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.

  In such a slot machine, as a gaming state advantageous to the player, in addition to the BB state that shifts when a BB winning is established, a replay time (hereinafter referred to as “RT”) in which the probability of winning a re-game is higher than the normal gaming state. ) State, and after the end of the BB state, the RT state is ended when a predetermined end condition is satisfied (for example, see Patent Document 1).

JP 2002-204854 A

  In some slot machines having the RT state, the RT state ends even when a BB is won in addition to the case where a predetermined number of games are played in the RT state. However, in the case where the RT state is configured to end by BB winning, there is a possibility that the player may reduce the game motivation by the winning timing of BB. This is because, for example, when a BB is won in a game immediately after the transition to the RT state, there is a possibility that the player may have an impression as if the player has lost the profits obtained under the RT state.

  The above problems are not limited to the slot machines as exemplified above, but also apply to slot machines in which the gaming state advantageous to the player such as the RT state ends when a special role such as RB is won. is there. In addition, this is a problem corresponding to other gaming machines in which a plurality of types of patterns are cyclically displayed and the cyclic display is terminated based on the subsequent operation of the stop operation means.

  The present invention has been made in view of the above-described circumstances and the like, and an object thereof is to provide a gaming machine capable of suppressing a player from diminishing his willingness to play a game.

According to the first aspect of the present invention, a circulation display unit that circulates and displays a plurality of types of patterns, a start operation unit that is operated to start the cyclic display of the patterns, a lottery unit that performs a lottery of a combination, and the patterns Based on the stop operation means operated to stop the circulation display of the winning combination and the winning symbol corresponding to the winning combination winning the lottery of the winning combination formed a predetermined combination at the effective position and stopped, In a gaming machine provided with a privilege granting means for granting a privilege to a player, a first game state transition means for shifting to the first game state, and a second game having a higher probability of winning the first role than the first game state Second gaming state transition means for transitioning to a state, first special gaming state transition means for transitioning to a first special gaming state based on winning a special role in the first gaming state, and the second gaming state smell And a second special gaming state transition means for shifting to the second special gaming state based on the winning of the special combination, the lottery means having a winning probability of the first combination in the second special gaming state. In the first special gaming state, the winning combination of the first combination in the first special gaming state or the second special gaming state is selected so that the winning combination of the first combination is higher than the winning probability of the first combination. In such a case, if it is possible to establish a first winning combination corresponding to the first winning combination, the first winning combination is established, and if it is impossible to establish the first winning combination, a second winning combination is achieved. If the first combination is not won in the first special game state or the second special game state, the predetermined combination prize is awarded if the circulation display unit is controlled to stop the circulation display unit so that a winning is established. So that it can be established A second stop control means for stopping and controlling the ring display means; a first giving means for giving a predetermined number of game media when the predetermined winning combination is established; and a predetermined number when the second winning prize is established.

  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 with reference to 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, “bell” symbol (for example, 20th of left reel 32L), “replay” symbol (for example, 19th of left reel 32L), “red 7” symbol (for example, 18th of left reel 32L), “White 7” symbol (eg, 17th on left reel 32L), “Youth” symbol (eg, 16th on left reel 32L), “Cherry” symbol (eg, 12th on left reel 32L), “BAR” symbol There are eight types (for example, the ninth of the left reel 32L) and the “watermelon” symbol (for example, the eighth 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 the slot machine 10, a total of four combination lines are set so as to connect positions where the symbols of the reels 32L, 32M, and 32R are visible. More specifically, as shown in FIG. 7A, the first line L1 connecting the upper symbol of the left reel 32L, the middle symbol of the middle reel 32M, the upper symbol of the right reel 32R, and the upper symbol of the left reel 32L, The second line L2 connecting the middle design of the middle reel 32M and the lower design of the right reel 32R, the third line L3 connecting the middle design of each reel 32L, 32M, 32R, and the lower design and middle reel of the left reel 32L A fourth line L4 connecting the middle symbol of 32M and the upper symbol of 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.

  As the small role winning in which medals are paid out, there are a first small role winning to a seventh small role winning. When the “cherry” symbol of the middle reel 32M stops on the active line, three medals are paid out as the first small role winning regardless of the number of medals bet. In the case of the first small winning combination, the symbols that stop on the active line for the left reel 32L and the right reel 32R may be any symbols. In other words, if the combination of the “cherry” symbol of the middle reel 32M and any symbol of the left reel 32L and the right reel 32R stops on the active line, it can be said that the first small winning combination is established. Here, when all of the first line L1 to the fourth line L4 are validated, the middle stage of the middle reel 32M is a position where four valid lines overlap, so that the “cherry” symbol is placed on the middle stage of the middle reel 32M. Is stopped, the first small role winning is established on the four active lines, and as a result, 12 (= 3 × 4) medals are paid out. When the “watermelon” symbols on the reels 32L, 32M, and 32R are stopped on the active line, six medals are paid out as the second small winning combination regardless of the number of medals bet. When the “bell” symbol of each reel 32L, 32M, 32R stops on the active line, as a third small role winning, if three medals are bet, nine medals are paid out. If medals are bet, 15 medals are paid out. When the “bell” symbol of the left reel 32L and the right reel 32R and the “replay” symbol of the middle reel 32M are stopped on the active line, the fourth small role prize is 2 regardless of the number of medals bet. A medal is paid out. If the “white 7” symbol on the left reel 32L, the “replay” symbol on the middle reel 32M, and the “bell” symbol on the right reel 32R are stopped on the active line, a medal is awarded as the fifth small role prize. One medal is paid out regardless of the number of bets. If the “Red 7” symbol on the left reel 32L, the “Replay” symbol on the middle reel 32M, and the “Bell” symbol on the right reel 32R are stopped on the active line, a medal is awarded as the sixth small part prize. One medal is paid out regardless of the number of bets. If the “BAR” symbol on the left reel 32L, the “Replay” symbol on the middle reel 32M, and the “Bell” symbol on the right reel 32R stop on the active line, One medal is paid out regardless of the number of bets.

  There are first to third re-game prizes as prizes to which a re-game privilege that allows the next game to be played without inserting medals is given. When the “replay” symbol of each reel 32L, 32M, 32R stops on the active line, it becomes the first replay prize, and the “young” symbol of the left reel 32L, the “bell” of the middle reel 32M and the right reel 32R. When the symbol stops on the active line, the second replay prize is awarded, and the “replay” symbol of the left reel 32L and the middle reel 32M and the “white 7” symbol of the right reel 32R are effective lines. If it stops above, it becomes the third replay prize.

  State transition winnings in which only the game state transition is performed include a first CB winning and a second CB winning.

  When the “red 7” symbol of each reel 32L, 32M, 32R stops on the active line, the first CB wins, and when the “BAR” symbol of each reel 32L, 32M, 32R stops on the active line. Is the second CB prize. When these CB winnings are established, the gaming state shifts to the CB 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 fifth small role symbol is a combination of symbols that become the fifth small role winning combination, that is, a combination of “white 7” symbol, “replay” symbol, and “bell” symbol. The symbols of the reels 32L, 32M, and 32R corresponding to the winnings are also referred to as winning symbols. For example, the fifth small role symbol is a “white 7” symbol in the left reel 32L, a “replay” symbol in the middle reel 32M, and a “bell” symbol in 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.

  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.

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 FIGS. 10 to 17 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. The RAM 106 has a memory for temporarily storing various data, a winning flag storage area 106a for storing a lottery result of a combination, and stop information used when stop control of each reel 32L, 32M, 32R is performed. In addition to the stop information storage area 106b for storing the game information, the status information storage area 106c for storing the game status such as the CB 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 cut off by a power failure process (see FIG. 10), and 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 is completed. If the transmission is not completed, the present 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 S213 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 or not any of the first re-game win to the third re-game win 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 changing the number of bets 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 the prescribed number. If the bet number has not reached the prescribed number, the process returns to the start waiting process in step S204. Of the processing, the processing after the sensor abnormality confirmation processing is performed. Specifically, in step S205, if the CB setting flag indicating that the current gaming state is the CB state is not set in the state information storage area 106c, it is determined whether or not the number of bets has reached 3. When the CB setting flag is set in the state information storage area 106c, it is determined whether or not the bet number has reached 2. 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, an effective line setting process is performed in step S207. In the effective line setting process, when the CB setting flag is not set in the state information storage area 106c, as shown in FIG. 7A, all combination lines of the first line L1 to the fourth line L4 are set as effective lines. When the CB setting flag is set in the state information storage area 106c, the two combination lines of the first line L1 and the fourth line L4 are set as effective lines as shown in FIG. 7B. In the subsequent step S208, the medal path switching solenoid 46a is switched to a non-excited state to prohibit bet acceptance. Thereafter, the lottery process in step S209, the reel control process in step S210, the medal payout process in step S211, the RT state process in step S212, and the CB state process in step S213 are executed in order, and the process returns to step S203.

  Next, the lottery process in step S209 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. In the slot machine 10, the first CB win or the second CB win is established under the CB state A and the RT state which are shifted when the first CB win or the second CB win is established under the normal game state, the RT state, or the normal game state. There are four game states of CB state B that shift to the case. In step S302, the current gaming state of the slot machine 10 is determined based on the setting flag set in the state information storage area 106c, and a lottery table corresponding to the gaming state is selected. For example, when the setting flag is not set in the state information storage area 106c, it is determined that the current gaming state is the normal gaming state, and the normal gaming state lottery table is selected. Further, in this slot machine 10, a six-stage winning probability from “Setting 1” to “Setting 6” is prepared in advance, and a setting key is inserted into the setting key insertion hole to perform an ON operation and a predetermined operation is performed. Thus, 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 gaming state lottery table selected in the “setting 3” normal gaming state. An index value IV is set in the lottery table, and each index value IV is uniquely associated with a winning combination and a point value PV.

  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, it is determined whether or not the combination corresponding to the index value IV is correct. In the combination determination, it is determined whether or not the determination value DV exceeds 65535. If it exceeds 65535, the process proceeds to step S306, and the winning flag 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 = 1, in step S306, a winning flag indicating that the first replay has been won is set in the winning flag storage area 106a.

  By the way, a winning flag indicating that the set winning flag has won the first CB (hereinafter referred to as “first CB winning flag”) or a winning flag indicating that the second CB has been won (hereinafter referred to as “second CB winning flag”). Otherwise, the winning flag set in the winning flag storage area 106a is reset after the game in which the corresponding winning flag is set (see S203 of the normal process). On the other hand, when the winning flag is the first CB winning flag or the second CB winning flag, these winning flags are reset as one of the conditions that the corresponding CB winning is established. That is, the first CB winning flag and the second CB winning flag may be valid over a plurality of games. In step S306 in the state where the first CB winning flag or the second CB winning flag is carried over, if the current index value IV is 1, 4 to 10, the winning flag corresponding to the index value IV is set and the current index value is set. If IV is 2 or 3, the corresponding winning flag is not set. In other words, in a game in which the first CB winning flag or the second CB winning flag is carried over, when winning a role other than the first CB and the second CB, the corresponding winning flag is set, while the first CB or the second CB is won. In that case, the corresponding winning flag is not set.

  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. By the way, when determining whether a winning combination is won using the lottery table shown in FIG. 13, the probability of winning the first replay is about 1 / 7.3, and the probability of winning the first small role is about 200. 1/100, the chance of winning the 2nd small role is about 1/100, the probability of winning the 3rd small role is about 1/10, the probability of winning the 4th small role is about 100 minutes 1. The probability of winning the fifth small role is about 1/200, the probability of winning the sixth small role is about 1/200, the probability of winning the seventh small role is about 1/200, The probability of winning the first CB is about 1/300, and the probability of winning the second CB is about 1/300. In addition, the probability of losing no winning combination is about 1 / 1.4.

  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, the process proceeds to step S309, and it is determined whether or not the CB setting flag is set in the state information storage area 106c. If the CB setting flag is not set, a lottery result command is set in step S311. 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. If the lottery result command is set, stop information setting processing for setting stop information for reel stop control is performed in step S312, and the lottery processing is terminated. In the stop information setting process, for example, when a winning flag indicating that a plurality of roles have been won is set, such as when the first replay is won in a situation where the first CB winning flag is carried over, the following stop is shown: Set the information. Corresponds to the winning flag when the winning flag indicating that the first CB or the second CB is won and the winning flag indicating that one of the first re-game to the third re-game is won are set. Stop information for establishing a replay winning is set. If the winning flag indicating that the first CB or the second CB has been won and the winning flag indicating that one of the first small role to the seventh small role has been set are set, it corresponds to the winning flag. Stop information for establishing a CB winning is set. When a winning flag indicating that one of the first replay to the third replay has been won and a winning flag indicating that one of the first small role to the seventh small role has been set are set Is set to stop information for establishing a re-game winning corresponding to the winning flag.

  Next, the reel control process of step S210 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, in step S402, 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 one of the stop switches 42 to 44 has been operated, the process proceeds to step S403 to determine 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 S402 and waits until any of the stop switches 42 to 44 is operated. If a stop command is generated, a stop command command is set in step S404. Here, the stop command command is a command transmitted to the display control device 81 in order to grasp which stop switch is operated to generate the stop command. When the stop command command is set, stop control processing shown in steps S405 to S411 is performed to stop the rotating reel.

  In step S405, the symbol number of the symbol that has reached the base point position (lower in this embodiment) at the timing when the stop switch is operated is confirmed. Specifically, the symbol number of the reaching symbol reaching the base point position is confirmed by the number of excitation pulses output from the time when the detection signal of the reel index sensor is input. In the subsequent step S406, the number of reels to be stopped this time is calculated based on the stop information stored in the stop information storage area 106b. 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. Therefore, in step S406, based on the stop information stored in the stop information storage area 106b, one of 0 to 4 is calculated as the number of slips. Thereafter, in step S407, the calculated number of threads is added to the symbol number of the reaching symbol, and the symbol number of the stop symbol that is actually stopped at the base point position is determined. In step S408, 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 S409. Do. Thereafter, in step S410, 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, stop information second setting processing is performed in step S411, and the process returns to step S402.

  Here, the stop information second setting process is a process of changing the stop information stored in the stop information storage area 106b of the RAM 106 after the reels are stopped. In the stop information second setting process, the stop information is changed based on the set winning flag and the stop appearance of the stopped reel. For example, in the situation where the 1st CB and the 2nd small part are elected, if the 8th “watermelon” symbol of the left reel 32L is stopped in the upper stage, there is still room for the 2nd small part winning. On the other hand, there is no room for the first CB winning. Accordingly, in the stop information second setting process, stop information for stopping the second small role symbol on the active line instead of the first CB symbol is set as stop information of the middle reel 32M and the right reel 32R.

  Returning to the description of the reel control process, if it is determined in step S410 that all the reels 32L, 32M, and 32R are stopped, a payout determination process is performed in step S412. The payout determination process is a process of setting the payout number of medals as one of the conditions that the combination of winning symbols is arranged on the 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 is established, it is further determined whether or not the winning combination is associated with the winning flag set in the winning flag storage area 106a. If the winning winning combination corresponds to the winning flag, the winning winning combination and the number of payouts corresponding to the winning winning combination are set in the payout information storage area provided in the RAM 106. On the other hand, if the winning combination does not correspond to the winning flag, an abnormality occurrence process for notifying the occurrence of an error is performed while the slot machine 10 is set in an error state. Such an error state is maintained until the reset switch 72 is operated. When the payout determination process is completed, a winning result command is set in step S413 to cause the display control device 81 to recognize the winning combination in the current game, and the reel control process is ended.

  Next, the outline of the medal payout process in step S211 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. If the number of payouts is 0, it means that it has been determined in the previous payout determination process that a small winning combination has not been established. In such a case, based on the winning combination set in the payout determination process, it is determined whether any of the first regame winning to the third regame winning is achieved. If no re-game winnings have been established, the medal payout process is terminated as it is. Then, 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 is paid 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. Further, when the CB setting flag is set in the status information storage area 106c, the payout number is subtracted from the value of the remaining payout number counter, which will be described later, and the remaining payout number displayed on the remaining payout number display unit 61 is displayed. Perform the subtraction process.

  The RT state process in step S212 will be described later, and the CB state process in step S213 will be described based on the flowchart of FIG.

  Prior to the description of the CB state process, the CB state will be described. In the CB state, the stop mode of the left reel 32L changes. Specifically, when the left stop switch 42 is operated, a stop mode in which the reaching symbol reaching the base point position is stopped as it is, and a stop mode in which the left reel 32L is stopped after sliding for one symbol, These are only two patterns of stop modes. The middle reel 32M and the right reel 32R remain in the five-pattern stop mode. Also, the CB state ends when the number of medals paid out reaches a predetermined number (specifically, 268).

  In the CB state process, first, in step S501, it is determined whether or not the CB setting flag is set in the state information storage area 106c. If the CB setting flag is not set, it is determined that the current gaming state is not the CB state, and CB determination processing shown in steps S502 to S506 is performed.

  In the CB determination process, it is determined in step S502 whether the first CB winning flag or the second CB winning flag is set. If any of the CB winning flags is set, the process proceeds to step S503, and whether or not the first CB winning or the second CB winning is established based on the winning winning combination set in the previous payout determination process. judge. If any CB winning is established, the CB winning flag set in the winning flag storage area 106a is cleared in step S504, and the CB setting flag is set in the state information storage area 106c in step S505. . When the CB setting flag is set, the gaming state shifts to the CB state. In subsequent step S506, 268 is set in the remaining payout counter for counting the remaining number of medals that can be paid out in the CB state provided in the state information storage area 106c, and 268 is set in the remaining payout number display portion 61. Process to be displayed. Thereafter, a status command is set in step S507, and this process ends. Here, the state command is a command transmitted to the display control device 81 in order to grasp the current game state, that is, the game state of the next game. In step S507, the status information storage area 106c is referred to, and a status command corresponding to the setting flag set in the status information storage area 106c is set.

  When the CB winning flag is not set (when step S502 is NO) or when the CB winning is not established (when step S503 is NO), the CB setting flag is not set at step S507. Sets the status command and ends this process.

  If it is determined in step S501 that the CB setting flag is set, it is determined in step S508 whether the value of the remaining payout number counter is zero. If it is not 0, it means that the number of medals paid out during the CB state has not reached the predetermined number and the end condition for the CB state is not satisfied, so a state command is set in step S507, The process ends. On the other hand, when the value of the remaining payout counter is 0, it means that the CB state end condition is satisfied, and therefore the CB state end process shown in steps S509 to S512 is performed. In the CB state end process, first, in step S509, the CB setting flag set in the state information storage area 106c is cleared. In a succeeding step S510, it is determined whether or not an RT setting flag is set in the state information storage area 106c. If the RT setting flag is not set, the RT setting flag is set in the state information storage area 106c in step S511, and then the process proceeds to step S512. If the RT setting flag is set, the process proceeds to step S512. move on. In step S512, 100 is set in the remaining game number counter provided in the state information storage area 106c and for counting the number of games played under the RT state. Thereafter, a status command is set in step S507, and the CB status process is terminated.

  As described above, in the slot machine 10, when the CB state ends, the RT setting flag is set in the state information storage area 106c, and the gaming state shifts to the RT state. In step S302 of the lottery process, it is determined that the current gaming state is the RT state based on the fact that only the RT setting flag is set in the state information storage area 106c, and the RT state lottery table is selected.

  FIG. 16 is an RT state lottery table selected in the “setting 3” RT state. In the RT state lottery table, ten index values IV are set as in the normal game state lottery table (see FIG. 13). When IV = 1, instead of the first replay as a winning combination. The second re-game and the third re-game are set, and 45875 is set instead of 8978 as the point value PV. In IV = 2 to 10, the same winning combination and point value PV as in the normal gaming state lottery table are set. In the case where the winning combination determination is made using the lottery table, the winning probabilities of the first CB, the second CB, the first small role to the seventh small role are equal to the winning probabilities in the normal gaming state. The first regame is not won, and the winning probabilities of the second replay and the third replay are about one-fourth. Since the winning probability of the first replay in the normal game state is about 1 / 7.3, the probability of being given a replay privilege is higher when shifting to the RT state than in the normal game state. Become. The probability of losing no winning combination will be about 1 / 6.5.

  When the second regame and the third regame are won, stop information is set in the stop information setting process and the stop information second setting process in order to establish a third regame prize. On the left reel 32L and the middle reel 32M, a “replay” symbol as the third replay symbol is arranged so that the interval between the symbols of the same kind is 4 symbols or less, and the symbols of the same kind are arranged on the right reel 32R. The “white 7” symbol, which is the third replay symbol, is arranged so that the interval is 4 symbols or less. For this reason, when the second regame and the third regame are won, the third regame prize is established regardless of the operation timing of the stop switches 42 to 44.

  Here, the RT state process of step S212 will be described based on the flowchart of FIG.

  In step S601, it is determined whether an RT setting flag is set in the state information storage area 106c. If the RT setting flag is not set, it means that the current gaming state is not the RT state, and thus this process is terminated as it is. When the RT setting flag is set, the process proceeds to step S602, and it is determined whether or not the first CB winning flag or the second CB winning flag is set in the winning information storage area 106a. If any CB winning flag is set, the process is terminated as it is. If any CB winning flag is not set, the remaining game number counter is decremented by 1 in step S603. At the same time, in step S604, it is determined whether or not the value of the remaining game number counter has become zero. If the value of the remaining game number counter is not 0, the present process is terminated. If the value of the remaining game number counter is 0, CB is set in the state information storage area 106c in step S605. It is determined whether or not the flag is set. If the CB setting flag is not set, it means that 100 games have been played in the RT state, so the RT setting flag is cleared in step S606, and this process ends. Further, when the value of the remaining game number counter becomes 0 in a situation where the CB setting flag is set (when both step S604 and step S605 are YES), the gaming state at that time is the CB state. Then, this process is terminated without clearing the RT setting flag.

  Here, game play in the CB state of the slot machine 10 will be described. The slot machine 10 has two game states, CB state A and CB state B, as the CB state, and the game state that shifts after the CB winning is established depending on the game state when winning the first CB or the second CB. It is going to change.

  When the first CB or the second CB is won in the normal gaming state, only the CB setting flag is set in the state information storage area 106c after the CB winning is established. In step S302 of the lottery process, it is determined that the current gaming state is the CB state A based on the fact that only the CB setting flag is set in the state information storage area 106c, and the lottery table for the CB state A is selected. To do.

  FIG. 18A is a CB state A lottery table selected in the CB state A of “setting 3”. In the CB state A lottery table, only one index value IV is set. When IV = 1, the first replay is set as the winning combination and 8978 is set as the point value PV. Yes. Further, as shown in FIG. 13, in IV = 1 of the normal gaming state lottery table, the first re-game is set as the winning combination and 8978 is set as the point value PV. In other words, when the first CB or the second CB is won in the normal gaming state, whether or not the first re-game is successful is determined in the CB state A with the same winning probability as that in the normal gaming state. In addition, in the lottery process (see FIG. 12) in the CB state A, when the determination of the success / failure of the first replay is completed, an affirmative determination is made in step S309 and all the small role winning flags, A winning flag indicating that all of the first small combination to the seventh small combination are won is set in the winning flag storage area 106a. For this reason, in the CB state A, the winning situation where all the small roles are won and the winning situation where all the small roles and the first replay are won are selected, and both roles are won. The winning situation that is not done does not occur.

  When the first CB or the second CB is won in the RT state, the RT setting flag is set in addition to the CB setting flag in the state information storage area 106c after the CB winning is established. In step S302 of the lottery process, it is determined that the current gaming state is the CB state B based on the CB setting flag and the RT setting flag being set in the state information storage area 106c. Select a table.

  FIG. 18B is a CB state B lottery table selected in the CB state B of “setting 3”. In the CB state B lottery table, only one index value IV is set. When IV = 1, the second replay and the third replay are set as the winning combination, and the point value PV 45875 is set. Further, as shown in FIG. 16, in the RT state lottery table, IV = 1, the second regame and the third regame are set as the winning combination, and 45875 is set as the point value PV. That is, when the first CB or the second CB is won in the RT state, whether or not the second regame and the third regame are determined in the CB state B with the same winning probability as the RT state is performed. In addition, in the lottery process in the CB state B (see FIG. 12), when the determination of whether or not the second regame and the third regame are finished, an affirmative determination is made in step S309 and all small roles are determined in step S310. The winning flag is set in the winning flag storage area 106a. For this reason, in the CB state B, the winning situation where all the small roles are won and the winning situation where all the small roles, the second replay and the third replay are won are either A winning situation that is not won by any of the roles will not occur.

  As described above, in the CB state, whether or not a winning combination is determined by taking over the role type to which the re-playing privilege in the gaming state when winning the first CB or the second CB and the winning probability thereof are taken over.

  Next, the reel stop control in the CB state will be described. As described above, in the CB state, the stop mode of the left reel 32L is a stop mode in which the reaching symbol reaching the base position is stopped as it is, and a stop mode in which the left reel 32L is stopped after sliding for one symbol, The two patterns are as follows.

  FIG. 19 is a diagram illustrating a correspondence relationship between a symbol that has reached the lower stage when the left stop switch 42 is operated in the CB state A and a stop mode (slip number) of the left reel 32L. For example, when the left stop switch 42 is operated while the 11th symbol of the left reel 32L reaches the lower stage, the left reel 32L is stopped without sliding, and the 11th “bell” Stop the symbol at the bottom. If the left stop switch 42 is operated when the 14th symbol of the left reel 32L reaches the lower stage, the left reel 32L is slid by one symbol and then stopped. ”Stop the symbol at the bottom.

  If all the small roles are won but the first replay is not won, stop information is set in the stop information setting process and the stop information second setting process so that the number of small roles that will win a prize increases. To do.

  The case where the left stop switch 42 is operated when the 17th symbol of the left reel 32L reaches the lower stage will be described as an example. When the left reel 32L is stopped without sliding, for example, This is the stop result shown in 20 (a). In the CB state, two combination lines of the first line L1 and the fourth line L4 are set as effective lines. Therefore, at the stop turn shown in FIG. 20A, the fifth small winning combination is won on the fourth line L4. Is established, that is, one small role winning is established. On the other hand, when the left reel 32L is stopped after being slid by one symbol, for example, the stop turn shown in FIG. In this stoppage, the fourth small part winning is established on the first line L1, and the sixth small winning combination is established on the fourth line L4, that is, two small winnings are established. Therefore, in the stop information setting process and the stop information second setting process, when all the small roles are won and the first replay is not won, the 17th symbol of the left reel 32L has reached the lower stage. At this time, if the left stop switch 42 is operated, stop information is set so that the left reel 32L slides by one symbol.

  On the left reel 32L, the “white 7” symbol which is the fifth small role symbol is arranged at the positions of No. 5, 13, and 17, and the “red 7” symbol which is the sixth small symbol symbol is the position of the 18th. The “BAR” symbol, which is the seventh small role symbol, is arranged at the 1st and 9th positions. Here, the interval between No. 1 “BAR” symbol and No. 5 “White 7” symbol is 3 symbols, and the interval between No. 5 “White 7” symbol and No. 9 “BAR” symbol is 3 symbols. The interval between the 9 “BAR” symbol and the 13 “White 7” symbol is 3 symbols, and the interval between the 13 “White 7” symbol and the 17 “White 7” symbol is 3 symbols, The interval between the 17th “white 7” symbol and the 18th “red 7” symbol is 0 symbol, and the interval between the 18th “red 7” symbol and the 1st “BAR” symbol is 3 symbols. That is, the fifth small role symbol, the sixth small role symbol, and the seventh small role symbol are arranged on the left reel 32L so as to have an interval of 3 symbols or less. In the CB state, effective lines are set at the upper and lower stages of the left reel 32L. Therefore, by arranging the above symbols on the left reel 32L so as to have an interval of 3 symbols or less, the operation timing of the left stop switch 42 is affected. Any one of the fifth small role symbol, the sixth small role symbol, and the seventh small role symbol can be stopped on the active line. The left reel 32L, except for positions 17 and 18, is one of the fifth small role symbol, the sixth small role symbol, the seventh small role symbol, the third small role symbol, and the fourth small role symbol. The “bell” symbols are arranged at intervals of one symbol. For the left reel 32L, effective lines are set at the upper and lower stages, that is, an effective line is set at a position separated by one pattern. Therefore, unless the 17th “white 7” symbol of the left reel 32L stops at the lower stage When any of the fifth small role symbol, the sixth small role symbol, and the seventh small role symbol stops on one of the active lines, the third small role symbol and the fourth small role symbol “Bell” symbol Stops on the other active line.

  The middle reel 32M is provided with a “replay” symbol, which is a fourth small role symbol to a seventh small role symbol so that the interval between the same symbol symbols is 4 symbols or less, and the right reel 32R has the same symbol symbol. The “bell” symbols as the fourth to seventh small symbols are arranged so that the distance between them is 4 symbols or less. Even in the CB state, the middle reel 32M and the right reel 32R can be stopped after sliding a maximum of four symbols. Therefore, in the stop information setting process and the stop information second setting process, when all the small roles are won but the first replay is not won, the fourth small role symbol regardless of the operation timing of the middle stop switch 43. Stop information is set so that the “replay” symbol as the seventh small role symbol stops on the active line, and the “bell” as the fourth small role symbol as the seventh small role symbol regardless of the operation timing of the right stop switch 44. Set stop information so that the symbol stops on the active line.

  As a result, when all the small roles are won but the first replay is not won, the left stop switch 42 is operated when the symbols other than No. 16 on the left reel 32L reach the lower stage. In such a case, a fourth small winning combination is established on one of the first line L1 and the fourth line L4, and a seventh small winning combination is established on the other. If the left stop switch 42 is operated while the 16th symbol of the left reel 32L has reached the lower level, the 17th “white 7” symbol stops at the lower level while the “bell” symbol is the upper level. Without stopping, only the seventh small role winning is established. In the CB state A, when all the small roles are won, but the first replay is not won, the forward stop operation is performed and the left stop switch 42 is aimed at the “BAR” symbol of the left reel 32L. Is operated on the auxiliary display unit 65. Therefore, the player can establish the fourth small winning combination and the seventh small winning combination by operating the stop switches 42 to 44 by the notified operation method, and can pay out 3 (= 2 + 1) medals. Can receive.

  When all the small roles and the first regame are won, stop information is set in the stop information setting process so that the “replay” symbol as the first replay symbol stops on the active line.

  In the middle reel 32M and the right reel 32R, a “replay” symbol as the first replay symbol is arranged so that the interval between the symbols of the same kind is 4 symbols or less. Even in the CB state, the middle reel 32M and the right reel 32R can be stopped after sliding a maximum of four symbols. Therefore, in the stop information setting process, when all the small roles and the first replay are won, the “replay” symbol as the first replay symbol is displayed regardless of the operation timing of the middle stop switch 43 and the right stop switch 44. Set stop information to stop on the active line.

  Similar to the middle reel 32M and the right reel 32R, the left reel 32L is provided with a “replay” symbol as the first replay symbol so that the interval between the same symbols becomes four symbols or less. Here, in the CB state, since the maximum number of slips of the left reel 32L changes to one symbol, the “replay” symbol cannot be stopped at an arbitrary position. For example, if the left stop switch 42 is operated while the number 10 “replay” symbol of the left reel 32L has reached the middle level, the “replay” symbol can only be stopped at the middle level or the lower level. However, in the CB state, effective lines are set in the upper and lower stages of the left reel 32L, that is, effective lines are set after one symbol separation, so if the interval between “replay” symbols is three or less symbols The “replay” symbol can be stopped on the active line. On the left reel 32L, except for the 14th to 19th sections, the “replay” symbols are arranged so that the interval between them becomes 3 symbols. Therefore, in the stop information setting process, when all the small roles and the first replay are won, the case where the left stop switch 42 is operated when the 15th “bell” symbol has reached the lower stage. Except for this, stop information is set so that the “replay” symbol as the first replay symbol stops on the active line. If the left stop switch 42 is operated while the 15th “bell” symbol has reached the lower stage, the “replay” symbol cannot be stopped on the active line. Stop information is set so that a winning corresponding to the fourth small combination and the seventh small combination that is the winning combination is established.

  When the left stop switch 42 is first operated and the operation timing is the timing when the “Bell” symbol of No. 15 reaches the lower stage, there is no room for the first re-game winning, There remains room for winning the fourth small part winning and the seventh small part winning. In such a case, in the stop information second setting process, stop information is set so that the “replay” symbols as the fourth small role symbol and the seventh small role symbol stop on the active line regardless of the operation timing of the middle stop switch 43. In addition to the change, the stop information is changed so that the “bell” symbol as the fourth small role symbol and the seventh small role symbol stops on the active line regardless of the operation timing of the right stop switch 44.

  As a result of the above, when all the small roles and the first replay are won, the left stop switch 42 is operated first, and the operation timing is the timing when symbols other than No. 15 reach the lower stage. If this is the case, the first re-game winning prize is established on the first line L1 or the fourth line L4. When the left stop switch 42 is operated first and the operation timing is the timing when the symbol No. 15 reaches the lower stage, the fifth small part winning is established in the first line L1 and the fourth A fourth small winning combination is established at line L4. In the CB state A, when all the small roles and the first replay are won, the auxiliary display unit 65 notifies that the forward pressing operation is performed. Therefore, the player can establish the first re-game winning or the fourth small winning and the seventh small winning by operating the stop switches 42 to 44 by the notified operation method.

  FIG. 21 is a diagram illustrating a correspondence relationship between a symbol that has reached the lower stage when the left stop switch 42 is operated in the CB state B and a stop mode (slip number) of the left reel 32L.

  If all the small combinations are won, but the second replay and the third replay are not won, the stop information setting process and the stop information second setting process may increase the number of small combinations that will win a prize. Set stop information in. That is, the same stop information as in the CB state A is set. In the CB state B, when all the small roles are won, but the second replay and the third replay are not won, as in the CB state A, the forward push operation is performed, and the left reel 32L Operation of the left stop switch 42 aiming at the “BAR” symbol is notified in the auxiliary display unit 65. Therefore, the player can establish the fourth small winning combination and the seventh small winning combination by operating the stop switches 42 to 44 by the notified operation method, and can pay out 3 (= 2 + 1) medals. Can receive.

  When all the small roles, the second regame, and the third regame are won, stop information is set in the stop information setting process so that the second regame symbol stops on the active line.

  On the middle reel 32M and the right reel 32R, a “bell” symbol which is a second replay symbol is arranged so that the interval between the symbols of the same kind is 4 symbols or less. Even in the CB state, the middle reel 32M and the right reel 32R can be stopped after sliding a maximum of four symbols. Therefore, in the stop information setting process, when all the small roles, the second regame, and the third regame are won, the second regame symbol is used regardless of the operation timing of the middle stop switch 43 and the right stop switch 44. Stop information is set so that the “bell” symbol stops on the active line.

  On the left reel 32L, only one “youth” symbol, which is the second replay symbol, is arranged at the 16th position. Since the maximum number of slips of the left reel 32L in the CB state is one symbol, in the CB state, when the left stop switch 42 is operated when the symbols No. 13 to No. 16 of the left reel 32L reach the lower stage. Only, the “youth” symbol which is the second replay symbol can be stopped on the active line. Further, on the left reel 32L, “replay” symbols as third replay symbols are arranged at positions 14 and 19. The 14th “Replay” design and the 16th “Youth” design are separated by 1 design, and the 16th “Youth” design and the 19th “Replay” design are separated by 2 designs. In addition, as described above, the left reel 32L is arranged so that the interval between the “replay” symbols is 3 symbols, except for the 14th to 19th sections. Therefore, in the stop information setting process, if all the small roles, the second regame, and the third regame are won, the second replay symbol can be stopped if it can be stopped on the active line. If it is impossible to stop the second replay symbol on the active line so that the replay symbol stops on the active line, the stop information is set so that the third replay symbol stops on the active line. Set.

  When the left stop switch 42 is operated for the first time in the situation where all the small roles, the second replay and the third regame are selected, the operation timing of the symbols 13 to 16 reaches the lower stage. At the same timing, there remains room for the second regame prize to be established, while at other timings, there is room for the third regame prize to be established instead of the second regame prize. If there is still room for a third re-game prize to be established instead of the second re-game prize, in the stop information second setting process, the middle reel 32M and the right reel so that the third re-game symbol stops on the active line. 32R stop information is changed. On the middle reel 32M, “replay” symbols as third replay symbols are arranged at intervals of 4 symbols or less. On the other hand, the right reel 32R is provided with a section (specifically, a section from No. 15 to No. 0) in which the “white 7” symbol as the third replay symbol is separated by 5 symbols. In the CB state, an effective line is set only at the upper stage of the right reel 32R. Therefore, when the right stop switch 44 is operated when the 14th symbol of the right reel 32R has reached the lower stage, the right reel 32R. Even if it is stopped after sliding for 4 symbols, the “white 7” symbol cannot be stopped on the active line. In other words, when the left stop switch 42 is first operated in the situation where all the small roles, the second replay and the third replay are won, the operation timing of the left stop switch 42 and the right stop switch 44 Missing can occur.

  When the middle stop switch 43 and the right stop switch 44 are operated before the left stop switch 42 in the situation where all the small roles, the second replay and the third replay are elected, the operation timing is set. Regardless, the “bell” symbol as the second replay symbol stops on the active line. Here, the “bell” symbol of the middle reel 32M has the function as the third small role symbol in addition to the function as the second replay symbol, and the “bell” symbol of the right reel 32R is the second symbol. In addition to the function as a replay symbol, it has a function as a third small role symbol to a seventh small role symbol. Then, as shown in FIG. 22A, when the “bell” symbols of the middle reel 32M and the right reel 32R are stopped on the active line, the third small prize winning is established in addition to the second regame winning. There remains room. Therefore, in the stop information second setting process, if all the small roles, the second regame, and the third regame are won, if the second regame symbol can be stopped on the active line, Stop so that the second small game symbol stops on the active line if it is impossible to stop the second regame symbol on the active line so that the second replay symbol stops on the active line Set the information.

  As a result, when all the small roles, the second replay and the third replay are won, the middle stop switch 43 and the right stop switch 44 are operated before the left stop switch 42, When the left stop switch 42 is operated at the timing when the symbols No. 13 to No. 16 of the left reel 32L reach the lower stage, for example, the stop appearance as shown in FIG. 22 (b) occurs, and the first line L1 or A second regame prize is established on the fourth line L4. The middle stop switch 43 and the right stop switch 44 are operated before the left stop switch 42, and at the timing when the symbols of No. 0 to No. 12 and No. 17 to No. 20 of the left reel 32L reach the lower stage When the stop switch 42 is operated, for example, the stop turn shown in FIG. 22C is made, and the third small winning combination is established in the first line L1 or the fourth line L4.

  In the CB state B, when all the small roles, the second regame, and the third regame are won, the reverse push operation can be performed when all the reels 32L, 32M, and 32R start to rotate. Notification is made in the auxiliary display unit 65. When the middle reel 32M and the right reel 32R are stopped and only the left reel 32L is rotating, the left stop switch 42 can be operated aiming at the “BAR” symbol of the left reel 32L. Notification is made in the auxiliary display unit 65. Therefore, the player can receive the 15 medals by establishing the third small part winning by operating the stop switches 42 to 44 by the notified operation method.

  Next, the number of medals that can be acquired by the player in the CB state will be described.

  In the CB state A, either a winning situation where all the small roles are won or a winning situation where all the small roles and the first replay are won occur. The probability of winning the winning status for all the small roles is about 1 / 1.2, and the probability of winning the winning status for all the small roles and the first replay is about 7.3 minutes. 1 of When the winning situation is that all the small roles have been won, the player operates the stop switches 42 to 44 by the notified operation method to establish the fourth small role winning and the seventh small role winning. 3 (= 2 + 1) medals can be received. When the winning situation is that all the small roles and the first replay are won, the player operates the stop switches 42 to 44 by the informed operation method, so that the first replay winning prize or the first replay The 4th small role winning and the 7th small role winning can be established. That is, when the player shifts to the CB state A, the player can receive a replay privilege or a medal payout privilege. Since the CB state A ends when the number of paid-out medals reaches 268, when the CB state A is entered, at least 90 games must be played in order to end the CB state A. In the CB state A, two medals are bet and one game is played, so the player needs to bet 180 (= 2 × 90) medals before the CB state A ends. Since 270 (= 3 × 90) medals are paid out until the CB state A ends, when the player moves to the CB state A, the player can expect an increase of about 90 owned medals.

  In the CB state B, one of a winning situation where all the small roles are won and a winning situation where all the small roles, the second replay and the third regame are won occur. The probability of winning the winning status for all the small roles is about one-third, and the probability of winning the winning status for all the small roles, the second replay and the third replay is It is about 1 / 1.4. When the winning situation is that all the small roles have been won, the player operates the stop switches 42 to 44 by the notified operation method to establish the fourth small role winning and the seventh small role winning. 3 (= 2 + 1) medals can be received. When the winning situation in which all the small roles, the second regame, and the third regame are won, the player operates the stop switches 42 to 44 by the informed operation method to thereby execute the third small game. A winning prize can be established. That is, when the player shifts to the CB state B, the player can receive a privilege of paying out 3 or 15 medals. Since the CB state A ends when the number of paid-out medals reaches 268, when shifting to the CB state B, it is necessary to play an average of 24 games in order to end the CB state B. In CB state B, two medals are bet and one game is played, so the player needs to bet 48 (= 2 × 24) medals before CB state B ends. Since it can be expected that about 274 medals will be paid out before the CB state B ends, when the player moves to the CB state B, the player can expect to increase the number of owned medals by about 226.

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

  If the first CB or the second CB is won in the normal gaming state, the CB state A is transferred after the CB winning is established. If the first CB or the second CB is won in the RT state, the CB state B is entered after the CB winning is established. The configuration is to be migrated. In the CB state A, the winning probability of the first replay in the normal gaming state is taken over, and in the CB state B, the winning probabilities of the second replay and the third replay are taken over. By adopting such a structure, when the player wins the first CB or the second CB under the RT state, the player has the impression that the player has lost the profit that he has obtained under the RT state. It is possible to suppress the deterioration of the.

  In the case of winning all the small roles, the second replay, and the third replay in the CB state, the player operates the stop switches 42 to 44 by the informed operation method, so that in the second replay prize The third small role winning can be established and 15 medals can be paid out. With this configuration, when winning the first CB or the second CB in the RT state, it is possible to allow the player to acquire more medals than when winning the first CB or the second CB in the normal gaming state. Become.

  When all the small roles, the second regame, and the third regame are won in the CB state, the third small role winning is established by operating the stop switches 42 to 44 by the operation method notified by the player. The configuration can be made. With such a configuration, it becomes possible for the player to actively participate in the game, and it is possible to suppress the game in the CB state from becoming monotonous. Certainly, the symbol arrangement of each of the reels 32L, 32M, and 32R and the reel stop control can be set so that the third small winning combination is established regardless of the operation timing and operation sequence of the stop switches 42 to 44. . However, when such a configuration is adopted, an act such as aiming at a symbol becomes unnecessary, and a game under the CB state may be monotonized.

  When the “bell” symbol of each reel 32L, 32M, 32R stops on the active line, the third small role winning is established, the “young” symbol of the left reel 32L, the “reel” symbol of the middle reel 32M and the right reel 32R. When the “bell” symbol stops on the active line, the second re-game winning prize is established. In this way, the “bell” symbol of the middle reel 32M and the right reel 32R has the function as the third small role symbol and the function as the second replay symbol, so that the middle reel 32M and the right reel 32R. When at least one of these is stopped before the left reel 32L, it is possible to leave both the room for the second re-game winning and the room for the third small winning combination. As a result, when all the small roles, the second regame and the third regame are won in the CB state, the frequency of occurrence of an event in which neither the second regame prize nor the third small role prize is established is reduced. It becomes possible to make it.

  When all the small roles, the second replay, and the third replay are won in the CB state, the middle stop switch 43 and the right stop switch 44 are operated before the left stop switch 42, and the left reel 32L 13 When the left stop switch 42 is operated at the timing when the symbols No. 16 to No. 16 reach the lower stage, the second re-game is won, and the middle stop switch 43 and the right stop switch 44 are operated before the left stop switch 42. At the same time, when the left stop switch 42 is operated at the timing when the symbols of No. 0 to No. 12 and No. 17 to No. 20 of the left reel 32L reach the lower stage, the third small winning combination is established. In this way, the symbol arrangement of the left reel 32L is configured such that the section in which the third small prize winning can be established is longer than the section in which the second re-game winning can be established. This makes it possible to increase the possibility that the third small role winning will be established.

  Since the configuration shifts to the RT state after the CB state ends, if the first CB or the second CB is won in the RT state, it becomes possible to play the game in the RT state again after the CB state ends. . As a result, when the first CB or the second CB is won in the RT state, it is possible to suppress the player from having an impression that the player has lost the profit that the player can obtain in the RT state.

  When the value of the remaining game number counter becomes 0 in the CB state, that is, when the sum of the number of games in the RT state and the number of games in the CB state reaches 100, the RT setting flag is cleared. The RT state processing is terminated as it is. By adopting such a configuration, it is possible to avoid changes in the winning probabilities of the second replay and the third replay under the CB state, and to suppress the player from diminishing the willingness to play. Is possible. Certainly, the RT setting flag may be cleared when the value of the remaining game number counter becomes 0 in the CB state. However, in such a configuration, for example, when the first CB or the second CB is won in the 99th game in the RT state, only the first game in the CB state becomes a game in the CB state B, and the other games are CB It becomes a game in state A. This is because the player may be discouraged for not having won the first CB or the second CB in the number of games with a small RT state, which may reduce the willingness to continue the game after the end of the CB state. . On the other hand, in the above embodiment in which the RT setting flag is not cleared when the value of the remaining game number counter becomes 0 in the CB state, the above-mentioned concern can be avoided.

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

  (1) In the above-described embodiment, the configuration shifts to the RT state after the end of the CB state. However, instead of or in addition to this, the configuration may shift to the RT state when other transition conditions are satisfied. . Other transition conditions include, for example, that a predetermined number of games (for example, 1200 times) are performed in the normal gaming state, a predetermined combination of symbols stopped on the active line, etc. Take as an example.

  (2) In the above embodiment, the RT state is terminated when 100 games are played in the RT state. Instead, the RT state is terminated when a predetermined combination is won. Alternatively, the RT state may be terminated when a predetermined winning is achieved.

  (3) In the above embodiment, the CB state is terminated when the number of medals paid out reaches 268. However, the number of medals paid out as an end condition for the CB state is arbitrary. Further, the CB state may end when a predetermined winning combination is won, or the CB state may end when a predetermined winning is achieved.

  (4) In the embodiment described above, the stop mode of the left reel 32L changes when the state shifts to the CB state. However, the stop mode of the middle reel 32M may be changed, or the right reel 32R may stop. It is good also as a structure from which an aspect changes. Moreover, it is good also as a structure from which the stop mode of two or more reels changes instead of the stop mode of one reel.

  (5) In the above embodiment, the configuration is such that the number of bets and the active line required for one game change when the game moves to the CB state, but at least one of them may not change.

  (6) In the above embodiment, the second replay and the third replay are not won in the normal game state and the CB state A. However, the second replay has a lower probability than the RT state and the CB state B. And it is good also as a structure won by 3rd regame.

  (7) In the above embodiment, in the CB state, it is configured to determine whether or not the winning combination is succeeded by the role type that gives the re-playing privilege in the gaming state when winning the first CB or the second CB and the winning probability. However, it is not limited to such a configuration. If the winning probability of the second replay and the third regame in the CB state A is lower than the winning probability of the second replay and the third regame in the CB state B, a replay privilege is granted. Even if it is a configuration in which at least one of the role to be played and the winning probability thereof is changed, it can be expected that the same operational effects as those of the above-described embodiment are achieved.

  (8) In the above embodiment, in the RT state and the CB state B, both the second regame and the third regame are won. However, only the third regame is selected. Even if it exists, there can exist an effect similar to the said embodiment. However, in the case of such a configuration, the frequency of missing is increased when the third replay is won in the RT state.

  (9) In the above-described embodiment, the combination of symbols for winning a prize is an example, and is not limited to the combination of symbols. In addition, the number of symbol combinations for winning a prize is also arbitrary.

  (10) In the above embodiment, the slot machine having the CB state has been described. However, the present invention is not limited to such a configuration, and may be a slot machine having the BB state, or may be an RB state or an SB state. It may be a slot machine having other gaming states such as a CT state.

  (11) In the above embodiment, as a privilege to be granted, a privilege including a medal is paid out in addition to the privilege that the gaming state shifts and the privilege of replaying, but the configuration is limited to this configuration. Instead, any configuration may be used as long as the player is given some kind of privilege. 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.

  (12) In the above embodiment, a slot machine having three reels arranged in parallel and having four 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. It may be a slot machine provided or a slot machine having seven effective lines.

  (13) In the above embodiment, an example in which the slot machine 10 is embodied has been shown. However, the present invention may be applied to a gaming machine of a type in which a slot machine and a pachinko machine are fused. 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 where pachinko machines and slot machines are mixed 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.

  Hereinafter, the gaming machine of the present invention will be described while showing effects and the like as necessary. In the following, for ease of understanding, the corresponding configuration in the above embodiment is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.
