RT state after the end of the BB state, the expected value of medal payout per game under the game state other than the BB state and the RT ready state is about 3.00. It becomes a sheet. Since three medals are required to play one game, the rate of play when a game is played by always shifting to the first RT state after the end of the BB state is about 100%. More precisely, the expected value of medal payout per game under the gaming state other than the BB state and the RT ready state is about 3.0058, and after the BB state ends, the game is always performed by shifting to the first RT state. In this case, the output rate is about 100.19%.

  If the game is played after the BB state has always been shifted to the second RT state, the first regame winning probability under the normal state is about 7.30th, and the first regame winning under the second RT state The probability is about 1/97, and the number of medals to be paid out at the time of winning is three. The ratio of the number of games under the second RT state to the total number of games is about 58.4%, and the ratio of the number of games under the normal state is about 41.6%. Therefore, the expected value of the medal payout per game related to the first replay is the first replay win probability, the medal payout number 3 and the ratio of the number of games under the corresponding game state. It is equal to the value obtained by multiplying the 2RT state and adding the result, which is about 1.06. Therefore, when a game is performed by always shifting to the second RT state after the end of the BB state, the expected value of medal payout per game under the game state other than the BB state and the RT ready state is about 3.00. It becomes a sheet. Since three medals are required to play one game, the rate of play when the game is played by always shifting to the second RT state after the end of the BB state is about 100%. More precisely, the expected value of paying out medals per game under the gaming state other than the BB state and the RT ready state is about 3.0032, and the game is always performed after the BB state is finished and the state is shifted to the first RT state. In this case, the output rate is about 100.10%.

  As described above, in the present embodiment, even if the transition is made to any RT state after the end of the BB state, there is almost no difference in the exit rate. For example, if the game is played 215 times after the BB state has been completed and the game has been played 215 times, the expected value of medals to be paid out during the 215 games is about 646.25, and the player bets The number of medals to be played is 645, and the difference is about 1.25. Similarly, if 215 games are played after the BB state has been completed and the game has been played 215 times, the expected medal value to be paid out during the 215 games is about 645.69, The number of medals to bet is 645 and the difference is about 0.69. Therefore, the difference number when the game is played 215 times after the transition to the first RT state after the end of the BB state, and the difference number when the game is performed 215 times after the transition to the second RT state after the completion of the BB state. And the difference is 0.56 sheets, which is 1 sheet or less. Here, 215 times means the reciprocal of the BB winning probability (about 1/200) that becomes a trigger for the transition to the RT ready state, and the winning probability (about 14 for the second replay and the third replay in the RT ready state). The sum of the reciprocal of 1/6) is converted to an integer, in other words, the reciprocal of the transition probability to the corresponding RT state. By the way, even if the number of differences in 214 games is compared, the difference is 0.56, which is 1 or less.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  When the state transitions to the RT preparation state, whether or not the second regame and the third regame are successful is determined instead of the first regame. If the right stop switch 44 is operated at a timing at which the “red 7” symbol can be reached on the active line where the winning is established in the situation where the second replay is won, A re-game winning is established and the gaming state shifts to the first RT state. On the other hand, if the right stop switch 44 is operated at a timing at which it is impossible to reach the “red 7” symbol on the active line where the winning is established, the second re-game winning is not established and the RT ready state is established. Will continue. Similarly, in the situation where the third replay is won, when the right stop switch 44 is operated at a timing at which the “white 7” symbol can be reached on the active line where the winning is established, Three re-game winnings are established and the gaming state shifts to the second RT state. On the other hand, if the right stop switch 44 is operated at a timing when it is impossible to reach the “white 7” symbol on the active line where the winning is established, the third re-game winning is not established and the RT ready state is established. Will continue. With this configuration, in the RT preparation state, the player is allowed to select whether to shift to the first RT state or the second RT state through whether or not the right stop switch 44 is operated in order to establish a prize. It becomes possible. Therefore, it is possible to make the player actively participate in the game and to suppress the dilution of the impression of actively participating in the game among the repeated games. Furthermore, by making the player select which RT state to shift to through the operation of the stop switch, the selection can be executed without hindering the progress of the game. For example, when the slot machine is configured to have a selection switch for selecting which RT state to shift to, the operation of the selection switch is performed separately from the act of operating the stop switch to stop the rotating reel. This is because it may be necessary for the player to feel annoyed or forget to operate the selection switch.

  When the first RT state is entered, 72 games are executed or when the BB is won, the first RT state is terminated, and when the second RT state is entered, 175 games are executed. The configuration is such that the second RT state is terminated when Ruka BB is won. Thus, by providing a difference in the number of games that can be executed under the RT state, it becomes possible for the player to select which RT state to shift to according to the situation at that time. In other words, if only 72 games or less can be executed after the transition to the RT state, the establishment of the third re-game winning is avoided in the situation where the third re-game is won, and the second re-game is won. In this situation, the right stop switch 44 may be operated in order to establish the second re-game win, and if the game of 175 games or more can be executed after shifting to the RT state, the second re-game is won. This is because it is only necessary to operate the right stop switch 44 in order to avoid the establishment of the second re-game prize in the situation where the third re-game prize is won and to establish the third re-game prize in the situation where the third re-game prize is won. Therefore, it is possible to entertain the player in the RT state regardless of the length of the game time that the player can play.

  When comparing the degree of advantage per game, the game in the first RT state has a greater degree of advantage than the game in the second RT state. By adopting such a configuration, it is possible to more strongly promote selection of whether to shift to the first RT state or the second RT state. When the first RT state and the second RT state are compared, the first RT state has a large degree of advantage per game, but the RT state ends early, and the second RT state has a small degree of advantage per game but is long-term. This is because the RT state continues for a long time.

  In the game under the first RT state, an increase of about 0.41 medals is expected every time one game is played, and in the game under the second RT state, about 0.63 each time a game is played. The medal is expected to decrease. By adopting such a configuration, a clear difference can be provided between the first RT state and the second RT state, and it is possible to more strongly encourage selection of whether to shift to the first RT state or the second RT state. Become. A player who can execute only 72 games or less after shifting to the RT state may shift to the first RT state where an increase in owned medals can be expected without winning BB if the game is played. This is because a player who can execute the RT and who wants to enjoy the RT state for as long as possible should shift to the second RT state.

  In addition, when a game with 175 games, that is, a game that ends the second RT state is performed after the transition to the first RT state, the medal possessed is more than when a game of 175 games is performed after the transition to the second RT state. The increase is expected to be low. By adopting such a configuration, it is possible to give a player a game under the RT state regardless of the length of the playable game time while clarifying the intention of the player to select one of the first RT state and the second RT state. Can be entertained. A player who can only execute a game of 72 games or less after shifting to any one of the RT states may shift to the first RT state in which an increase in owned medals can be expected without winning BB if the game is played. This is because the player who can execute the game of the game may shift to the second RT state in which the expectation of the BB winning can be expected while suppressing the decrease of the owned medals.

  In addition, in the game of the 139th game in which the expected value of the increase of owned medals in the case of shifting to the first RT state is substantially equal to the expected value of the increase of owned medals in the case of shifting to the second RT state. The BB winning probability was set so that the expectation level for winning the BB was about 50%. In such a configuration, a player who can execute a game of 175 games or more may shift to the first RT state if he / she is confident of winning BB within the following 139 games in a situation where a plurality of winning combinations are won. . This is because when BB is actually won, more medals can be owned as compared with the case where the state is shifted to the second RT state. On the other hand, a player who is not confident of winning the BB within 139 games may shift to the second RT state instead of the first RT state. This is because, when the BB is not actually won, more medals can be owned as compared with the case of shifting to the first RT state. In this way, it is possible to select which RT state to shift to while considering not only the game time that can be played thereafter but also the possessed medals and psychological status at that time, and the repetitive game is monotonous It is possible to suppress this.

  Furthermore, the exit rate in the case where the game is performed by always shifting to the first RT state after the end of the BB state, and the exit rate in the case of performing the game by always shifting to the second RT state after the end of the BB state are almost equal. The winning probabilities of each combination in each gaming state and the number of games that can be executed in each RT state were determined so as to be equal. By adopting such a configuration, the player can select which RT state to shift to, so that the player can enjoy the game in each RT state, while having the intention of having a plurality of RT states. It is possible to suppress the dilution. That is, between the exit rate in the case where the game is performed by always shifting to the first RT state after the end of the BB state, and the exit rate in the case of performing the game by always shifting to the second RT state after the end of the BB state This is because if there is a difference, it is assumed that unless there are special circumstances, it is assumed that the game will be executed with the expectation that it will be possible to have more medals by shifting to the RT state where the rate is higher.

  In the right reel 32R, when the right stop switch 44 is operated at a timing at which the “red 7” symbol as the second re-game symbol can reach the predetermined position, the “white 7” symbol as the third re-game symbol. Does not reach the predetermined position, and when the right stop switch 44 is operated at a timing at which the “white 7” symbol can reach the predetermined position, the “red 7” symbol does not reach the predetermined position. The “Red 7” symbol and the “White 7” symbol are arranged apart from each other. By adopting such a configuration, if the player who desires the transition to the first RT state operates the right stop switch 44 at a timing at which the “red 7” symbol can be reached on the active line where the winning is established, When the second regame is won, the second regame prize can be established, and when the third regame is won, the establishment of the third regame prize can be avoided. Similarly, if the player who wishes to enter the second RT state operates the right stop switch 44 at a timing at which the “white 7” symbol can be reached on the active line where the winning is achieved, the third replay The third re-game winning can be established when the second re-game is won, and the second re-game winning can be avoided when the second re-game is won. Therefore, in the situation where the second regame or the third regame is won, it is possible to avoid that the player mistakenly establishes a replay prize that shifts to the RT state on the side that the player does not want. It becomes.

  In the situation where the second regame or the third regame is won, the replay winning prize corresponding to the winning combination can be established through the upper lamp 63 or the auxiliary display unit 65. With this configuration, in each game won in the second replay or the third replay, it is possible to allow the player to select whether or not to make a corresponding replay prize and shift to the RT state. Therefore, it is possible to suppress the dilution of the impression of actively participating in the game among the repeated games.

  The RT preparation state is configured to end when either the second re-game prize or the third re-game prize is established or BB is won. By adopting such a configuration, it is possible to realize the transition of the gaming state in a form that matches the player's intention. For example, if a player who does not want to enter the RT state or a player who is unable to decide which RT state to enter, the corresponding re-game prize will be established when the second re-game or the third re-game is won. This is because the game in the RT ready state can be continued by avoiding the above. In addition, the player who has decided which RT state to shift to continues the game in the RT ready state while expecting to win the replay to shift to the desired RT state, and This is because it is possible to shift to the RT state desired by establishing a corresponding re-game winning prize at the stage of winning.

  In the RT preparation state, the probability of winning the second replay is equal to the probability of winning the third replay. Which RT state the player wants to enjoy is considered to vary depending on the player or depending on the situation at the time. Therefore, by adopting such a configuration, the player who wants to enjoy the game under the RT state It will be possible to enjoy the game. For example, when the probability of winning the second replay is higher than the probability of winning the third replay, a player who wants to enjoy the game under the second RT state wins the second replay. It is necessary to avoid the establishment of the second replay prize every time. For this reason, if a player frequently wins the second replay before winning the third replay, a player who wants to enjoy a game under the second RT state will play a game under the second RT state. This is because there is a possibility of giving up or reducing the willingness to play because the third replay is not won. In addition, when the player gives up the game under the second RT state and establishes the second re-game prize, the player feels as if the profit obtained under the second RT state has been lost. This is because there is a possibility of not being able to fully enjoy the games in Japan.

  Next, a second embodiment will be described. In the above embodiment, when the BB is not won, the RT preparation state continues until the second re-game winning or the third re-game winning is achieved. The RT preparation state is also completed when the game is executed a number of times. Hereinafter, only differences from the first embodiment will be described, and description of the same configuration as that of the first embodiment will be omitted.

  In the state transition process (step S716, see FIG. 18) in the BB state process, the RT preparation setting flag is set in the state information storage area 106c of the RAM 106, and the remaining game number counter provided in the state information storage area 106c is set to 10. Set the game state to the RT ready state.

  In the lottery process in the RT preparation state (see FIG. 12), the lottery table for the RT preparation state is selected in step S302, and the winning / failing determination of the combination is executed using the lottery table.

  The lottery table shown in FIG. 22 is a first lottery table selected under the RT preparation state of “Setting 3”. In the first lottery table, as in the first lottery table in the first embodiment, the second replay, the third replay, the watermelon, the bell, the cherry, Seven roles of BB are set. However, regarding the point value PV of the second replay and the third replay, the point value PV of the second replay and the third replay was 4488 in the first embodiment, respectively. A very high value of 27984 is set. Therefore, in the RT ready state in the present embodiment, the second replay is won with a probability of about 1/24 and the third replay is won with a probability of about 2.33. That is, in the RT ready state, the player wins the second replay or the third replay with a very high probability of about 1.17.

  Further, in the present embodiment, the in-preparation state process shown in FIG. 23 is executed instead of the in-preparation state process shown in steps S602 to S607 of the RT state process (see FIG. 17).

  In the preparatory state process, first, in step S801, based on the winning combination set in the payout determination process, it is determined whether or not a second re-game winning is achieved. If the second re-game winning is established, in step S802, the first RT start process is executed to shift the gaming state to the first RT state, and the preparation state process ends. In the first RT start process, the RT preparation setting flag stored in the state information storage area 106c of the RAM 106 is cleared and the first RT setting flag is set in the state information storage area 106c to set the gaming state to the first RT state. . Further, the value of the remaining game number counter provided in the state information storage area 106c is changed to 72.

  If it is determined in step S801 that the second regame prize is not established, the process proceeds to step S803, and whether or not the third regame prize is established based on the winning combination set in the payout determination process. Determine whether. If the third re-game winning is established, a second RT start process is executed to shift the gaming state to the second RT state in step S804, and the preparatory state process is terminated. In the second RT start process, the RT preparation setting flag stored in the state information storage area 106c of the RAM 106 is cleared, and the second RT setting flag is set in the state information storage area 106c to set the gaming state to the second RT state. . Further, the value of the remaining game number counter provided in the state information storage area 106c is changed to 175.

  If neither the second re-game win nor the third re-game win is established in the RT preparation state, the process proceeds to step S805, and it is determined whether or not the BB win flag is set in the win flag storage area 106a. To do. If the BB winning flag is set, the process proceeds to step S806, the RT preparation setting flag stored in the state information storage area 106c of the RAM 106 is cleared, and the value of the remaining game number counter is cleared to 0, Processing in the ready state is terminated. On the other hand, if the BB winning flag is not set, 1 is subtracted from the value of the remaining game number counter in step S807, and it is determined whether or not the value of the remaining game number counter is 0 in step S808. If the value of the remaining game number counter is 0, the RT preparation setting flag is cleared in step S806, and the processing in the preparation state is ended. If the value of the remaining game number counter is not 0, the ready state process is terminated without clearing the RT preparation setting flag.

  In other words, the RT ready state ends when the second re-game prize or the third re-game prize is established, when BB is won, and when ten games are executed under the RT ready state. . Therefore, if the game is executed 10 times in the RT ready state and neither the second regame prize nor the third regame prize is established, the normal state is entered without entering any RT state. It will return.

  According to the present embodiment, in addition to the effects in the first embodiment described above, the following excellent effects are achieved.

  The configuration is such that the RT preparation state ends when the game is executed 10 times in the RT preparation state without establishing both the second re-game winning and the third re-game winning. With such a configuration, when the second regame or the third regame is won, it is possible to strongly urge the player to select whether or not to establish a corresponding regame prize. This is because if the game is not won in either the second replay or the third replay in the subsequent game, the game state shifts to a normal state that is disadvantageous to the player. As a result, when a re-game that wins the RT state on the side that the player does not want is won, the corresponding re-game winning is established although it is not originally desired, and the game state is advantageous for the player. Otherwise, enjoy the game in the RT state, or avoid the establishment of the corresponding re-game win, and accept the risk of shifting to the normal state, and then shift to the RT state on the side you want It is possible to make the player select whether to expect to win the replay.

  The second replay winning probability and the third replay winning probability under the RT ready state are set to the same winning probability as about 1/24. By adopting such a configuration, it is expected that when the game is executed 10 times in the RT preparation state, the second replay and the third replay are won by 4.27 times each. Therefore, even if the upper limit is set for the number of games that can be executed in the RT ready state, the chance that the game state returns to the normal state as a result of not winning the replay corresponding to the RT state desired by the player is reduced. It becomes possible to make it.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (1) In the first embodiment, when the BB is not won in the RT preparation state, the RT preparation state is continued until the second re-game winning or the third re-game winning is established. Such a configuration is changed. For example, the RT preparation state is terminated when the total number of wins for the second replay or the third replay reaches a predetermined number. Even in such a configuration, the RT preparation state continues until the predetermined number of times, so that the same operational effects as in the first embodiment can be obtained. However, it is desirable to set a plurality of times as the predetermined number. If it is once, if the player wins the replay corresponding to the RT state that the player does not want to shift, the corresponding replay winning will be established and the player will transition to the RT state that he / she does not want This is because the player is allowed to select whether to shift to the normal state while avoiding establishment of the re-game winning.

  (2) In each of the above embodiments, the second regame and the third regame can be won only when the RT preparation state is entered, but the second regame and the third replay are added to the normal state lottery table. Needless to say, the index value IV and the point value PV corresponding to the replay may be set so that the second replay and the third replay can be won even in the normal state. In the first embodiment, the RT ready state may not be provided, and the second regame and the third regame may be won in the normal state.

  (3) In each of the above-described embodiments, the RT preparation state is shifted to after completion of the BB state. However, RT preparation is performed when a predetermined number of games (for example, 100 times) are executed after the BB state ends. It is good also as a structure which shifts to a state, and when a RT ready state combination is set as a combination to be determined to be successful and the RT ready state combination is won (or when a corresponding winning is established), the state shifts to the RT ready state. It is good also as a structure.

  (4) In each of the above embodiments, the description has been given of the configuration including two types of RT states, the first RT state and the second RT state, as the gaming state in which the winning probability of the first replay is higher than the normal state. It is good also as a structure provided with the RT state more than a kind. Further, in a configuration including three or more types of RT states, a configuration including an RT state that can be selected by the player and an RT state that cannot be selected by the player may be employed. As an RT state that the player cannot select, specifically, an RT combination that is awarded a prize regardless of the operation timing of the stop switches 42 to 44 is set.

  (5) In each of the above embodiments, when the second re-game prize or the third re-game prize is established, the re-game benefit and the privilege to shift to the corresponding RT state are provided. It is good also as a structure to which only the privilege which transfers to RT state to give is given, and the structure to which the privilege which shifts to the RT state corresponding to the privilege to which a predetermined number of medal | token payout is provided is good. Moreover, it is good also as a structure to which the privilege which transfers to RT state corresponding after changing to a predetermined | prescribed game state is provided. Specifically, it is configured such that a privilege for shifting to the corresponding RT state after shifting to the BB state is given.

  (6) In each of the above embodiments, when the gaming state shifts to the first RT state or the second RT state, the player has a greater degree of advantage than the normal state. It is good also as a structure to become small. Even in the case of such a configuration, if the player can select whether to shift to the first RT state or the second RT state through which operation is executed, the player can be selected. In addition to actively participating in the game, it is possible to suppress the dilution of the impression of actively participating in the game among repeated games.

  For example, when the transition is made to the first RT state, the re-game winning probability is about 1/7. When the transition is made to the second RT state, the re-game winning probability is about 1/6. The game winning probability is approximately halved, and in each RT state, it is expected that the medal owned by the player will decrease every time one game is played, and in the normal state, the medal owned by the player plays one game. The configuration is expected to increase every time. The first RT state is ended when 300 games are executed or BB is won, and the second RT state is ended when 500 games are executed or BB is won. . In addition, when the game is played 500 times by shifting to the first RT state, the expected value for the increase in owned medals is higher than when the game is played 500 times by shifting to the second RT state. . In such a configuration, if there is confidence in winning the BB within 300 games after the end of the BB state, for example, the state may be shifted to the second RT state. This is because, when BB is actually won, more medals can be owned as compared with the case where the state is shifted to the first RT state. On the other hand, a player who is not confident of winning BB may shift to the first RT state instead of the second RT state. This is because, if the BB is not won even if the game is actually performed 500 times or more, more medals can be owned as compared to the case of shifting to the second RT state. In this way, it is possible to select which RT state to shift to while considering not only the game time that can be played thereafter but also the possessed medals and psychological status at that time, and the repetitive game is monotonous It is possible to suppress this.

  (7) In each of the above embodiments, the difference in the winning probability of the first replay is configured to change the player's degree of advantage in each game state of the normal state, the first RT state, and the second RT state. However, in addition to this, a configuration may be used in which the player's degree of advantage in each gaming state is changed by providing a difference in the winning probability of a small role such as a bell.

  (8) In each of the above embodiments, when the first RT state and the second RT state are compared, the number of games that can be executed, the first replay winning probability, and the probability of losing are different. Only one of them may have a different configuration. In short, the first RT state and the second RT state may be a gaming state that is more advantageous to the player than the normal state and is not the same.

  (9) In each of the above embodiments, the probability of winning the second replay and the probability of winning the third replay are the same, but they may not be equal. In the first embodiment, the probability of winning the second replay or the third replay in the RT ready state is equal to the probability of winning the first replay in the normal state. However, the configuration may be such that the probability of winning the second regame or the third regame is higher than the probability of winning the first regame under the normal state. With such a configuration, it is possible to suppress a decrease in the number of medals owned by the player under the RT preparation state.

  (10) In each of the above-described embodiments, by selecting which of the “red 7” symbol and the “white 7” symbol is to be operated, the second regame or the third regame is selected. Although it is configured to be able to select whether or not a re-game winning corresponding to winning is made, the stop switch operated at the time of the selection may be the left stop switch 42 or the middle stop switch 43 There may be. For example, the second replay prize is established when the red line is stopped along with the “red 7” symbol, the “replay” symbol, and the “replay” symbol in order from the left on the active line, and “white 7” in order from the left on the active line. When the symbols, “replay” symbols, and “replay” symbols are stopped side by side, the third replay winning prize is established. . In such a configuration, the second replay or the third regame is won by selecting which of the “red 7” symbol and the “white 7” symbol is to be operated. It is possible to select whether or not to establish a re-game winning corresponding to the case.

  (11) In each of the above-described embodiments, by selecting which of the “red 7” symbol and the “white 7” symbol is to be operated, either the first RT state or the second RT state is selected. Although it is configured to be able to select whether to shift to the gaming state (which transition to which RT state should be avoided), the configuration is not limited to this configuration, and the configuration in which the player can select the RT state to be shifted to If it is good. For example, when the left stop switch 42 is operated as the first stop command, the second re-game winning is established, and when stop switches 43 and 44 other than the left stop switch 42 are operated as the first stop command. It is assumed that the third replay prize is established. In such a configuration, if the stop switches 43 and 44 other than the left stop switch 42 are operated as the first stop command in a situation where the second regame is won, the transition to the first RT state is avoided. If the left stop switch 42 is operated as the first stop command in a situation where the third replay is won, the transition to the second RT state can be avoided.

  (12) In each of the above embodiments, the RT state is selected by operating the right stop switch 44, but the configuration may be selected by operating the middle stop switch 43 and the right stop switch 44. It is good also as a structure to select through operation of all the stop switches 42-44.

  (13) In each of the above-described embodiments, the right reel 32R has a section (No. 19 to No. 7) in which the “red 7” symbol can be stopped at a predetermined position and a “white 7” symbol at a predetermined position. The “red 7” symbol and the “white 7” symbol are arranged in such a manner that a zone that can be stopped at (No. 8 to No. 18) is formed. You may provide the section which can be made to reach a predetermined position together with the “white 7” symbol. However, in such a configuration, when winning the second replay or the third replay and avoiding the establishment of the corresponding replay win, the winning symbol will not reach the active line where the win is established. Therefore, it is necessary to change the target symbol according to the winning combination.

  (14) In each of the above embodiments, the second re-game winning is established when stopping alongside the “replay” symbol, the “replay” symbol, and the “red 7” symbol in order from the left on the active line. In order from the left, the 3rd regame winning is established when stopped alongside the “Replay” symbol, “Replay” symbol, and “White 7” symbol. It is not limited and is arbitrary. For example, as in the case of cherry winning, when the “red 7” symbol of the right reel 32R stops on the active line, the second re-game winning may be established regardless of the result of stopping the other reels 32L and 32M. good.

  (15) In each of the above embodiments, for the middle reel 32M and the right reel 32R, the “replay” symbol is given a role as the second replay symbol and a role as the third regame symbol. Similar to the right reel 32R, the second replay symbol and the third regame symbol may be different.

  (16) In each of the above embodiments, for the middle reel 32M and the right reel 32R, the “replay” symbol is given a role as the second replay symbol and a role as the third regame symbol. The “watermelon” symbol may have a role as the second replay symbol and a role as the third replay symbol, or the “bell” symbol may have a role as the second regame symbol and the third replay symbol. Needless to say, it may be configured to provide a role as a symbol.

  (17) In each of the above-described embodiments, in the right reel 32R, the second replay symbol and the third replay symbol are arranged so as to be separated from each other by four symbols or more on the side where the reel rotates. When the right stop switch 44 is operated to stop the symbol at a predetermined position, the other replay symbol does not reach the predetermined position. This is an example in the case of a slot machine in which the maximum number of slips that can be slid on a predetermined specified time is 4 symbols. In the case of a slot machine having a different maximum number of slips, each replay symbol may be arranged apart from the “(maximum number of slips on which the reel can slide)” symbol or more.

  (18) In each of the embodiments described above, an increase in medals is expected every time one game is played when the game is shifted to the first RT state, and a decrease in medals is expected every time one game is played when the game is shifted to the second RT state. However, a configuration in which an increase in medals is expected every time one game is performed even when the game is shifted to any RT state, or one game is played even when the game is shifted to any RT state. A configuration in which a decrease in medals is expected every time may be adopted. Even in the case of these configurations, each of the above implementations can be performed if the expected value of medal payout per game under the first RT state is higher than the expected value of medal payout per game under the second RT state. The same effects as those of the embodiment can be obtained.

  (19) In each of the above embodiments, the degree of advantage per game is different between the first RT state and the second RT state. That is, only the number of games that can be executed under the RT state is different between the first RT state and the second RT state. However, in such a configuration, since it is considered that a player who can execute a game for a long time will always select the second RT state and execute the game, the intention of providing a plurality of RT states is rare. There is a concern about the possibility of becoming.

  (20) In each of the above embodiments, the game is played when the game is played by always shifting to the first RT state after the end of the BB state, and the game is performed by always shifting to the second RT state after the end of the BB state. In this case, the output rate is almost equal to the output rate, but a different configuration may be used. However, in such a configuration, if a player wishes to end the game with more medals, the player always executes the game by selecting the RT state with the higher turnout rate. Therefore, there is a concern that the intention of providing a plurality of RT states may be diluted.

  (21) In each of the above-described embodiments, the description has been given of the configuration including the execution of the predetermined number of games and the winning of BB as the RT condition termination conditions. However, the predetermined number of games were executed. Only in some cases, the configuration may be such that the RT state ends, or instead of winning the BB, a configuration in which a BB winning is established as an end condition. Moreover, it is good also as a structure which performs the lottery of whether RT state is complete | finished under RT state, and terminates RT state when the said lottery is won. For example, in the first RT state, the end lottery that is won in 1/72 is executed every game, and in the second RT state, the end lottery that is won in 1/175 is executed every game. In such a configuration, 72 games can be expected to be played by the end of the first RT state, and 175 games can be expected to be played by the end of the second RT state. Therefore, it can be expected that the same effects as those of the above embodiments can be obtained. In addition, it is good also as a structure which performs an end lottery every time a predetermined number of games are performed instead of the structure which performs an end lottery every game, and when a predetermined winning combination is won or a predetermined winning is achieved It is good also as a structure which performs an end lottery. Alternatively, the RT state may be terminated when a predetermined winning combination is won or when a predetermined winning is achieved.

  (22) In each of the above embodiments, when winning the second replay or the third replay, the configuration suggests a winning mode that can be established by the upper lamp 63 or the auxiliary display unit 65. Further, a configuration suggested by a predetermined probability may be used, or a configuration not suggested may be used. However, in the case of these configurations, when the stop switch is operated aiming at one replay symbol as in the symbol arrangement of the right reel 32R in each of the above embodiments, the other replay symbol is established. It is desirable to arrange the second regame symbol and the third regame symbol apart so as not to stop on the active line. This is because in a situation where it is not suggested that the player has won the second replay or the third regame, there is a possibility that the player may erroneously establish a regame winning that is intended to avoid winning the winning. .

  (23) In addition to a single winning combination that will be elected only for the second replay or a single winning role that will be elected only for the third replay, in addition to a multiple winning combination that will be selected for both the second replay and the third replay. May be set. In the above-described embodiments, when the multiple winning combination is set, it is possible to select whether or not a winning combination corresponding to winning a single winning combination is established. It is possible to select whether to win a prize.

  In addition, a configuration in which a plurality of winning combinations are set and the player selects whether to establish a second re-game prize, to establish a third re-game prize, or to avoid any prize-winning. It is also possible to do. For example, the 12th “white 7” symbol of the right reel 32R is changed to a symbol other than the “red 7” symbol. In such a configuration, when the right stop switch 44 is operated when the 8th to 10th symbols of the right reel 32R have reached the effective line where the winning is established, “red 7” is displayed on the effective line. The "" and "White 7" symbols cannot be stopped, and any winnings can be avoided.

  The multiple winning combination will be described using the lottery process in each of the above embodiments as an example. When the winning combination is determined with a predetermined index value, both the second regame winning flag and the third replay winning flag are set. To do. In such a configuration, both the second re-game and the third re-game are won by a single success / failure determination. Further, in the configuration in which a numerical range for winning is set in advance for each combination, and the winning flag of the combination corresponding to the numerical range to which the random number acquired when the start lever 41 is operated is set, the second re-game winning The numerical range is set so that at least a part of the numerical range in which the flag is set and the numerical range in which the third replay winning flag is set overlap.

  In each of the embodiments described above, in the RT preparation state, the first multiple winning combination winning both the first replay and the second regame, and the second winning both the first replay and the third replay. It is good also as a structure which sets multiple winning combination. In such a configuration, the first regame prize can be established when the player avoids the establishment of the second regame prize or the third regame prize. Therefore, it is possible to prevent the player's owned medals from decreasing as a result of avoiding the establishment of the corresponding re-game winning when the second re-game or the third re-game is won.

  (24) In each of the above embodiments, it is assumed that the second regame winning or the third replay winning is established in the first game after the end of the BB state. However, considering the winning probabilities of the respective combinations The number of games expected to shift to the corresponding RT state is calculated, and the BB winning expectation is about 50% in the number of games in which the expected value of increase of owned medals is equal. The winning probability may be adjusted. Needless to say, instead of adjusting the BB winning probability, the winning probability of each combination and the number of medals to be paid out when winning a prize may be adjusted.

  (25) In each of the above embodiments, it is determined whether or not a start command is issued after three medals are betted. However, a start command is also issued after one or two bets are placed. Needless to say, it may be configured to determine whether or not the error has occurred. However, in the case of such a configuration, it is necessary to store in advance a lottery table and a sliding table corresponding to the betting situation.

  (26) In each of the above-described embodiments, as a privilege to be given, in addition to the privilege that the gaming state shifts and the privilege of replaying, the medal payout privilege is provided. However, the configuration is limited to this configuration. Any configuration may be used as long as it gives a player some kind of privilege. For example, a configuration in which a prize other than a medal is paid out instead of a medal to pay out a medal may be used. Further, in a slot machine that does not have an actual medal insertion or medal payout function and manages credits owned by a player, an increase in credited medals corresponds to provision of a privilege.

  (27) In each of the above embodiments, a slot machine having three reels arranged in parallel and having five lines as effective lines has been described. However, the present invention is not limited to this configuration. For example, five reels are arranged in parallel. Or a slot machine having seven effective lines.

  (28) Although the so-called A type slot machine has been described in each of the above embodiments, B type, C type, A type and C type composite type, B type and C type composite type, and further CT game The present invention may be applied to any slot machine such as a provided type, and it is apparent that the same effects as those of the above-described embodiment can be obtained in any case. In addition, examples of bonus winning in each type include BB winning, RB winning, SB winning, CT winning and the like.

  (29) In each of the above-described embodiments, an example in which the slot machine 10 is embodied has been shown. However, the present invention may be applied to a gaming machine in which a slot machine and a pachinko machine are combined. That is, in the slot machine, instead of the medal insertion and medal payout functions, a gaming machine having a ball insertion and ball payout function such as a pachinko machine may be used. If such a gaming machine is used in place of a slot machine, only a ball can be handled as a gaming value in the gaming hall. Therefore, the gaming value seen in the current gaming hall in which pachinko machines and slot machines are mixed is used. Problems such as the burden on equipment due to the separate handling of medals and balls and restrictions on the location of the gaming machine can be solved.
