Description

  The present invention relates to a gaming machine that includes a main effect display device and a sub-effect display device.

  Conventionally, there is, for example, a slot machine as this type of gaming machine.

  In a conventional general slot machine, three display windows are formed large on the front center panel facing the player, and three main reels are installed behind each display window. A plurality of symbols are drawn on the outer periphery of each main reel, and the player sees the combination of symbols displayed when each main reel is stopped, and grasps the lottery result of the winning mode. The lottery of the winning mode is performed for each game by the main control circuit configured on the main board inside the machine. In addition, there is a machine in which a sub-reel for providing an effect display for assisting an effect display by the main reel is provided on the front of the device above the main reel. The sub reel is generally smaller than the main reel, and its rotation is controlled by a sub control circuit provided on the sub control board.

  When a player inserts a medal and operates the start lever, the main reel starts to rotate under the control of the main control circuit, and the game is started. During the rotation of the main reel, a symbol moving at high speed is observed in each display window. In addition, on the sub reels, a symbol that enhances the effect of the main reel is displayed simultaneously with the rotation of the main reel. When the stop button is pressed by the player, the main reel is controlled to stop according to the operation timing. When the main reels are stopped and a predetermined symbol combination is aligned on the activated winning line, a winning actually occurs, and a predetermined number of medals are paid out from the medal payout opening to the medal tray. As the winning mode, there are a small hitting mode such as a bell, a watermelon, and a cherry, a medium winning mode such as a regular bonus (RB), and a big win mode such as a big bonus (BB). A player generally plays a game in expectation of a bonus winning mode such as RB or BB.

  However, the main control circuit for controlling the main reel in the conventional gaming machine is subject to various restrictions due to regulations such as customs business regulations and laws concerning suitability of business. For this reason, the conventional main reel can only perform rotation control in accordance with laws and regulations, and the capacity of the memory that can be mounted in the main control circuit is limited. As a result, the effect display of the main reel executed by the main CPU (central processing unit) of the main control circuit can be performed only within a limited restriction range, and an interesting and complicated effect display cannot be performed.

The present invention has been made to solve such a problem, a start operation detection means for detecting an operation of a game start means for starting a game,
A main control circuit that has a signal sending means for sending a signal and performs a winning mode lottery process for drawing a winning mode when the operation of the game starting unit is detected by the starting operation detecting unit;

A main effect display device for displaying a plurality of main symbols respectively drawn on a plurality of main reels on a main display window;
A sub-effect that displays, on the sub-display window, a plurality of sub-designs corresponding to each of the plurality of main symbols depicted on a plurality of sub-reels configured smaller than the main effect display device. A display device;
A stop operation detecting means for detecting an operation of the effect display stop means for stopping the rotation of the sub reel of the sub effect display device;
When the predetermined symbol combination of the sub-symbol corresponding to the winning mode selected in the winning mode lottery process is stopped and displayed on the auxiliary stage display device by the effect display stop means, the winning mode selected according to the winning mode lottery process is selected. In a gaming machine provided with a privilege granting means for granting a privilege to a player,
The main control circuit
When the operation of the game start means is detected by the start operation detecting means, the reel rotation signal for starting the rotation of the sub reel and rotating the main reel in synchronism with the sub reel and the winning lottery selected by the winning mode lottery process A start command including the type of aspect is sent to the sub-control circuit by the signal sending means,
When the operation of the effect display stop means is detected by the stop operation detection means, the amount of rotation of the sub reel necessary for displaying the sub symbols constituting the predetermined symbol combination on the sub display window is represented by the number of symbols of the symbols. And determining the number of sliding frames within the first range, sending the determined number of sliding frames to the sub-control circuit by the signal sending means, and the sub-pattern when the stop operation detecting means detects the operation of the effect display stopping means After the secondary reel is rotated from the position of the determined number of sliding frames, the secondary reel is stopped and the main reel is stopped and displayed in synchronization with the secondary reel stopped by the effect display stop means. A signal is sent to the sub-control circuit by the signal sending means, and all the sub-reels of the sub-effect display device are stopped and a winning combination indicating the combination of sub-patterns actually arranged in the sub-effect display device is displayed. When the type of the game matches the type of winning mode selected by the winning mode lottery process and the winning flag is normal, the winning command including the information on the winning flag is sent to the sub-control circuit by the signal sending means. ,
The sub-control circuit
When a reel rotation signal is received by the signal receiving means, a reel rotation process of the main reel is performed,
When a reel stop signal is received by the signal receiving means, the type of winning mode is identified from the start command received by the signal receiving means, and when the lose winning mode is identified, the reel stop signal is received. The main reel is rotated by the number of sliding frames determined by the main control circuit within the first range received by the signal receiving means from the position of the main symbol, and then stopped, and the winning mode other than lost is selected by lottery When it is identified, the number of sliding symbols is determined within a second range that includes the first range and is wider than the first range, and from the position of the main symbol when the reel stop signal is received. , Stop after rotating the main reel for the number of sliding frames determined by this lottery,
When a winning command is received by the signal receiving means, a reel reverse rotation lottery process for determining whether or not to rotate the main reel in a direction opposite to the direction in which the main reel has been rotated is performed. When winning by lottery in the rotation lottery process, a reel reverse rotation process for reversely rotating the main reel is performed.

  According to this configuration, the rotation direction of the main reel of the main effect display device is reversed without restriction, for example, when a lottery is performed in the reel reverse rotation lottery process.

  Further, the present invention is characterized in that the sub control circuit makes the rotation speed of the main reel different from the rotation speed of the sub reel.

  According to this configuration, the rotation speed of the main reel can be set to an arbitrary speed without being restricted by regulation.

  As described above, according to the present invention, as described above, the sub-control circuit determines, for example, whether or not to rotate the main reel in a direction opposite to the direction in which the main reel has been rotated. When a reverse rotation lottery process is performed, and a lottery is performed in this reel reverse rotation lottery process, a reel reverse rotation process is performed to reversely rotate the main reel. When the lottery in the rotary lottery process is won, the game is reversed. For this reason, the player can enjoy the effect of reversing the rotation direction of the main reel, which has not been conventionally performed on the main effect display device, and the fun of the game is improved.

  Further, when the sub control circuit is configured to make the rotation speed of the main reel different from the rotation speed of the sub reel, the rotation speed of the main reel can be set to an arbitrary speed without being restricted by regulation. For this reason, since the effect display by the main effect display device is performed at a speed not limited by the effect display speed of the sub-effect display device, the player can enjoy this new effect display by the main effect display device, and Will improve.

  FIG. 2 shows symbol rows drawn on the outer peripheral surfaces of the main reels 2, 3, 4. Each symbol row is configured by arranging 21 types of symbols, and corresponds to the first main reel 2, the second main reel 3, and the third main reel 4 in order from the left in the drawing. Each symbol is assigned a code number of “1 to 21”, and the main reels 2, 3 and 4 are rotationally driven so that the normal symbol row moves downward in the figure. There are six types of symbols: “red 7”, “blue 7”, “bell”, “watermelon”, “cherry”, and “replay”. “Blank” means that there is no symbol display and is blank.

  FIG. 3 shows symbol rows drawn on the outer peripheral surfaces of the sub reels 35, 36, and 37. Each of these symbol columns is also configured by arranging 21 types of symbols, and corresponds to the first sub reel 35, the second sub reel 36, and the third sub reel 37 in order from the left in the drawing. Each of these symbols is also given a code number of “1 to 21”, and each of the sub reels 35, 36, and 37 is rotationally driven so that the normal symbol row moves downward in the figure. There are five types of symbols: “Seven”, “★”, “◆”, “▲”, and “Replay”. Again, “blank” means that there is no symbol display and is blank.

  The symbols “Seven” on the sub reels 35 to 37 correspond to “red 7” and “blue 7” on the symbol columns of the main reels 2 to 4, and the symbol “★” indicates “ “Bell” and symbol “♦” correspond to “watermelon” in the symbol column of main reels 2 to 4, and symbol “▲” corresponds to “cherry” in the symbol column of main reels 2 to 4. The symbols “replay” and “blank” are common to the sub reels 35 to 37 and the main reels 2 to 4. That is, the sub reels 35 to 37 and the main reels 2 to 4 are partially different in the type of individual symbols, but are the same in the symbol arrangement configuration.

  Next, an outline of (1) general game, (2) R · B game, and (3) B · B game performed in the slot machine 1 according to the present embodiment will be described.

  (1) General game

  In the general game, three symbol combinations of the symbols “bell” and “watermelon” are arranged on the winning lines of the main reels 2 to 4, and the three symbol combinations of the symbols “★” and “◆” are the sub reels 35 to 35. When one symbol “Cherry” stops on the winning line of the first main reel 2 and one symbol “▲” stops on the first sub-reel 35, a small win is won, and each of the 12 symbols, Eight or four payouts are paid out to the player and one game ends. In addition, when three combinations of “Replay” symbols are aligned on the pay lines of the main reels 2 to 4 and three combinations of “Replay” symbols are aligned on the sub reels 35 to 37, the medal is not inserted. But you can play the game again.

  Further, if the symbol combinations arranged on the winning lines of the main reels 2 to 4 do not correspond to any of the payout tables, “out of” (no payout) is set. At this time, none of the winning symbol combinations are arranged on the sub reels 35 to 37.

  Also, if the combination of the three symbols of the symbol “Red 7” is aligned with the winning lines of the main reels 2 to 4, a big win is won, and after 15 medals are paid out, a plurality of general games and bonus games are set as a set. Move to the following B / B game that can be played once. Also, if the three symbol combinations of the symbol “Blue 7” are aligned on the winning lines of the main reels 2 to 4, a win is made and a bonus game can be played once after 15 medals are paid out. Transition to R / B game. In the case of these bonus winnings, the sub reels 35 to 37 include three symbols “seven” of code numbers corresponding to the code numbers of “red 7” or “blue 7” in the symbol row of the main reels 2 to 4. The symbol combination is complete.

  (2) R / B game

  The R / B game occurs when the above symbol combinations are arranged on the main reels 2 to 4 and the sub reels 35 to 37 during a general game. In the R / B game, a single-medal game called a jack game can be performed a plurality of times. In this jack game, when three combinations of “replay” symbols are arranged on the winning lines L1 of the main reels 2 to 4, a jack game winning occurs and eight medals are paid out. The jack game also causes “out of game”, but the jack game prize is generated with a high probability of about 9/10. This R / B game ends when, for example, a jack game winning is generated eight times, or when the total number of jack games executed during the R / B game reaches, for example, twelve.

  (3) B / B game

  (i) The B / B game is composed of a plurality of sets of the above-mentioned R / B game and a general game. When the B / B game occurs, first, a general game is executed. In the general game during the B / B game, a “out of game” occurs, but the probability of winning a small hit with the symbols “bell”, “watermelon”, and “cherry” is higher than that during the general game other than during the B / B game Occurs.

  (ii) In addition, when three combinations of “replay” symbols are arranged in the general game in the B / B game, eight coins are paid out.

  (iii) After that, the game shifts to a bonus game in which a plurality of jack games can be performed. The bonus game in the B / B game is also terminated when, for example, a jack game prize is generated 8 times or the total number of jack games executed during the bonus game reaches 12 times, for example.

  (iv) When the bonus game ends, the general game in the B / B game described in (i) above is performed again, and the symbol combination described in (ii) above occurs during this general game. Thereafter, the bonus game described in (iii) above is further performed. The B / B game is a repetition of a set of general games and bonus games shown in the above (i) to (iii). When this set is performed a predetermined number of times, for example, twice, the B / B game is End. However, during this B / B game, the total number of games in the general games (i) and (ii) above, in other words, the total number of games excluding the number of jack games in the bonus game (iii) above is a predetermined number. For example, the B / B game ends when the number of times exceeds 30.

  4 shows the configuration of the main control circuit configured on the main control board 61 that controls the game processing operation of the slot machine 1 described above, and FIG. 5 shows the configuration of the sub control board 62 separately from the main control circuit. 2 shows the configuration of the sub-control circuit.

  The control unit in the main control board 61 shown in FIG. 4 includes a microcomputer (hereinafter referred to as a microcomputer) 63 as a main component, and a circuit for random number sampling is added thereto. The microcomputer 63 includes a main CPU (central processing unit) 64 that performs a control operation according to a preset program, a program ROM (read only memory) 65 that is a program storage means, and a control RAM (random access) with a backup function. -Memory) 66.

  Connected to the CPU 64 are a clock pulse generation circuit 67 and a frequency divider 68 for generating a reference clock pulse, a random number generator 69 for generating a random number in a certain range, and a random number sampling circuit 70 for specifying one of the generated random numbers. Has been. Further, an I / O port (input / output port) 71 for transmitting / receiving a signal to / from a peripheral device (actuator) described later is connected. The microcomputer 63, the random number generator 69, and the random number sampling circuit 70 constitute a winning mode lottery means for performing a winning mode lottery process for each game. The program ROM 65 has a storage section that stores a probability lottery table, a symbol table, a winning symbol combination table, a sequence program, and the like.

  FIG. 6 conceptually shows a probability lottery table used in a general game stored in the program ROM 65. This probability lottery table is used to divide the random numbers extracted by the sampling circuit 70 during the general game into each winning combination, and data for dividing a predetermined range of random numbers generated by the random number generator 69 into each winning combination. I remember it. In the figure, a1 to a3, b1 to b3, c1 to c3, d1 to d3, e1 to e3, f1 to f3 are numerical data set in advance, and the random numbers extracted by the sampling circuit 70 are divided into each winning combination. Used when This data uses a combination of numerical values “a1 to f1” when the number of inserted medals is one, “a2 to f2” when two, and “a3 to f3” when three. It is done.

  These numerical values are normally set to a magnitude relationship of “a <b <c <d <e <f”, and if the extracted random number value is less than c, a small win prize (small hit) is obtained. In this case, less than a In this case, a request flag per “bell” is set, a request flag per “watermelon” is set when a is less than b and a request flag per “cherry” is set when b is less than c. Further, if the extracted random number value is not less than c and less than d, a request flag for “replay” is set. Further, if the extracted random number value is d or more and less than e, it becomes a medium winning prize (medium hit) and a request flag per “RB” is set. A big hit) and a request flag per “BB” is set. On the other hand, if it is greater than or equal to f, it will be “out of” without winning. In other words, the winning combination is determined according to which numerical range the one sampled random number value belongs to, and is represented by the winning request flag.

  The bonus request flag “BB” or “RB” is carried over to the game after the flag is set, and the symbol combination “BB” or “RB” is stopped and displayed on the activated pay line, and the bonus winning is actually performed. If this happens, the bonus requirement flag is cleared. Flags other than the bonus requirement flag are valid only in the game in which the flag is set, and are cleared at the end of the game and are not carried over after the next game.

  In the present embodiment, an example of a lottery value when three bets are placed in the probability lottery table shown in FIG. 6 is shown in the table shown in FIG.

  The random number generator 69 generates a total of 16384 random numbers ranging from 0 to 16383. The internal winning combination of “Bell”, “Watermelon” and “Cherry” will be selected by the sampling circuit 70 when random numbers with random numbers 1432, 830 and 63 of 0 to 1431, 1432 to 2261 and 2262 to 2324 are extracted. Is done. In addition, the “replay” internal winning combination is drawn when a random number with a random number width 2245 of 2325 to 4569 is extracted. The “RB” internal winning combination is drawn when a random number 28 having a random number width of 4570 to 4597 is extracted, and the “BB” internal winning combination is selected when a random number having a random number width 55 of 4598 to 4652 is extracted. . When the remaining random numbers with the random number width 11731 of 4653 to 16383 are extracted, “lost” is obtained.

  The symbol table (not shown) stored in the program ROM 65 associates the rotational positions of the sub-reels 35 to 37 with the symbols drawn in the symbol rows, and represents the symbol rows as symbols. Is. In this symbol table, a code number sequentially assigned for each fixed rotation pitch of each of the sub reels 35 to 37 and a symbol code indicating a symbol provided corresponding to each code number are stored.

  The program ROM 65 stores a winning symbol combination table (not shown). This winning symbol combination table stores a symbol code of each winning symbol combination shown in the payout table, a symbol code of a symbol combination constituting a “reach eye”, a winning determination code representing each winning, a winning medal payout number, etc. Has been. Here, “reach” means that the B / B game is close to the player when the B / B game flag has been set and the B / B game flag has been set. Symbol combination. Further, in the program ROM 65, a sequence program for executing a game on the slot machine 1 is stored.

  As main actuators whose operation is controlled by a control signal from the microcomputer 63, a stepping motor 45 for rotating and driving the sub reels 35, 36, and 37, various lamps (medal insertion number display lamps 9 to 13, Replay display lamp 14, game stop display lamp 15, WIN lamp 16, start lamp 17, insert lamp 18, reel back lamp 46 built in sub-reels 35 to 37), various display units (stored number display unit 19, chance display) There are a container 20, a bonus count display section 21, a winning dividend display section 22), and a hopper 72 for storing medals. These are driven by a motor drive circuit 73, each lamp drive circuit 74, each display unit drive circuit 75, and a hopper drive circuit 76, respectively. These drive circuits 73 to 76 are connected to the CPU 64 via the I / O port 71 of the microcomputer 63. Thus, in the present embodiment, the effect display of the sub reels 35 to 37 is controlled by the main control circuit configured on the main control board 61.

  As main input signal generating means for generating an input signal necessary for the microcomputer 63 to generate a control signal, the inserted medal sensor 8S for detecting a medal inserted from the medal slot 8 and the operation of the start lever 27 are used. There are a start switch 27S for detecting the stored medal, the aforementioned stored medal insertion switches 23 to 25, and the stored medal settlement switch 26. Further, there is a reel position detection circuit 77 that receives the output pulse signal from the photosensor and detects the rotational position of each sub reel 35, 36, 37. The photo sensor is included in the driving mechanism of each of the sub reels 35 to 37 and is not shown in the figure.

  The reel position detection circuit 77 counts the number of drive pulses supplied to each of the stepping motors 45 after the rotation of the sub reels 35 to 37 is started, and writes this count value in a predetermined area of the control RAM 66. Accordingly, the control RAM 66 stores a count value corresponding to the rotation position within one rotation range for each of the sub reels 35 to 37. The photosensor generates a reset pulse every time each of the sub reels 35 to 37 makes one rotation. The reset pulse is supplied to the CPU 63 via the reel position detection circuit 77, and the count value of the drive pulse counted by the control RAM 66 is cleared to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor 45 is eliminated every rotation.

  Further, as the input signal generating means, a reel stop signal circuit 78 that generates a signal for stopping the corresponding reel when the stop buttons 28, 29, and 30 are pressed, and the number of medals paid out from the hopper 72 are counted. There are a medal detection unit 72S and a payout completion signal generation circuit (not shown). This payout completion signal generating circuit pays out medals when the actually paid out medal count value input from the medal detection unit 72S reaches the payout number data represented by the count signal input from the display unit drive circuit 75. Generates a signal to detect completion of Each circuit constituting the input signal generating means is also connected to the CPU 64 via the I / O port 71.

  A sub-control unit communication port 79 is connected to the I / O port 71, and the microcomputer 63 sends a signal to the sub-control board 62 via the sub-control unit communication port 79. The sub control board 62 shown in FIG. 5 is provided with a main control unit communication port 88 for receiving this signal. Communication between the sub control unit communication port 79 and the main control unit communication port 88 is performed only in one direction from the sub control unit communication port 79 to the main control unit communication port 88. In this embodiment, the signal sent from the sub-control unit communication port 79 to the main control unit communication port 88 is a 7-bit command type indicating the control type, and an 8-bit or 24-bit length of the command. It consists of a set of parameters whose contents are represented.

  The control unit in the sub-control board 62 includes a microcomputer 81 as a main component, and a circuit for random number sampling is added thereto. Similarly to the microcomputer 63 on the main control board 61, the microcomputer 81 includes a sub CPU 82 that performs a control operation according to a preset program, a program ROM 83 that is a program storage unit, and a control RAM 84 with a backup function. A clock pulse generation circuit 85 for generating a reference clock pulse and a frequency divider 86 are also connected to the sub CPU 82. Further, the sub CPU 82 further transmits / receives signals to / from the main control unit communication port 88 and an actuator described later. / O port 87 is connected.

  Actuators whose operations are controlled by a control signal from the microcomputer 81 include a stepping motor 47 that rotationally drives the main reels 2, 3, and 4, and a reel back lamp 48 built in each of the main reels 2 to 4. The stepping motor 47 is driven by a motor drive circuit 49, and lighting of the reel back lamp 48 is controlled by a drive signal from the lamp drive circuit 50. These drive circuits 49 and 50 are connected to the sub CPU 82 via the I / O port 87 of the microcomputer 81.

  That is, in the present embodiment, the effect display of the main reels 2 to 4 is controlled by the sub control circuit configured on the sub control board 62. The sub-control circuit aligns the symbol combinations corresponding to the winning mode selected by the main control circuit with the winning lines of the main reels 2 to 4 and, as will be described later, when aligning the symbols within a desired range. Slide.

  In addition, as an input signal generating means for generating an input signal necessary for the microcomputer 81 to generate a control signal, a reel position that receives the output pulse signal from the photosensor and detects the rotational position of each main reel 2, 3, 4 There is a detection circuit 51. The photo sensor is included in the drive mechanism of each main reel 2 to 4 and is not shown in the figure.

  Similarly to the reel position detection circuit 77 that detects the rotation positions of the sub reels 35 to 37 on the main control board 61, the reel position detection circuit 51 is connected to each of the stepping motors 47 after the rotation of the main reels 2 to 4 is started. The number of supplied drive pulses is counted, and this count value is written in a predetermined area of the control RAM 84. Therefore, the control RAM 84 stores a count value corresponding to the rotation position within the range of one rotation for each of the main reels 2 to 4. The photo sensor generates a reset pulse every time the main reels 2 to 4 make one rotation. This reset pulse is given to the sub CPU 82 via the reel position detection circuit 51, and the count value of the drive pulse counted by the control RAM 84 is cleared to "0". By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor 47 is eliminated every rotation.

  A sound source IC (highly integrated circuit) 91 is connected to the I / O port 87. A sound ROM 94 storing sound data is connected to the sound source IC 91, and the sound source IC 91 emits sound from the speakers 33 and 33 via the power amplifier 95 under the control of the microcomputer 81. The microcomputer 81 controls the sound source IC 91 and the power amplifier 95 in accordance with instructions input from the main control board 61 via the main control unit communication port 88, and controls the medal insertion sound, start lever operation sound, stop button operation sound, bonus Sound effects such as game sounds during the game are output from the speakers 33 and 33. In addition, sound is output from the speakers 33 and 33 in a sound output pattern based on the game state fetched from the main control board 61 and an effect mode selected based on the winning flag.

  Next, the operation of the slot machine 1 controlled by the control circuit described above will be described.

  8 to 10 are flowcharts showing an outline of the game process controlled by the main CPU 64 of the main control board 61.

  First, an initialization process at the start of the game is performed (see step 101 in FIG. 8). Next, a RAM clear process at the end of the game is performed by the main CPU 64 to erase the data stored in the control RAM 66 at the end of the previous game (step 102). Subsequently, a re-play (replay) occurs as a result of the previous game, and the CPU 64 determines whether or not there is a request for automatic medal insertion (step 103). If there is an automatic insertion request, next, game medals corresponding to the insertion request are automatically inserted (step 104). On the other hand, if there is no automatic insertion request, the player then inserts a medal into the medal insertion slot 8 and inputs a detection signal from the medal sensor 8S, or inserts by operating the stored medal insertion switches 23-25. Wait for a signal to be input (step 105). Up to three medals can be inserted during a general game, and one medal can be inserted in a bonus game during a BB game or an RB game.

  Next, it is determined whether or not a start signal is input from the start switch 27S by operating the start lever 27 (step 106). If this determination is “YES”, it is next determined whether or not a predetermined time of 4.1 seconds has elapsed since the previous game (step 107). If 4.1 seconds have not elapsed, the game function waits until 4.1 seconds have elapsed after the wait function is activated (step 108). If the operation of the start lever 27 is performed before the elapse of 4.1 seconds, a non-reelable sound is emitted from the speakers 33 and 33 to notify the player that the weight function has been activated.

  When 4.1 seconds have passed since the previous game, next, a random number for lottery generated by the random number generator 69 is extracted by the sampling circuit 70 (step 109), and then for counting the above 4.1 seconds One game monitoring timer is set (step 110). Next, a probability lottery process is performed based on the random numbers extracted in step 110 (see step 111 in FIG. 9).

  This probability lottery process is performed by determining to which winning group the one random value specified by the sampling circuit 70 belongs to the probability lottery table (see FIG. 6). That is, the probability lottery data a1 to f1, a2 to f2, or a3 to f3 shown in each stage of the probability lottery table of FIG. 6 is set according to the number of medals inserted into the machine, and the probability lottery is performed. . When the probability lottery process shown in FIG. 7 is used and the probability lottery process is performed, for example, when a random number 2050 is extracted during a general game, the winning combination of small watermelons divided by the probability lottery data b3 is won. A request flag per watermelon is set in the control RAM 66. Further, for example, when the random number 4650 is extracted during the general game, it means that the BB game divided by the probability lottery data f3 is won, and a request flag per BB is set.

  When the probability lottery process is completed, a reel rotation process is then performed (step 112). In this reel rotation process, first, a predetermined area of the control RAM 66 in which the rotation positions of the sub reels 35 to 37 are written is initialized by the main CPU 64 at the start of the reel rotation. Subsequently, each of the sub reels 35 to 37 is initialized by the stepping motor 45. Driven by rotation. Subsequently, a reel rotation signal and a start command are transmitted (step 113). The reel rotation signal is a signal for rotating the main reels 2 to 4 controlled by the sub control board 62 in synchronization with the sub reels 35 to 37. The start command includes, in its parameters, the type of hit request flag set as a result of the probability lottery process and the gaming state at that time. The reel rotation signal and the start command are transmitted to the sub control board 62 via the sub control unit communication port 79 after the start signal is input from the start switch 27S to the main CPU 64.

  Next, it is determined whether or not any of the stop buttons 28 to 30 has been turned on (step 114). If it is not turned on, it is determined whether or not the automatic stop timer has become zero (step 115). The automatic stop timer is for automatically stopping the sub reels 35 to 37 and the main reels 2 to 4 after a predetermined time has elapsed when the stop buttons 28 to 30 are not operated for a predetermined time.

  If any one of the stop buttons 28 to 30 is turned on or the automatic stop timer reaches 0, the number of symbols to be drawn on the activated pay line, that is, the number of sliding symbols is determined (step). 116). The number of sliding frames is determined within a predetermined range, for example, 4 frames from the gaming state, winning request, number of control frames, symbol position, etc., and the number of frames from the activated winning line to the winning symbol is within the range of the control frame number. If it is within, it is determined as the number of sliding frames. The number of sliding frames is stored in a predetermined area of the control RAM 66. Next, a symbol code transmission process is performed (step 117), and the symbol code numbers of the sub reels 35 to 37 stopped by the main control substrate 61 are transmitted to the sub control substrate 62 side via the sub control unit communication port 79. The Subsequently, a sliding frame number transmission process is performed (step 118), and the sliding frame number determined in step 116 is transmitted to the sub control board 62 side via the sub control unit communication port 79.

  Thereafter, a stop request flag for the first stop reel is set, and in response to the stop request flag being set, reel pull-in control is performed in which the first stop reel is rotated by the determined number of sliding frames, and the sub reel The rotation of any one of the reels 35 to 37 is stopped (step 119). Subsequently, a reel stop signal transmission process is performed (step 120), and any one of the main reels 2 to 4 is stopped in synchronization with any one of the stopped sub reels 35 to 37. A reel stop signal is transmitted to the sub control board 62 side via the sub control unit communication port 79. Next, it is determined whether or not all the sub reels 35 to 37 are stopped (step 121). If the second reel and the third reel have not yet stopped, the process returns to step 114, and the above processes are repeated.

  When all the sub reels 35 to 37 are stopped, a winning search process is performed by the main CPU 64 (see step 122 in FIG. 10). In this winning search process, the type of the winning flag indicating the combination of symbols actually arranged on the activated winning line is matched with the type of the internal winning combination determined by the probability lottery process. Next, it is determined whether or not the winning flag is normal (step 123). If this determination result is not normal, for example, when the bell symbol combinations are aligned on the activated pay lines of the main reels 2 to 4, the winning request flag corresponding to the internal winning combination is a cherry flag. An illegal error is displayed on the payout number display section 22 (step 124).

  If the winning flag is normal, then a winning command is transmitted to the sub control board 62 side via the sub control unit communication port 79 (step 125). The parameter of this winning command includes information on the type of winning flag indicating the combination of symbols actually arranged on the activated winning line. Next, the game medal is stored or paid out according to the state at that time (step 126). In other words, if the game is played with credit, the number of stored coins displayed on the stored coin number display unit 19 is increased by the number of medals won by winning, and the game is played by inserting the medal into the medal slot 8. If the state is being performed, the number of medals acquired by winning a prize is paid out to the tray 31. When the medal is stored or paid out, the WIN lamp 16 is turned on, and an effect that promotes the joy of acquiring the medal is performed (step 127).

  Next, the main CPU 64 determines whether or not the current gaming state is operating the BB game or the RB game (step 128). If the BB game or the RB game is not in operation, the game processing by the main CPU 64 returns to step 102, and the next new game is started. If the BB game or RB game is in operation, the number of games of the BB game or RB game is checked by the main CPU 64 (step 129).

  Subsequently, the main CPU 64 determines whether or not the current gaming state is at the end of the BB game (step 130). If the BB game is over, a RAM clear process at the end of the BB game is performed on the control RAM 66 (step 131), and then the game process returns to step 102 to start the next new game. If it is not at the end of the BB game in step 130, the game process returns to step 102 and the next new game is started.

  Next, game processing controlled by the sub CPU 82 of the sub control board 62 will be described.

  FIG. 11 is a flowchart showing an outline of game processing controlled by the sub CPU 82. In the sub control board 62, various commands received from the main control board 61 side are always analyzed by the sub CPU 82, and various game processes based on the commands are appropriately performed (see step 201 in FIG. 11).

  FIG. 12 is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is a reel rotation signal command. In this reel rotation signal reception process, first, it is determined whether or not a reel rotation signal has been received (see step 211 in FIG. 12). This determination is performed by determining whether or not a reel rotation signal is transmitted from the main control board 61 side in the processing of FIG. 9, step 113 described above. If the reel rotation signal has been received, the reel rotation processing is then performed by the sub CPU 82 of the sub control board 62 (step 212). In this reel rotation process, first, a predetermined area of the control RAM 84 in which the respective rotation positions of the main reels 2 to 4 are written is initialized by the sub CPU 82 at the start of the reel rotation. 47 is rotationally driven.

  FIG. 13 is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is a symbol code. In this symbol code receiving process, first, it is determined whether or not a symbol code has been received (see step 221 in FIG. 13). This determination is performed by determining whether or not a symbol code is transmitted from the main control board 61 side in the processing of FIG. 9 and step 117 described above. If the symbol code has been received, the symbol code number (No.) is acquired from the received signal by the sub CPU 82 (step 222). This symbol code number is a code No. shown in the leftmost column of FIGS. It is. The acquired code number is stored in the control RAM 84 of the sub control board 62 (step 223).

  FIG. 14 is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is the number of sliding frames. In this sliding frame number receiving process, first, it is determined whether or not a sliding frame number has been received (see step 231 in FIG. 14). This determination is performed by determining whether or not the number of sliding frames is transmitted from the main control board 61 side in the process of FIG. 9, step 118 described above. If the number of sliding frames has been received, the number of sliding frames is acquired from the main control board 61 side by the sub CPU 82 (step 232), and the acquired number of sliding frames is stored in the control RAM 84 of the sub control board 62. (Step 233).

  FIG. 15 is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is a reel stop signal command. In this reel stop signal reception process, first, it is determined whether or not a reel stop signal has been received (see step 241 in FIG. 15). This determination is made by determining whether or not a reel stop signal is transmitted from the main control board 61 side in the processing of FIG. 9, step 120 described above. If the reel stop signal has been received, the sub CPU 82 refers to the symbol code number stored in the control RAM 84 in FIG. 13, step 223 (step 242). Thereafter, the internal winning flag is turned ON, and it is determined whether or not any winning mode other than the loss is established (step 243). This determination is performed by identifying the type of the hit request flag that is read from the start command transmitted from the main control board 61 side in the process of FIG.

  As a result of the above determination, if the main control circuit finds out that the lost winning mode has been drawn, the sub CPU 82 refers to the number of sliding symbols stored in the control RAM 84 in FIG. 14 and step 233, and refers to the symbol referred to in step 242. The rotation of any one of the main reels 2 to 4 is slid by the number of sliding frames referenced based on the code number and stopped (step 244). This sliding effect is performed within the range of 4 frames because the number of sliding frames determined in FIG. 9, step 116 on the main control board 61 side is within the range of 4 frames.

  If it is determined as a result of the above determination that the main control circuit has selected a winning mode other than lost, the sub CPU 82 performs a sliding frame number determination lottery, and the number of sliding frames determined by the lottery is determined. Then, the rotation of any one of the main reels 2 to 4 is slid and stopped (step 245). The sliding frame number determination lottery is performed with reference to the sliding frame number lottery table shown in FIG. 16 stored in the program ROM 83 of the sub-control board 62. In this lottery, one random number is extracted from the random numbers in the range of 0 to 1024 by the sub CPU 82, and by determining which random number category of the sliding frame number lottery table the extracted random number belongs to The number of sliding frames is determined. For example, when the random number 951 is extracted, the number of sliding frames is determined as 17 frames from the table.

  The expected value of the lottery process is set to 8.12 as shown in the figure, which is close to the predetermined range of 4 frames. Here, the expected value E is a value obtained by dividing the product of the size of each random number segment and the number of sliding frames shown in the figure by the total random number range 1024 (E = (25 × 1 + 25 × 2 + 36 × 3 +...) / 1024). In the table shown in the figure, the range of the number of sliding frames is 21 frames at the maximum. However, the range is not limited to this and can be set to a desired range.

  When the process of step 245 or step 244 is completed, the sub CPU 82 determines whether or not the reel stop process has been performed for all the main reels 2 to 4 (step 246). If the reel stop process is not performed for all the main reels 2 to 4, the process returns to step 241, and the reel stop process is performed for all the main reels 2 to 4.

  According to such a slot machine 1 according to the present embodiment, the effect display of the main reels 2 to 4 is controlled by the sub-control circuit configured on the sub-control board 62 which is not regulated by regulations. For this reason, it becomes possible to cause the main reels 2 to 4 to perform a complex and interesting display that is not restricted by regulations.

  In the slot machine 1 according to the present embodiment, the effect display is controlled by the main control circuit in which the sub reels 35 to 37 are configured on the main control board 61. Accordingly, the effect display of the main reels 2 to 4 is controlled by a sub-control circuit that is not regulated by laws and regulations, and the effect display of the sub-reels 35 to 37 is controlled by the main control circuit. For this reason, the sub reels 35 to 37 that provide the production assistance for the main reels 2 to 4 and do not require complicated control and memory capacity are sufficiently produced even by the main control circuit that is restricted and has limited memory capacity. Can be displayed.

  In the slot machine 1 according to the present embodiment, the sub-control circuit of the sub-control board 62 uses a combination of symbols corresponding to the winning mode selected by the main control circuit of the main control board 61 as a winning line for the main reels 2 to 4. The symbols are slid within a desired range, that is, 21 frames in this embodiment. For this reason, the sub-control circuit slides the symbols within a desired range without being restricted by the four frames restricted by the main control circuit when aligning the symbol combinations corresponding to the winning mode on the main reels 2 to 4. It can be made. As a result, it is possible to cause the main reels 2 to 4 to perform an interesting sliding effect that is not constrained by the conventional restriction frame.

  Further, in the present embodiment, as described above, when the sub-control circuit draws the lost winning mode in the main control circuit, in step 244 of the reel stop signal reception process shown in FIG. Slide symbol. When a winning mode other than lose is selected, the symbol is slid in a range selected from the range of 21 frames by a lottery in which the expected value 8.12 is close to 4 performed in step 245 of the reception process. Therefore, if a player performs a symbol slide effect in a range exceeding 4 frames, the player can recognize that a winning mode other than a loss has been won, and a symbol slide effect is performed within a range of 4 frames. It is possible to recognize that a lottery has been drawn with a high probability.

  Furthermore, if the player performs the symbol slide effect in the range of the expected value close to 4 frames, and the number of slide frames cannot be accurately recognized, the player becomes anxious about whether or not a lottery has been drawn. For this reason, in the slot machine 1 according to the present embodiment, the result of the internal lottery of whether or not the game is lost is notified to the player by this sliding effect that is not bound by the conventional restriction frame, and the player's slot machine game Interest is exciting.

  In the above embodiment, the case where the main effect display device and the sub effect display device are mechanical cylindrical main reels 2 to 4 and sub reels 35 to 37 has been described. However, these reels are imitated in a liquid crystal display device. And may be configured to be displayed. Even in this case, the same effects as those of the above-described embodiment can be obtained.

  Further, in this case, when a specific winning mode, for example, “BB” or “RB” bonus winning mode is selected by the main control circuit, the sub-control circuit configured on the sub-control board 62 simulates the liquid crystal display device. Thus, the color of the symbols of the main reels 2 to 4 displayed and the background color of the symbols can be changed.

  This process is performed, for example, like a winning command reception process shown in FIG. In other words, when the command received from the main control board 61 side is a winning command, the sub CPU 82 firstly includes the winning symbols actually arranged on the activated winning line included in the parameters of the winning command. It is determined whether or not the combination flag type is a bonus winning mode (FIG. 17, step 251). The winning command is transmitted from the main control board 61 side in the process of step 125 in FIG. Next, when the type of winning symbol combination is of the bonus winning mode, the sub CPU 82 sets the color of the symbols themselves of the main reels 2 to 4 displayed in a manner similar to the liquid crystal display device and the background color of the symbols. The color is changed (step 252).

  For example, when a BB game prize is generated, the color of the symbol “red 7” constituting the BB game prize symbol combination or the background color is changed to seven colors, or the red color is simply yellow Or discolor it. In addition, when an RB game winning is generated, the color of the symbol “blue 7” constituting the RB game winning symbol combination and the background color are changed to seven colors, or the blue one is simply green. Or discolor it.

  According to this configuration, the color of the symbol to be displayed and the background color of the symbol can be changed without being restricted by the liquid crystal display device constituting the main effect display device. Further, when the color of the symbol displayed on the liquid crystal display device or the background color of the symbol changes, the player can recognize that a specific winning mode, in this example, a bonus winning mode has been drawn. For this reason, the player can enjoy the color change effect of the symbol color and the background color of the symbol, which is not restricted by regulations, and the joy that the bonus winning mode and the like have been drawn is promoted by this color change effect.

  Next, a second embodiment in which the gaming machine according to the present invention is applied to a slot machine will be described.

  The slot machine according to the second embodiment has the same hardware configuration as the slot machine 1 according to the first embodiment described above. That is, the external appearance is shown in FIG. 1, the main control circuit configuration configured on the main control board is shown in FIG. 4, and the sub control circuit configuration configured on the sub control board is shown in FIG. Therefore, in the following description of the slot machine according to the second embodiment, the same or corresponding components as those of the slot machine 1 according to the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. To do.

  The slot machine according to the second embodiment is different in software configuration from the slot machine 1 according to the first embodiment described above. That is, the program ROM 65 of the main control board 61 stores a sequence program of the procedure shown in the flowcharts of FIGS. 18 to 20, and the program ROM 83 of the sub control board 62 shows the flowcharts of FIGS. 21 to 27. The sequence program for the procedure is stored.

  Next, the operation of the slot machine according to the second embodiment will be described.

  18 to 20 are flowcharts showing an outline of the game process controlled by the main CPU 64 of the main control board 61.

  The game processes from FIG. 18, steps 301 to 19 and step 316 are the same as the game processes from FIG. 8, steps 101 to 9 and step 116 in the first embodiment described above. That is, in the slot machine according to the second embodiment, as in the slot machine 1 according to the first embodiment, when the game medal is inserted into the insertion slot 8 and the start lever 27 is operated, the sub reels 35 to 37 are operated. Starts rotating, and the stop buttons 28 to 30 are operated to determine the number of sliding frames.

  When the number of sliding frames is determined in FIG. 19, step 316, in the slot machine according to the second embodiment, next, the stop request flag for the first stop reel is set, and this stop request flag is set. Accordingly, the reel pull-in control for rotating the first stop reel by the determined number of sliding frames is performed, and the rotation of any one of the sub reels 35 to 37 is stopped (FIG. 19, step 317). Subsequently, a reel stop signal transmission process is performed (step 318), and a reel stop for stopping one of the main reels 2 to 4 in synchronization with one of the stopped sub reels 35 to 37 is performed. The signal is transmitted to the sub control board 62 side via the sub control unit communication port 79. Next, symbol code transmission processing is performed (step 319), and the symbol code numbers of the sub reels 35 to 37 stopped by the main control substrate 61 are transmitted to the sub control substrate 62 side via the sub control unit communication port 79. The Thereafter, it is determined whether or not all the sub reels 35 to 37 have been stopped (step 320). If the second reel and the third reel have not been stopped, the process returns to step 314.

  When all the sub reels 35 to 37 are stopped, game processing shown in FIG. 20 and steps 321 to 330 is performed. These game processing is performed in FIG. 10 and steps 122 to 131 in the first embodiment. It is the same as the game processing up to.

  Next, game processing controlled by the sub CPU 82 of the sub control board 62 will be described.

  FIG. 21 is a flowchart showing an outline of game processing controlled by the sub CPU 82. Also in the second embodiment, in the sub control board 62, various commands received from the main control board 61 are always analyzed by the sub CPU 82, and various game processes based on these commands are appropriately performed (FIG. 21). , Step 401).

  FIG. 22 is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is a reel rotation signal command. In this reel rotation signal reception process, first, it is determined whether or not a reel rotation signal has been received (see step 411 in FIG. 22). This determination is made by determining whether or not a reel rotation signal is transmitted from the main control board 61 side in the processing of FIG. 19 and step 313 described above. If the reel rotation signal has been received, the reel rotation processing is performed by the sub CPU 82 of the sub control board 62 (step 412). In this reel rotation process, first, a predetermined area of the control RAM 84 in which the respective rotation positions of the main reels 2 to 4 are written is initialized by the sub CPU 82 at the start of the reel rotation. 47 is rotationally driven.

  FIG. 23 is a flowchart showing an outline of reception processing when the command received from the main control board 61 side is a reel stop signal command. In this reel stop signal reception process, first, it is determined whether or not a reel stop signal has been received (see step 421 in FIG. 23). This determination is made by determining whether or not a reel stop signal is transmitted from the main control board 61 side in the processing of FIG. 19 and step 318 described above. If the reel stop signal has been received, stop reel selection lottery processing is performed (step 422), and any one main reel 2 that is stopped in synchronization with the sub reels 35 to 37 being stopped. ~ 4 are selected by lottery. Next, stop control processing is performed for any one of the main reels 2 to 4 selected by lottery (step 423). Next, the sub CPU 82 determines whether or not the reel stop control process has been performed for all the main reels 2 to 4 (step 424). When the reel stop control process is not performed for all the main reels 2 to 4, the process returns to step 421, and the reel stop control process is performed for all the main reels 2 to 4.

  FIG. 24A is a flowchart showing the contents of the stop reel selection lottery process performed in step 422 described above. In this stop reel selection lottery process, first, a stop reel selection table is set in the control RAM 84 by the sub CPU 82 (see step 431 in FIG. 24). The stop reel selection table is shown in FIG. The main reels 2, 3, and 4 positioned on the left, middle, and right as viewed from the front of the device are selected with the same 1/3 selection ratio. Next, any one of the main reels 2 to 4 to be stopped is selected by the sub CPU 82 by lottery using the set stop reel selection table (step 432).

  FIG. 25 is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is a symbol code. In this symbol code receiving process, first, it is determined whether or not a symbol code has been received (see step 441 in FIG. 25). This determination is performed by determining whether or not a symbol code is transmitted from the main control board 61 side in the processing of FIG. 19 and step 319 described above. If the symbol code has been received, the symbol code number is acquired from the received signal by the sub CPU 82, and the acquired code number is stored in the control RAM 84 of the sub control board 62 (step 442).

  FIG. 26A is a flowchart showing an outline of the reception process when the command received from the main control board 61 side is a winning command. In this winning command reception process, first, it is determined whether or not a winning command has been received (see step 451 in FIG. 26). This determination is performed by determining whether or not a winning command is transmitted from the main control board 61 side in the processing of FIG. 20 and step 324 described above. If a winning command has been received, then a reel reverse rotation lottery process is performed (step 452). This reel reverse rotation lottery process is a process for determining whether or not to rotate the main reels 2 to 4 in the direction opposite to the direction in which the main reels 2 to 4 have been rotated.

  FIG. 6B shows a reel reverse rotation lottery table used for the reel reverse rotation lottery process, and this table is stored in the program ROM 83 of the sub control board. In the reel reverse rotation lottery, a random number lottery using random numbers in the range of 0 to 128 is performed by the sub CPU 82, and a random number extracted from this range is assigned to which random number value belongs to determine a loss. . If the random number extracted from the random number is 8, for example, it is a win, and if the random number is 83, for example, it is lost. Next, the sub CPU 82 determines whether or not the reel reverse rotation lottery has been won (step 453). If it is a win, a reel reverse rotation process is performed to reversely rotate the main reels 2 to 4 (step 454). On the other hand, if it does not win, the main reels 2 to 4 are rotated, and the symbol code numbers of the sub reels 35 to 37 stored in the control RAM 84 are referred to in FIG. The main reels 2 to 4 are stopped so as to synchronize with each other, that is, to synchronize with the sub reels 35 to 37.

  FIG. 27 is a flowchart showing the contents of the reel reverse rotation process performed in step 454 described above. In this reel reverse rotation processing, first, the symbol code number of the sub reels 35 to 37 stored in the control RAM 84 of the sub control board 62 is referred to, and the symbol of the same symbol code number as this symbol code number is assigned to the main reels 2 to 4. The main reels 2 to 4 are reversely rotated by the sub CPU 82 so as to be finally stopped (see step 461 in FIG. 27). Thereafter, the symbol of the same symbol code number as the referenced symbol code number is finally stopped and displayed on the main reels 2 to 4 (step 462).

  In the slot machine according to the second embodiment, as described above, the main reels 2 to 4 display a plurality of symbols in three columns of left, middle, and right, and the sub control circuit of the sub control board 62 is shown in FIG. In the stop reel selection lottery process shown in (a), the order of stopping the display row is determined by lottery using the stop reel selection table shown in FIG. Therefore, the order in which the display columns of the main reels 2 to 4 are stopped is the order determined by the lottery without being restricted by the regulation, and the player next determines which display column on the left, middle, or right stops. It is not possible to grasp in advance. For this reason, the player comes to observe which display column of the main reels 2 to 4 is next stopped, and the interest of the slot machine game is improved.

  In the slot machine according to the second embodiment, as described above, when the sub-control circuit of the sub-control board 62 is won in the reel reverse rotation lottery in step 452 shown in FIG. In step 454, an effect display for reversing the rotation direction of 4 is performed. Therefore, the rotation directions of the main reels 2 to 4 are reversed by the lottery without being restricted by regulation. For this reason, the player can enjoy the reversal effect in the rotation direction which has not been conventionally performed with the main reels 2 to 4, and the interest of the slot machine game is improved.

  In each of the above-described embodiments, the sub control circuit of the sub control board 62 synchronizes the rotation of the main reels 2 to 4 with the rotation of the sub reels 35 to 37 so that the rotation speed of the main reels 2 to 4 and the sub reels 35 to 35 are synchronized. The case where the rotational speed of 37 is the same has been described. However, you may comprise so that the rotational speed of the main reels 2-4 may differ from the rotational speed of the sub reels 35-37 by control of a sub control circuit. In the case of this configuration, the rotation speed of the main reels 2 to 4 can be set to an arbitrary speed without being restricted by regulation. For this reason, since the main reels 2 to 4 are rotated at a speed that is not limited by the rotation speed of the sub reels 35 to 37, the player can enjoy this new effect display by the main reels 2 to 4, and the slot machine game The interest is improved.

  Moreover, in each embodiment mentioned above, although the main effect display apparatus and the subeffect display apparatus demonstrated the case where it was set as the mechanical main reels 2-4 and the sub reels 35-37, these reels are displayed electronically. An electronic display device such as a liquid crystal display device may be used. Even in this case, the same operations and effects as the above-described embodiments can be obtained.

  In each of the above-described embodiments, the case where the gaming machine according to the present invention is applied to a slot machine has been described. However, the present invention includes a pachinko machine including a main effect display device and a sub-effect display device. It can be applied to other game machines such as a ball game machine. Even in this case, the same operations and effects as the above-described embodiments are achieved.
