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, A lottery such as a re-game is performed and each reel starts to rotate. After each reel starts rotating, 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 which shifts when a BB winning is established, for example, a replay time (hereinafter referred to as “RT”) in which the probability of winning a replay is higher than the normal gaming state. There is something with a state. Further, in recent years, after the BB state is finished, when a predetermined period such as a so-called chance zone is entered and a predetermined winning can be established during the predetermined period, the gaming state shifts to the RT state, and the predetermined winning is achieved. There has also been proposed a slot machine in which the gaming state does not shift to the RT state when it cannot be established (see, for example, Patent Document 1).

  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 applying 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), “young man” symbol (for example, 19th of left reel 32L), “cherry” symbol (for example, 18th of left reel 32L), “ “Replay” symbol (eg, 16th of left reel 32L), “Blue 7” symbol (eg, 14th of left reel 32L), “Watermelon” symbol (eg, eleventh of left reel 32L), “BAR” symbol ( For example, there are 8 types of “red 7” symbols (e.g., second of the left reel 32L). As shown in FIG. 6, the number and arrangement order of various symbols on the reels 32L, 32M, and 32R are completely different.

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

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

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

  There are Bell prize and Cherry prize as small prizes where medals are paid out. When the “bell” symbol of each reel 32L, 32M, 32R stops on the active line, 12 medals are paid out as a bell winning. When the “cherry” symbol on the left reel 32L stops on the active line, two medals are paid out as a cherry prize. That is, in the case of a cherry winning, any symbol may be stopped on the active line for the middle reel 32M and the right reel 32R. In other words, if the combination of the “cherry” symbol of the left reel 32L and any symbol of the middle reel 32M and the right reel 32R stops on the active line, it can be said that a cherry prize is established. Therefore, when the “cherry” symbol stops at the position where the plurality of effective lines of the left reel 32L overlap (specifically, the upper stage and the lower stage), a corresponding cherry winning is established on each effective line. .

  As a state transition prize in which a game state transition is performed, there is a BB prize.

  When the “red 7” symbol of each reel 32L, 32M, 32R stops on the effective line and when the “blue 7” symbol of each reel 32L, 32M, 32R stops on the effective line, BB Winning a prize. When the BB winning is established, the gaming state shifts to the BB state.

  There are a first re-game prize and a second re-game prize as prizes to which a re-game privilege that can be played in the next game 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 winning prize, and the “bell” symbol of the left reel 32L, the “replay” of the middle reel 32M and the right reel 32R. When the symbol stops on the active line, the second replay prize is awarded.

  In the following, a combination of symbols corresponding to each prize is also referred to as a combination of winning symbols. For example, the combination of the second replay symbol is a combination of symbols for the second replay winning, that is, a combination of a “bell” symbol, a “replay” symbol, and a “replay” symbol. The symbols of the reels 32L, 32M, and 32R corresponding to the winnings are also referred to as winning symbols. For example, the second replay symbol is a “bell” symbol in the left reel 32L, and a “replay” symbol in the middle reel 32M and 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.

It has become.

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

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

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

  On the output side of the main controller 101, a reel unit 31 (more specifically, a stepping motor for rotating the reels 32L, 32M, and 32R), a medal path switching solenoid 46a provided in the selector 46, a hopper device 51, a credit A display unit 60, a payout number display unit 62, a display control device 81, an external concentration terminal board 121 capable of transmitting information to a hall management device (not shown), and the like are connected via an input / output port 104.

  The display control device 81 is a control device for driving the upper lamp 63, the speaker 64, and the auxiliary display unit 65, and includes a substrate on which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving a signal from the main controller 101, the display controller 81 independently controls the upper lamp 63, the speaker 64, and the auxiliary display unit 65. Therefore, the display control device 81 is a sub-base for executing auxiliary control in relation to the main control device 101 which is a main base for overall management of games. The various display units 60 and 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 21 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 BB status, etc., a backup area is provided.

  The backup area is an area for storing the value of the stack pointer when the power is shut down due to the occurrence of a power failure or the like (including power shutdown by operating the power switch 71; the same applies hereinafter). Yes, when the power failure is resolved (including power-on by operating the power switch 71; the same applies hereinafter), the state of the slot machine 10 can be restored to the state before power-off based on the backup area information. . Writing to the backup area is executed when the power is 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 among these processes, 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 the segment data displayed on the credit display unit 60 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 and 62 to display the corresponding numbers and symbols. 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 the first regame prize or the second regame prize 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 a specified number (3 in the present embodiment). If the bet number has not reached the specified number, step S204 is performed. Returning to the start waiting process, the process after the sensor abnormality confirmation process is performed. If the bet number has reached the specified number, it is determined in step S206 whether or not the start lever 41 has been operated. When the start lever 41 is not operated, the process returns to the start waiting process of step S204, and the processes after the sensor abnormality confirmation process are performed among the processes.

  On the other hand, when the start lever 41 is operated, the game can be started when the start lever 41 is operated in a situation where a prescribed number of medals are betted. Means that a command has occurred. In such a case, the process proceeds to step S207, and an effective line setting process for setting all the combination lines L1 to L5 described above as effective lines is performed, and a start command is set. Here, the start command is a command transmitted to the display control device 81 in order to grasp that a start command has been generated. However, in the normal process, various commands such as the start command are only set in the ring buffer, and the command is not transmitted to the display control device 81. The command transmission to the display control device 81 is performed in the command output process S110 of the timer interrupt process described above. In 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 BB 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. The slot machine 10 is roughly divided into four types of game states: a normal game state, a preparation state, an RT state, and a BB state. 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, if the determination value DV exceeds 65535 when IV = 3, in step S306, a bell winning flag is set in the winning flag storage area 106a.

  Incidentally, when the set winning flag is not the BB winning flag, 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 BB winning flag, the BB winning flag is reset as one of the conditions that the BB winning is established. That is, the BB winning flag may be valid for a plurality of games.

  If the determination value DV does not exceed 65535 in step S305, it means that the combination corresponding to the index value IV is lost. In such a case, 1 is added to the index value IV in step S307, and in the subsequent step S308, it is determined whether or not there is a combination corresponding to the index value IV, that is, whether or not there is a determination target to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index values IV set in the lottery table. If there is a determination target to be determined whether or not, the process returns to step S304 and the determination of whether or not the winning combination is continued. At this time, in step S304, a point value PV corresponding to the current index value IV is added to the determination value DV (that is, the current determination value DV) used for determining whether or not the previous winning combination is a new determination value DV. In step S305, whether or not a winning combination is made is determined based on the determination value DV.

  Incidentally, when the winning combination determination is performed using the lottery table shown in FIG. 13, the winning probability of the first replay is about 7.36 and the winning probability of the second replay is about 840. The winning probability of Bell is about 6.00, the winning probability of Cherry is about 12.0, and the winning probability of BB is about 1/990. The probability of losing none of the roles is about 1.63.

  After the winning flag is set in step S306, or when it is determined in step S308 that there is no determination target to be determined, it means that the winning combination determination has ended. In such a case, a lottery result command is set in step S309. Here, the lottery result command is a command that is transmitted to the display control device 81 in order to grasp the result of the combination determination.

  In step S310, stop information setting processing for setting stop information for reel stop control is performed, and the lottery processing is terminated. In the stop information setting process, stop information of each reel 32L, 32M, 32R is set so that the winning symbol corresponding to the winning flag can be stopped on the active line. At this time, when the BB winning flag and other winning flags are set, stop information is set as follows. When the other winning flag is the first re-game winning flag or the second re-game winning flag, each reel 32L, 32M, so that the winning re-playing symbol has priority over the BB symbol and stops on the active line. 32R stop information is set. Further, when the other winning flag is a small character winning flag such as a watermelon winning flag, each of the reels 32L, 32M, and 32R is stopped so that the winning small character symbol has priority over the BB symbol and stops on the active line. Set stop information.

  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 reaches a constant speed, the CPU 102 can generate a stop command by lighting up a lamp (not shown) of each stop switch 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.

  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 the first re-game winning or the second re-game winning is achieved. If none of the re-game winnings have been established, the medal payout process is terminated, and if any of the re-game winnings have been established, a re-game setting process is performed for changing the gaming state to the re-gaming state. 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. Further, when the count value of the credit counter reaches the upper limit, or when the count value reaches the upper limit during the addition of the payout number, the medal payout rotating plate is driven and the medal is discharged from the hopper device 51. It pays out to the medal tray 50 through the exit 49. In the medal payout process, a process of changing the payout number displayed on the payout number display unit 62 in accordance with the medal payout is also performed. Further, when the current gaming state is the BB state, a process of subtracting the payout number from the value of the remaining payout number counter described later is performed.

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

  Prior to the description of the BB state process, the BB state will be described. The BB state is composed of a plurality of RB states. The RB state consists of 12 JAC games. A JAC game is a game in which the probability of winning a prize is very high compared to a normal state. If the winning is established 8 times during the JAC game, the RB state is ended even before the JAC game is played 12 times. Further, the BB state ends when the number of medals paid out reaches a predetermined number (specifically, 365). In addition, when the medal payout number reaches a predetermined number in the middle of the RB state, not only the BB state but also the RB state ends. Further, the slot machine 10 does not set a combination of symbols to be shifted to the RB state, and is configured to shift to the RB state immediately after shifting to the BB state and immediately after the end of the RB state. Therefore, it can be said that the BB state is a game that continuously shifts to the RB state until a predetermined number of medals are paid out.

  In the BB state process, first, in step S501, it is determined whether or not the current gaming state is the BB state. If not in the BB state, BB determination processing shown in steps S502 to S505 is performed.

  In the BB determination process, it is determined whether or not a BB winning flag is set in step S502. If the BB winning flag is set, the process proceeds to step S503, and it is determined whether or not a BB winning is achieved based on the winning combination set in the previous payout determination process. If a BB winning is established, a BB start process is executed in step S504 to shift the gaming state to the BB state. Specifically, the BB winning flag is cleared and the BB setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the BB state. In addition, 365 is set in a remaining payout counter for counting the number of remaining medals that can be paid out during the BB state provided in the state information storage area 106c. When a first preparation setting flag, which will be described later, is set in the state information storage area 106c, the BB setting flag is set after clearing the setting flag. In subsequent step S505, an RB start process is performed. In the RB start process, the RB setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the RB state. Further, 8 is set in the remaining winning number counter for counting the number of winnings established in the RB state, and 12 is set in the remaining JAC game counter for counting the remaining number of games in the JAC game. The remaining winning number counter and the remaining JAC winning counter are provided in the state information storage area 106c. When the RB start process is finished, a status command is set in step S506, and this process is finished. 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 S506, 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. For example, when the BB setting flag is set in the status information storage area 106c, a status command indicating the BB status is set.

  If the BB setting flag is set in step S504, the gaming state shifts to the BB state. In step S302 of the lottery process, it is determined that the current gaming state is the BB state based on the BB setting flag being set in the state information storage area 106c, and the lottery table for the BB state is selected.

  FIG. 16 is a lottery table for the BB state selected in the BB state of “Setting 3”. In the BB state lottery table, the same five determination objects as the normal game state lottery table are set, but different points for each index value IV won in the first replay, bell, and BB. The value PV is set. If the winning combination is determined using the lottery table, the winning probability of the first replay is about 1/600, the winning probability of the second replay is about 1/840, The winning probability is about 1.50, the cherry winning probability is about 12.0, and the BB winning probability is 0. The probability of losing no winning combination is about one-twelfth.

  Returning to the description of the BB state process, when the BB winning flag is not set (when Step S502 is NO), or when the BB winning is not established (when Step S503 is NO), the BB start process, etc. In step S506, the status command is set without executing the process, and the process is terminated.

  If it is determined in step S501 that the current gaming state is the BB state, a BB end determination process shown in steps S507 to S517 is executed. In the BB end determination process, first, in step S507, it is determined whether or not a winning is achieved based on the winning combination set set in the previous payout determination process. If a win is established, the value of the remaining prize counter is decremented by 1 in step S508. Thereafter, or when it is determined in step S507 that no winning has been established, one JAC game has been consumed, and thus the value of the remaining JAC game counter is decremented by 1 in step S509. Subsequently, in step S510, it is determined whether either the remaining prize counter or the remaining JAC game counter has become zero. If any of them is 0, that is, if the winning is achieved 8 times or the JAC game is consumed 12 times, it means that the RB state end condition is satisfied, so in step S511, the remaining winning number counter And the RB end processing for clearing the value of the remaining JAC game counter is performed. In subsequent step S512, it is confirmed whether or not the count 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 BB state has not reached the predetermined number and the end condition for the BB state is not satisfied, so the process proceeds to step S513, where the RB start described above is started. Process. Thereafter, a status command is set in step S506, and this process ends.

  If neither the value of the remaining winning counter or the remaining JAC game counter is 0 in step S510, that is, if the winning has not been established 8 times and the JAC game has not been consumed 12 times, the process proceeds to step S514. Then, it is confirmed whether or not the count 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 BB state has not reached the predetermined number and the end condition for the BB state is not satisfied, so a state command is set in step S506. This process is terminated. On the other hand, when the count value of the remaining payout number counter is 0, it means that the BB state end condition is satisfied, so the BB state end process shown in steps S515 to S516 is performed. In the BB state end process, first, in step S515, the above-described RB end process is performed. Thereafter, in step S516, a BB end process for appropriately clearing the BB setting flag and various counters is performed. In addition, when the count value of the remaining payout number counter is 0 in step S512, it means that the BB state end condition is satisfied, so the BB end process is performed in step S516. When the BB end process is performed, the first preparation start process is executed to shift the gaming state to the first preparation state in step S517, and the BB state process is ended. In the first preparation start process, the first preparation setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the first preparation state. Further, 3 is set in the remaining game number counter for counting the number of remaining games provided in the state information storage area 106c.

  By the way, in the BB state of “setting 3”, when the first replay and the second replay are regarded as a combination in which three medals are paid out when the winning is established, the expected value of the medals paid out per game is about 8 It can be expected that there will be about 5.8 medals per game. However, the medals that are actually paid out at the time of winning the prize are Bell and Cherry, and when the first re-game winning or the second re-game winning is established, the number of pay-outs is not set in the pay-out information storage area (that is, Therefore, the value of the remaining payout number counter is not subtracted. When the first replay and the second replay are not taken into consideration, the expected value for paying out medals per game is about 8.3. Since the BB state ends when the number of medals paid out reaches 365, it can be expected that about 44 games will be played in the BB state.

  As described above, in the slot machine 10, when the BB state is finished, the gaming state is shifted to the first preparation state. In step S302 of the lottery process, it is determined that the current gaming state is the preparation state based on the first preparation setting flag being set in the state information storage area 106c, and the preparation state lottery table is selected. .

  FIG. 17 is a preparation state lottery table selected in the “setting 3” preparation state. In the preparation state lottery table, the same five determination targets as the normal game state lottery table are set, while the index value IV which is won in the first replay and the index which is won in the second regame. Different point values PV are set for the value IV. If the winning combination is determined using the lottery table, the winning probability of the first replay is about 1 / 6.0, and the winning probability of the second replay is about 1 / 2.00. The winning probability of Bell is about 6.00, the winning probability of Cherry is about 12.0, and the winning probability of BB is about 1/990. The probability of losing no winning combination is about one-twelfth. In the first preparation state of “setting 3”, when the first replay and the second replay are regarded as a combination in which three medals are paid out when winning is established, the expected value of medals paid out per game is about 4 It can be expected that the number of medals will increase to about 1.3 per game.

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

  In step S601, it is determined whether or not the current gaming state is the first preparation state. If the current gaming state is the first preparation state, the first transition determination process is performed in step S602, and then this process ends.

  In the first transition determination process, as shown in the flowchart of FIG. 19, in step S701, it is determined whether or not a Bell winning combination has been established based on the winning combination set in the previous payout determining process. When the bell winning is established, the process proceeds to step S702, and after the RT start process is performed, this process is terminated. In the RT start process, the first preparation setting flag set in the state information storage area 106c is cleared and the RT setting flag is set in the state information storage area 106c to set the gaming state to the RT state. Also, 100 is set in the remaining game number counter. If it is determined in step S701 that the bell winning is not established, the process proceeds to step S703, and it is determined whether or not the first re-game winning is established based on the winning combination set in the previous payout determining process. judge. If the first re-game winning is established, the normal game start process is performed in step S704, and then this process is terminated. In the normal game start process, the first preparation setting flag set in the state information storage area 106c is cleared, and the game state is changed to the normal game state. If it is determined in step S703 that the first regame prize has not been established, the process proceeds to step S705, where the second regame prize is established based on the winning combination set in the previous payout determination process. Determine whether or not. When the second regame winning is established, the second preparation start process is performed in step S706, and then the present process is terminated. In the second preparation start process, the first preparation setting flag set in the state information storage area 106c is cleared, the second preparation setting flag is set in the state information storage area 106c, and the gaming state is set to the second preparation state. And Also, 3 is set in the remaining game number counter. If it is determined in step S705 that the second replay prize has not been established, the value of the remaining game number counter is decremented by 1 in step S707, and the remaining game number counter value is 0 in step S708. It is determined whether or not. If the value of the remaining game number counter is not 0, the process is terminated as it is. If the value of the remaining game number counter is 0, the process is performed after the third preparation start process is performed in step S709. finish. In the third preparation start process, the first preparation setting flag set in the state information storage area 106c is cleared, the third preparation setting flag is set in the state information storage area 106c, and the gaming state is changed to the third preparation state. And Also, 3 is set in the remaining game number counter.

  As described above, in the first preparation state, when the bell winning, the first re-game winning, or the second re-game winning is achieved, the game is performed three times without any of the winnings. Exit if In the first preparation state, when the bell winning is established, the gaming state is shifted to the normal gaming state, and when the first re-game winning is established, the gaming state is shifted to the RT state. When the gaming state shifts to the RT state, the RT state lottery table is selected in step S302 of the lottery process.

  FIG. 22 is an RT state lottery table selected in the RT state of “Setting 3”. In the RT state lottery table, the same five determination targets as the normal game state lottery table are set, but different point values PV are set for each index value IV that is won in the first replay. Has been. If the winning combination is determined using the lottery table, the winning probability of the first replay is about 1.50 and the winning probability of the second regame is about 1/840. The winning probability is about 6.00, the cherry winning probability is about 12.0, and the BB winning probability is about 990. The probability of losing no winning combination is about 12.3. In the “setting 3” RT state, when the first replay and the second replay are regarded as a combination where three medals are paid out, the expected value of medals paid out per game is about 4.3, It can be expected that approximately 1.3 medals will increase per game. By the way, in the normal game state of “Setting 3”, when the first replay and the second replay are regarded as a combination where three medals are paid out, the expected value of medals paid out per game is about 2.7. It can be expected that there will be about 0.3 medals per game. In other words, the player can play a game in an advantageous situation when the player transitions to the RT state as compared to the case where the player transitions to the normal gaming state.

  Further, in the first preparation state, when the second re-game winning is established, the gaming state shifts to the second preparation state, and when the game is performed three times under the first preparation state, the gaming state is the first 3. Move to the ready state. When the gaming state shifts to the second preparation state or the third preparation state, the preparation state lottery table is selected in step S302 of the lottery process. That is, in the second preparation state and the third preparation state, the winning probability of each combination is equal to the first preparation state.

  Returning to the description of the RT state process, if it is determined in step S601 that the current gaming state is not the first preparation state, it is determined in step S603 whether or not the current gaming state is the second preparation state. . If the current gaming state is the second preparation state, the second transition determination process is performed in step S604, and then the present process ends.

  In the second transition determination process, as shown in the flowchart of FIG. 20, the value of the remaining game number counter is decremented by 1 in step S801, and whether or not the value of the remaining game number counter is 0 in step S802. judge. If the value of the remaining game number counter is not 0, the process is terminated. If the value of the remaining game number counter is 0, the process is performed after the first preparation start process is performed in step S803. finish. In the first preparation start process, the second preparation setting flag set in the state information storage area 106c is cleared, the first preparation setting flag is set in the state information storage area 106c, and the gaming state is changed to the first preparation state. And Also, 3 is set in the remaining game number counter.

  As described above, in the second preparation state, even if either the bell winning or the first re-game winning is achieved, the number of remaining games is not changed even if the second re-game winning is achieved without shifting to another gaming state. 3 is never set in the counter again. That is, in the second preparation state, the gaming state shifts to the first preparation state only when three games are performed under the second preparation state.

  If it is determined in step S603 that the current gaming state is not the second preparation state, it is determined in step S605 whether or not the current gaming state is the third preparation state. When the current gaming state is the third preparation state, the third transition determination process is performed in step S606, and then this process ends.

  In the third transition determination process, as shown in the flowchart of FIG. 21, it is determined in step S901 whether or not the first re-game winning is established based on the winning combination set in the previous payout determination process. If the first re-game winning is established, the process proceeds to step S902, and after the RT start process is performed, this process is terminated. In the RT start process, the third preparation setting flag set in the state information storage area 106c is cleared, and the RT setting flag is set in the state information storage area 106c to set the gaming state to the RT state. Also, 100 is set in the remaining game number counter. If it is determined in step S901 that the first re-game winning is not established, the process proceeds to step S903, and whether or not the bell winning is established based on the winning combination set in the previous payout determination process. judge. If the bell is established, the normal game start process is performed in step S904, and then this process ends. In the normal game start process, the third preparation setting flag set in the state information storage area 106c is cleared, and the game state is changed to the normal game state. If it is determined in step S903 that the Bell winning is not established, the value of the remaining game number counter is decremented by 1 in step S905, and whether or not the remaining game number counter value is 0 in step S906. Determine whether. If the value of the remaining game number counter is not 0, the process is terminated as it is. If the value of the remaining game number counter is 0, the process is performed after the first preparation start process is performed in step S907. finish. In the first preparation start process, the third preparation setting flag set in the state information storage area 106c is cleared, the first preparation setting flag is set in the state information storage area 106c, and the gaming state is changed to the first preparation state. And Also, 3 is set in the remaining game number counter.

  Thus, in the third preparation state, unlike the first preparation state, when the bell winning is achieved, the gaming state shifts to the normal gaming state instead of the RT state, and the game is performed when the first re-game winning is achieved. The state shifts to the RT state instead of the normal gaming state. Further, in the third preparation state, the game state does not shift to the second preparation state when the second re-game winning is established. Then, when the game is performed three times without establishing either the bell winning or the first re-game winning, the state shifts from the third preparation state to the first preparation state.

  In the slot machine 10, the effect of notifying whether the gaming state is the first preparation state to the third preparation state is not performed, and when transitioning to the normal gaming state or the RT state is performed. An effect to notify the gaming state is performed.

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

  The condition for shifting to the RT state is different between the first preparation state and the third preparation state, and the first preparation state is changed to the third preparation state, or the third preparation state is changed to the first preparation state. The configuration. By adopting such a configuration, it is possible to cause the player to guess the current game state and the transition condition to the RT state, and it is possible to suppress the game from becoming monotonous.

  When the bell winning is established, if the gaming state at that time is the first preparation state, the state shifts to the RT state, and if the gaming state at that time is the third preparation state, the state shifts to the normal gaming state. . Further, when the first re-game winning is established, if the gaming state at that time is the first preparation state, it shifts to the normal gaming state, and if the gaming state at that time is the third preparation state, the RT state is set. It was set as the structure which transfers. Thus, it is difficult for the player to grasp the transition condition to the RT state by setting the transition condition to the RT state in one preparation state as the transition condition to the normal gaming state in the other preparation state. It becomes possible. More specifically, for example, when a bell winning is established in the first game after the end of the BB state, the gaming state shifts to the RT state because it is in the first preparation state. It is assumed that the player who has experienced the event recognizes that the transition condition to the RT state is the establishment of the Bell prize. On the other hand, for example, after the BB state is completed, the game is played four times without any of the Bell prize, the first re-game prize, and the second re-game prize, and if the Bell prize is established in the fifth game, Since it is in the ready state, the gaming state shifts to the normal gaming state instead of the RT state. For this reason, if the player who has recognized that the transition condition to the RT state is the establishment of the Bell prize, when the player experiences the above event, the player's own recognition is wrong, and the transition condition to the RT state is other than that. This is because it is assumed to be recognized as being in the area. As a result, it is possible to make a game play not only in each preparation state but also in other game states while guessing what the conditions for transition to the RT state are, and it is preferable that the game is monotonous. It becomes possible to suppress.

  The establishment of the Bell prize or the establishment of the first replay prize was used as a condition for shifting to the RT state in the first preparation state and the third preparation state. Thus, by making the stop result of each of the reels 32L, 32M, and 32R a transition condition to the RT state, it is possible to entertain the current gaming state and the transition condition to the RT state. Certainly, it is possible to adopt a configuration in which a transfer lottery is performed to determine whether or not to shift to the RT state regardless of whether or not a prize has been established and the lottery result of the combination. However, in the case of such a configuration, it is very difficult to grasp the conditions for shifting to the RT state in a configuration including a plurality of preparation states that can shift to the RT state as in the present slot machine 10. . This may lead to the player giving up grasping the condition for transitioning to the RT state. On the other hand, when the stop result of each of the reels 32L, 32M, and 32R is used as the condition for transitioning to the RT state, by repeatedly playing the game, more specifically, by experiencing the transition to the RT state many times, the RT state It is possible to grasp the transition conditions. Therefore, it is possible to entertain the guessing of the current game state and the condition for shifting to the RT state.

  When the second re-game winning is established under the first preparation state, the game is shifted to the second preparation state in which the game returns to the first preparation state after three games. By adopting such a configuration, it becomes possible to make it difficult to grasp the current gaming state, and it is possible to provide pleasure for guessing the current gaming state. In addition, since it is configured not to shift to the normal game state and the RT state from the second preparation state, even if the transition to the normal game state and the RT state is not performed, even if the bell winning or the first re-game winning is established. An event that does not shift to the normal gaming state or the RT state can be generated. As a result, it is possible to make it difficult to grasp the condition for transitioning to the RT state, and it is possible to provide pleasure for estimating the condition for transitioning to the RT state.

  In each gaming state from the first preparation state to the third preparation state, the expected value for paying out medals per game is larger than the number of medals required per game. By adopting such a configuration, it is possible to prevent the player from erroneously recognizing that the player has transitioned to the normal gaming state despite the possibility of transitioning to the RT state and ending the game. It becomes.

  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 second preparation state that does not shift to the normal gaming state and the RT state is provided. However, the second preparation state may not be provided.

  (2) In the above-described embodiment, the second preparation state is a gaming state in which there is no possibility of shifting to the normal gaming state and the RT state, but it may be a gaming state in which there is a possibility of shifting to the RT state. Not too long.

  (3) In the above embodiment, the second preparation state is set only when the second regame winning is established in the first preparation state. However, instead of or in addition to this, the third preparation is performed. It is good also as a structure which transfers to a 2nd preparation state, when the 2nd re-game winning a prize is materialized under a state.

  (4) In the above embodiment, when the second preparation state is completed, the configuration returns to the first preparation state. However, the configuration may shift to the third preparation state, and the first preparation state and the third preparation state may be used. It is good also as a structure which performs predetermined | prescribed lottery etc. and determines which of a preparation state is made to transfer.

  (5) In the above embodiment, as the transition condition to the first preparation state, the end of the BB state or the second preparation state and the fact that three games were performed under the third preparation state, Although it was set as the structure provided, it is good also as a structure provided with other transition conditions. Other transition conditions include the establishment of a predetermined winning such as a cherry winning, winning a predetermined combination, playing a predetermined number of games under the normal gaming state, and exiting the RT state. It is done.

  (6) In the above embodiment, in each of the first preparation state to the third preparation state, the configuration is always started from the first preparation state. However, the configuration may be started from the second preparation state. And it is good also as a structure started from a 3rd preparation state. Moreover, it is good also as a structure which performs predetermined lottery etc. to determine from any of a 1st preparation state-a 3rd preparation state.

  (7) In the above embodiment, as a condition for ending the first preparation state to the third preparation state (that is, a transition condition to another game state), a case where a predetermined winning such as a bell winning is established, and a predetermined number of times Although the case where a game is performed is provided, the configuration may include other termination conditions.

  For example, when a cherry is won, regardless of whether or not a winning is established, if the current gaming state is the first preparation state, the state shifts to the RT state, and regardless of whether or not a winning is established, the gaming state at that time is the third preparation state. If it is in a state, it is set as the structure which transfers to a normal game state.

  For example, when a predetermined stop event (for example, a combination of “Replay” symbol, “Replay” symbol, “Bell” symbol) that does not become a winning combination stops on the active line, the gaming state at that time is the first preparation state If it exists, it will be set as the structure which transfers to RT state, and if the game state at that time is a 3rd preparation state, it will transfer to a normal game state.

  For example, the first preparation state and the third preparation state are configured to end only when three games are played. The first preparation state is shifted to the third preparation state when none of the bell prize, the first re-game prize, and the second re-game prize is established in the three games, and the three games When the first winning among the above winnings is a bell winning, it shifts to the RT state, and among the three winnings, the first winning among the winnings is the first re-game winning. In some cases, a transition is made to the normal game state, and the transition to the second preparation state is made when the first winning among the above three winnings is the second re-game winning. Similarly, the third preparation state shifts to the first preparation state when the bell winning and the first re-game winning are not established in the three games, and each of the above winnings in the three games is changed. When the first winning winning is a bell winning, it shifts to the normal gaming state, and when the first winning winning among the above three winnings is the first re-winning winning, it enters the RT state. The configuration is to be migrated.

  (8) In the above embodiment, the configuration is such that the transition to the RT state is not made unless the first preparation state or the third preparation state is passed. However, the transition to the RT state is made via the first preparation state or the third preparation state. Needless to say, it is possible to have a configuration including a case where the transition is made to the RT state without going through the first preparation state and the third preparation state.

  (9) In the above-described embodiment, it is configured not to produce an effect of notifying whether the gaming state is the first preparation state to the third preparation state. Specifically, after the BB state ends. A predetermined effect is continuously performed until a transition to the normal gaming state or the RT state, that is, while the gaming state is one of the first preparation state to the third preparation state. In such a configuration, it becomes possible for the player to recognize the first preparation state to the third preparation state as if they were one gaming state through a predetermined performance, and grasp the conditions for transition to the RT state. It is possible to make it difficult to do.

  (10) In the above-described embodiment, in the first preparation state and the third preparation state, the transition to the RT state or the normal gaming state is made on condition that a predetermined winning is achieved, but such a configuration is changed.

  For example, a winning combination can be established when the first combination that does not miss out when winning and the stop switches 42 to 44 are operated in a predetermined operation sequence, while being operated in another operation sequence. In the first preparation state, when the first combination is won, the RT state is entered, and when the second combination winning is established, the normal gaming state is entered. In the third preparation state, when the second winning combination is established, the state shifts to the RT state, and when the first combination is won, the state shifts to the normal gaming state.

  For example, when the stop switches 42 to 44 are operated in a predetermined operation order, a winning can be established, but when the stop switches 42 to 44 are operated in another operation order, there is provided a push order that causes a miss. In the preparatory state, when the push forward winning combination is won, if the push forward winning prize is established, the state shifts to the RT state, and if the push forward winning prize is not established, the state shifts to the normal gaming state. In the case where the push forward winning combination is won, the RT state is entered if the push winning prize is not established, and the normal gaming state is entered if the push winning prize is established.

  For example, it has a role that can be missed depending on the operation timing of the stop switches 42 to 44 in the case of winning, and in the first preparation state, if the winning is won, if the winning is established, the RT state is entered, If the winning is not established, the game is shifted to the normal gaming state. In the third preparation state, if the winning combination is won, if the winning is not established, the game moves to the RT state, and if the winning is established, the game moves to the normal gaming state. The configuration is as follows.

  (11) 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.

  (12) In the above embodiment, the slot machine having the BB state has been described. However, the present invention is not limited to such a configuration, and other game states such as the RB state and the SB state are provided instead of the BB state. It may be a slot machine. In the above embodiment, the slot machine having the preparation state in which the transition condition to the RT state changes has been described. However, the slot machine has the preparation state in which the transition condition to the AT state or the ART state changes. May be.

  (13) In the above embodiment, it is determined whether or not a start command is generated after three medals are bet. However, the start command is also issued after one bet or two bets. It goes without saying that it may be configured to determine whether or not it has occurred.

  (14) In the above-described embodiment, as a privilege to be given, in addition to the privilege that the game state shifts and the privilege of re-playing, it is configured to include a privilege to pay out medals, but is limited to this configuration Instead, any configuration may be used as long as the player is given some kind of privilege. For example, a configuration in which a prize other than a medal is paid out instead of a medal to pay out a medal may be used. Further, in a slot machine that does not have an actual medal insertion or medal payout function and manages credits owned by a player, an increase in credited medals corresponds to provision of a privilege.

  (15) In the above embodiment, a slot machine having three reels arranged in parallel and having five lines as effective lines has been described. However, the present invention is not limited to this configuration. For example, five reels arranged in parallel It may be a slot machine provided or a slot machine having seven effective lines.

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

  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.

Gaming machines Circulation display means (reels 32L, 32M, 32R) for cyclically displaying a plurality of kinds of patterns (designs);
Start operation means (start lever 41, first to third credit insertion switches 56 to 58) operated to start the cyclic display of the pattern;
Lottery means (lottery processing function of the main control device 101) for lottery of the role;
Stop operation means (stop switches 42 to 44) operated to stop the cyclic display of the pattern;
Based on the fact that the winning symbol corresponding to the winning combination won in the effective lot (effective line) formed a predetermined combination (such as a combination of small role symbols) and stopped, In a gaming machine provided with a privilege granting means for granting a privilege (medal payout processing S211 etc. of the main control device 101)
First transition means (first preparation start processing function S517 of the main control device 101) for transition to a first predetermined period (first preparation state);
First transition destination determining means for determining whether to shift from the first predetermined period to a first specific period (normal game state) or a second specific period (RT state) that is more advantageous to the player than the first specific period. (First transition determination processing function S602 of the main control device 101);
Second transition means (third preparation start processing function S709 of the main control device 101) for transitioning from the first predetermined period to the second predetermined period (third preparation state);
Second transition destination determination means (second transition determination processing function S604 of the main control device 101) for determining whether to shift from the second predetermined period to the first specific period or the second specific period;
Return means for returning from the second predetermined period to the first predetermined period (first preparation start processing function S907 of the main controller 101 in the third preparation state),
The case where the first migration destination determination unit determines to shift to the second specific period and the case where the second migration destination determination unit determines to shift to the second specific period are configured differently. A gaming machine characterized by

  According to this gaming machine, the case where it is determined to shift to the second specific period in the first predetermined period is different from the case where it is determined to shift to the second specific period in the second predetermined period, Furthermore, the process shifts from the first predetermined period to the second predetermined period or returns from the second predetermined period to the first predetermined period. By adopting such a configuration, what is the condition that is determined when the player guesses whether the current game period is the first predetermined period or the second predetermined period or shifts to the second specific period. It is possible to cause the player to guess whether there is any, and it is possible to suppress the game from becoming monotonous.

  1. gaming machine In the gaming machine 1, the first transfer destination determination means determines that the first condition (first regame winning establishment) is to be transferred when the first condition (first regame winning is established) and the second condition (bell winning) When the second condition is satisfied, the second specific period is determined to be transferred, and the second transfer destination determination unit is determined to be transferred to the first specific period when the second condition is satisfied. In addition, the gaming machine is configured to determine to shift to the second specific period when the first condition is satisfied.

  According to this gaming machine, when the first condition is satisfied, the first specific period is entered during the first predetermined period, while the second specific period is entered during the second predetermined period. Further, when the second condition is satisfied, the process shifts to the second specific period if it is the first predetermined period, and shifts to the first specific period if it is the second predetermined period. By adopting such a configuration, even if the same condition is satisfied, it is possible to change the destination depending on whether it is the first predetermined period or the second predetermined period, and the transition condition to the second specific period It is possible for the player to make it difficult to grasp.

  2. gaming machine In the gaming machine 2, first condition determining means (first regame winning establishment determination processing function S703, S901 of the main controller 101) for determining whether or not the first condition is satisfied, and the second condition are Second condition determination means (Bell winning establishment determination processing functions S701 and S903 of the main control device 101) for determining whether or not the condition is satisfied, and the first condition determination means includes a combination of the first pattern (first re-establishment). When the game symbol combination) stops at the effective position, it is determined that the first condition is satisfied, and the second condition determination unit stops the second symbol combination (bell symbol combination) at the effective position. A gaming machine characterized by determining that the second condition has been satisfied.

  According to this gaming machine, it is determined that the first condition is satisfied when the combination of the first pattern stops at the effective position, and the second condition is satisfied when the combination of the second pattern stops at the effective position. Determined. Even if the same condition is satisfied depending on whether it is the first predetermined period or the second predetermined period, in a configuration in which the transfer destination changes, the player must grasp the transfer condition to the second specific period. There is a possibility of giving up. However, the transition condition to the second specific period and the current game period are estimated by using the combination of the first pattern and the second pattern, that is, the stop result of the pattern as the first condition and the second condition. It is possible to entertain.

  Gaming machine4.
