Description

  The present invention relates to a gaming machine that determines a winning combination by lottery from a plurality of winning combinations based on detection of a start operation by a player.

  Conventionally, as such a gaming machine, there is a pachislot machine that stops the rotation of a reel in accordance with a player's operation. Generally, in a pachislot machine, when a medal as a game value is inserted into a medal slot and a start lever is operated, a winning combination is determined by lottery and a plurality of reels start rotating. When the stop button is operated after the rotation of each reel reaches a certain speed, the reel corresponding to the operated stop button stops rotating. If the combination of symbols corresponding to the winning combination determined by lottery when all reels stop rotating, medals are awarded to the player as a gaming value.

In the pachislot machine disclosed in Patent Document 1, lottery for determining the winning combination is performed by random lottery using a probability lottery table. In the probability lottery table, different numerical ranges for each winning combination are sequentially assigned from a predetermined random number range. In the random lottery, the upper limit of the numerical range assigned to each winning combination is subtracted from the extracted random number value, and when the subtraction result becomes negative, the winning combination assigned to the numerical range is determined as the winning combination in the unit game. Is done. On the other hand, when the subtraction result is positive, the same processing is performed on the upper limit value of the winning combination to be determined next until the subtraction result becomes negative.
JP 2002-78857 A (see paragraphs [0093] to [0098], FIG. 15 and FIG. 16)

  However, in the conventional pachislot machine disclosed in Patent Document 1, as described above, the calculation for subtracting the upper limit value of the numerical range assigned to each winning combination from the extracted random number value is performed for each upper limit value of each numerical range. When the value obtained as a result of the calculation is negative, the lottery of the winning combination has been completed, so the internal winning combination determined by extracting one random number value was limited to one type. . This has become a fixed concept for the player, and a new lottery system for winning the role has been awaited.

  In addition, since the determination of the winning role is directly linked to the balance of the amusement store where the pachislot machine is installed, the improvement of security related to it is a serious concern for the amusement shop. The winning combination was determined based solely on falling below the upper limit of the range, and the numerical range allocated to the winning combination related to payouts with a payout was biased toward younger numbers. For this reason, if the start operation is repeated at a certain timing due to cheating, random numbers in the biased numerical range will continue to be extracted, and the winning combination related to winning will be determined more than the originally planned probability, There was a problem that a lot of game value was given to the player, and the management of the game store where the pachislot machine was installed was deteriorated.

  Therefore, the present invention can bring about a new interest by overcoming the fixed concept of the player by introducing a new lottery system for the winning role, and can take effective measures against fraud. It is an object of the present invention to provide a gaming machine that can satisfy both of the demands of the game store.

To this end, the present invention provides a predetermined display based on symbol display means for displaying a plurality of symbols, start operation detection means for detecting a start operation by a player, and detection of the start operation performed by the start operation detection means. Random number extracting means for extracting a random number from a random number range, and a numerical range included in a predetermined random number range according to a predetermined winning combination, and a lower limit and an upper limit of other numerical ranges included in the predetermined random number range A lottery value prescribing means that prescribes a value according to a specific winning combination different from a predetermined winning combination, and a random number extracting means that compares the random number value extracted by the random number extracting means with both the lower limit value and the upper limit value. A first winning combination determining means for determining a predetermined winning combination based on the fact that the extracted random number belongs to a numerical range, and a specific winning combination based on the fact that the random number extracted by the random number extracting means belongs to another numerical range A second winning combination determining means for determining the symbol, a symbol changing means for changing the symbol displayed by the symbol display means based on the detection of the starting operation performed by the starting operation detecting means, and detection of the stop operation by the player Based on the stop operation detection means to be performed, the detection of the stop operation performed by the stop operation detection means, and the winning combination determined by the first winning combination determining means or the winning combination determined by the second winning combination determining means The game control is performed when a predetermined symbol combination is stopped and displayed by the symbol display means as a result of the stop control by the stop control means. Means and
The lottery value defining means is characterized in that at least a part of a numerical range corresponding to a predetermined winning combination and another numerical range corresponding to a specific winning combination are overlapped.

  According to this configuration, since a numerical range corresponding to a predetermined winning combination and another numerical range corresponding to a specific winning combination different from the winning combination are defined at least partially, random number extraction If the random numbers extracted by the means belong to this overlapping numerical range, a plurality of winning combinations of a predetermined winning combination and a specific winning combination corresponding to each numerical range are determined. Therefore, it is possible to provide a new winning combination lottery system capable of determining a plurality of winning combinations at a time using only one random value and one lottery value defining means. Further, since it is not necessary to provide a plurality of lottery value defining means, it is not necessary to increase hardware resources.

  In addition, other numerical ranges assigned to a specific winning combination are determined with a lower limit value and an upper limit value. Therefore, it is not always necessary to provide them in order, and it is possible to provide each numerical range in an irregular or overlapping manner. Become. For this reason, even if the start operation is repeated at a certain timing due to fraud, the extracted random number value does not continue to be in the numerical value range corresponding to the winning combination related to winning. Therefore, the winning combination relating to the winning is not determined more than the originally scheduled probability, and the management of the game store where the gaming machine is installed is not deteriorated.

  As a result, by introducing a new lottery system for winning roles, it is possible to break down the fixed concept of players and create new fun, and to take effective measures against fraudulent acts. It is possible to provide a gaming machine that can satisfy both requirements. Moreover, since the random number extracted by the random number extraction means is compared with both the lower limit value and the upper limit value only for a specific winning combination, the amount of data used for game processing is reduced compared to the case where this determination is always performed. This can reduce the hardware resources required.

  According to the present invention as described above, it is possible to provide a gaming machine capable of satisfying the demands of both the player and the gaming store as described above.

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 program ROM 65 has a storage section that stores various tables, sequence programs, and the like. The program ROM 65 stores a winning symbol combination table (not shown). In this winning symbol combination table, the symbol code of each winning symbol combination displayed on the payout display unit 39, the symbol code of the symbol combination constituting the “reach eye”, the winning determination code representing each winning, the number of winning medal dividends, etc. Is remembered. Here, the reach eye is a symbol combination that suggests that a combination of symbols related to the operation of the bonus can be displayed to the player in the internal winning state. This winning symbol combination table is referred to during stop control of the reels 2 to 4 and when searching for a display combination after all reels are stopped. Further, in the program ROM 65, a sequence program for executing a game with the pachislot machine 1 is stored.

  The main actuators whose operation is controlled by a control signal from the microcomputer 63 include a stepping motor 45 that rotationally drives the reels 2 to 4, various lamps (BET lamps 13 to 15, a start lamp 17, a WIN lamp 19, an insert lamp. 21), various display units (game operation indicators 9 to 12, stored number display unit 16, bonus count display unit 18, payout number display unit 20), and 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 main CPU 64 via the I / O port 71 of the microcomputer 63.

The microcomputer 63, the hopper 72, the medal detection unit 72s, the hopper driving circuit 76, and the payout completion signal generation circuit have symbol combinations corresponding to the internal winning combination predetermined by the symbol display means as a result of the stop control by the stop control means. When the stop display is made, it constitutes game value giving means for giving the game value as a medal.

  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. 6 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 the present 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 a maximum 24-bit length command content. It is composed of the parameters represented.

  The sub control board 62 performs a predetermined effect based on a control signal from the main control board 61. The control unit in the sub-control board 62 is configured with the microcomputer 81 as a main component. 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.

  As actuators whose operation is controlled by a control signal from the microcomputer 81, there are reel back lamps 47a to 47c built in the reels 2 to 4, respectively. Lighting of these back lamps 47 a to 47 c is controlled by a drive signal from a lamp drive circuit 89 connected to the I / O port 87.

An RB gaming state internal lottery table is determined as the lottery table.

  FIG. 9 is a diagram conceptually showing the internal lottery table.

  The internal lottery table is used when an internal winning combination is drawn in the internal lottery process (FIG. 20, S8) of the main flowchart described later. The internal lottery table is a numerical value range or numerical value range that divides a predetermined range of random numbers from 0 to 65535 generated by the random number generator 69 and extracted by the sampling circuit 70 into respective winning numbers 1 to 6. Are stored as lower and upper limit values. Each winning number is associated with each internal winning combination, and numerical data is stored for each inserted number. Each winning number 1 to 6 is assigned a numerical range from 0 to 65535 numerical data or a lower limit value and an upper limit value defining this numerical range in pairs, and the extracted random number value belongs to the numerical range to which the extracted random number value belongs. The assigned winning number is selected.

  In the internal lottery table for the general gaming state shown in FIG. 5A, the winning number 1 corresponding to the small part of “Cherry” has a lottery value in the numerical value range 1 when the number of inserted coins is 1 and 2 respectively. When the number of inserted sheets is 3, lottery values in the numerical range 600 are assigned. The winning probability for 1 and 2 inserted sheets is 1/65536, and for 3 inserted sheets, the winning probability is 600/65536. In addition, the winning number 2 corresponding to the small part of “Bell” includes a lottery value in the numerical range 2000 when the number of inserted sheets is 1, and a lottery value in the numerical range 3000 when the number of inserted sheets is 2.

The winning number 6 corresponding to “BB1” includes a lottery value in the numerical range 10 when the number of inserted sheets is 1, and a lottery value and a inserted number of 3 in the numerical range 40 when the number of inserted sheets is 2. In the case of sheets, a numerical range of a lower limit value 1730 and an upper limit value 1821 is assigned. The winning probability when the inserted number is 1 is 10/65536, the winning probability when the inserted number is 2 is 40/65536, and the winning probability when the inserted number is 3 is 83/65536. When the random number extracted by the sampling circuit 70 is not included in the numerical range assigned to the winning numbers 1 to 6, “lost” is determined as the internal winning combination.

  In the internal lottery table for the RB gaming state shown in FIG. 5B, the lottery value in the numerical range 1 is assigned to the winning number 1 corresponding to the small part of “Cherry” when the number of inserted is one. If the extracted random number value belongs to this numerical range, the winning number 1 is selected. The winning probability of winning number 1 is 1/65536.

The BB1 stop table is a stop table that can stop-display the symbol combination “BB1”.

  FIG. 12 is a diagram conceptually showing the pull-in priority table.

  The pull-in priority table is used when determining a symbol to be prioritized in the reel stop control process (FIG. 20, S14) when a plurality of internal winning combinations are determined in the internal lottery process (FIG. 20, S8). The pull-in priority table stores data that associates the types of internal winning combinations with priorities. As shown in the figure, the internal winning combination “Replay” is assigned to priority 1, the internal winning roles “BB1” and “BB2” are assigned to priority 2, and the internal winning roles “Cherry” and “Bell” are assigned to priority 3. The priority ranking 4 is associated with the internal winning combination “watermelon”.

When the internal winning combination 1 is “00000001” representing “Cherry”, the numerical value “0” is set in bits 1 to 7 of the internal winning combination 2 storage area, and the numerical value “1” is set in bit 0. Set.

  FIG. 17 is a diagram conceptually showing the carryover combination storage area.

  In this carryover combination storage area, data of a carryover combination flag representing the type of the carryover combination determined in the internal lottery process (FIG. 20, S8) is stored. As shown in the figure, the carryover combination storage area is composed of 8 bits from bit 0 to bit 7, and a numerical value shown in the data column is set in each bit.

Set. When the carryover combination flag is not set, all bits 0 to 7 of the carryover combination storage area are set to a numerical value “0”.

  FIG. 18 conceptually shows the stop select counter storage area.

  In the stop select counter storage area, data representing the winning number determined mainly in the internal lottery process (FIG. 20, S8) in the reel stop initial setting process (FIG. 20, S9) is the value of the stop select counter. Stored as When the value of the stop select counter is the winning number 0 corresponding to “losing”, data representing the numerical value “0” is set in the stop select counter storage area. Winning number 1 corresponding to “Cherry”, winning number 2 corresponding to “Bell”, winning number 2 corresponding to “Watermelon”, winning number 4 corresponding to “Replay”, “BB2” In the case of each of the winning number 5 corresponding to “BB1” or the winning number 6 corresponding to “BB1”, the stop select counter storage area has the numerical values “1”, “2”, “3”, “4”, respectively , Data “5” or data “6” is set.

  The internal lottery result information storage area has the same configuration as the stop select counter storage area, but the contents of the stored data do not necessarily match. For example, when BB1 or BB2 is carried over, the contents of the stored data differ between the internal lottery result information storage area and the stop select counter storage area.

  FIG. 19 is a diagram conceptually illustrating a random value storage area.

  In this random value storage area, the random value extracted in the process of FIG. 20 and S6 is stored. As shown in the figure, in the random value storage area, data representing any random value from 0 to 65535 sampled by the sampling circuit 70 is set.

  Next, the control operation of the main CPU 64 of the main control board 61 will be described with reference to the main flowchart shown in FIG.

  First, the main CPU 64 performs an initialization process at the start of the game (see S1, FIG. 20). Specifically, the contents stored in the control RAM 66 are initialized, the communication data is initialized, and the like. Subsequently, an initialization storage area for the end of one game is set (S2).

  Next, the main CPU 64 clears the designated storage area in the control RAM 66 used in the previous game (S3), performs bonus operation monitoring processing described later (S4), and performs medal acceptance / start check processing described later. Perform (S5). Next, the main CPU 64 extracts the random number for lottery generated by the random number generator 69 by the sampling circuit 70, and stores the extracted random number value in the random value storage area (see FIG. 19) (S6). Next, the main CPU 64 performs a gaming state monitoring process which will be described later (S7), and subsequently performs an internal lottery process which will be described later (S8).

  Next, the main CPU 64 performs a reel stop initial setting process for determining a stop table used in the reel stop control process (S14) of the current unit game based on the lottery result in the internal lottery process of S8 (S9). . Subsequently, the main CPU 64 transmits a start command to the sub control board 62 side via the sub control unit communication port 79 (S10). The “start command” is a command including information on the gaming state identified in S7, the winning combination selected in the internal lottery process in S8, and the like.

  Subsequently, the main CPU 64 determines whether 4.1 seconds have elapsed since the start of the previous reel rotation (S11). When this determination is “NO”, waiting time digestion processing (S12) is performed until 4.1 seconds elapse. In the waiting time digestion process, a process of invalidating an input based on an operation of starting the game of the player (here, a process of waiting for the start of rotation of the reels 2 to 4) is performed.

  When 4.1 seconds have elapsed since the start of the previous reel rotation, the main CPU 64 requests the rotation start of all the reels 2 to 4 (S13), starts the rotation of all the reels 2 to 4, and subsequently, the reels described later. A stop control process is performed (S14). Next, the main CPU 64 performs a display combination search process described later (S15).

  Next, the main CPU 64 transmits a “display combination command” to the sub control board 62 side via the sub control unit communication port 79 (S16). The “display combination command” is a command including the type of combination of symbols that are actually displayed on the activated pay line. Next, the main CPU 64 performs medal payout processing (S17). In this process, if a game is played with credit, the number of stored coins displayed on the stored coin number display unit 16 is increased by the number of medals acquired by winning, and the medal insertion into the medal insertion slot 8 is performed. If the game is being played, the number of medals won by winning is paid out to the medal tray 37.

  After performing the processing of S17, the main CPU 64 updates the bonus end number counter based on the number of medals paid out (S18). That is, if the bonus end number counter is 1 or more, the counter is subtracted according to the number of medals paid out. Next, it is determined whether or not the BB operating flag or the RB operating flag is “ON” (S19). If any of the flags is “ON”, a bonus end check process described later is performed. (S20) If none of the flags is "ON", a bonus operation check process described later is performed (S21). After the process of S20, the game process returns to S2 and the next new unit game is started.

  Next, the bonus operation monitoring process performed in FIGS. 20 and S4 will be described with reference to FIG.

  In this bonus operation monitoring process, first, the main CPU 64 determines whether or not the BB operating flag is “ON” (see S31 in FIG. 21). If this determination is “YES”, the main CPU 64 determines whether or not the RB operating flag is “ON” (S32). If this determination is “NO”, the main CPU 64 performs RB operation processing based on the RB operation table (S33). If the determination in S31 is “NO”, the determination in S32 is “YES”, or after performing the process in S33, the bonus operation monitoring process ends.

  Next, with reference to FIG. 22, the medal acceptance / start check process performed in FIGS. 20 and S5 will be described.

  In this medal acceptance / start check process, first, the main CPU 64 determines whether or not the value of the automatic insertion counter is “0”, that is, the display unit is not “Replay” in the previous unit game and the automatic insertion of medals. Whether or not is performed is determined (see S41 in FIG. 22). If this determination is “YES”, the main CPU 64 performs a medal insertion permission process for permitting the medal insertion from the medal insertion slot 8 and the operation of the stored medal insertion buttons 26 to 28 (S42). On the other hand, if the determination is “NO”, the main CPU 64 updates the inserted number based on the automatic insertion counter (S43), and then sends a bet command to the sub control board 62 side via the sub control unit communication port 79. Transmit (S44). This bet command is a command including information on the number of medals automatically inserted. This is a command including information on the number of medals bet on a unit game by operating a medal insertion from the medal insertion slot 8 or a stored medal insertion button 26-28. After the processing of S42 or S44, the main CPU 64 determines whether or not the medal insertion is permitted, that is, whether or not the medal insertion from the medal insertion slot 8 or the operation of the stored medal insertion buttons 26 to 28 is permitted. (S45). If this determination is “YES”, the main CPU 64 checks the medal sensor 8S and the stored medal insertion switches 26S to 28S (S46). Subsequently, the medal insertion is detected by the medal sensor 8S, or it is determined whether or not the stored medal insertion switches 26S to 28S detect the operation of the stored medal insertion buttons 26 to 28 (S47). If this determination is “YES”, the main CPU 64 adds “1” to the value of the insertion number counter (S48). In this process, when the medal insertion from the medal insertion slot 8 is prohibited by the operation of the stored medal settlement button 29, the number of medals corresponding to the stored medal insertion buttons 26 to 28 detected in the number of credited medals. Is added. Subsequently, the bet command is transmitted to the sub control board 62 via the sub control unit communication port 79 (S49). This bet command is a command including information on the number of medals bet on a unit game by operating a medal insertion from the medal insertion slot 8 or a stored medal insertion button 26-28.

  Next, the main CPU 64 determines whether or not the RB operating flag is on (S50). If this determination is “NO”, whether or not the value of the insertion number counter is “3”. Is discriminated (S51). When the determination in S50 or S51 is “YES”, the main CPU 64 performs medal insertion prohibition processing (S52). In this process, when the insertion number counter is prohibited from being updated, and medals are subsequently inserted, the number of credit medals is updated by the number of inserted medals. When the determination in S45, S47, or S51 is “NO”, or after performing the process of S52, the main CPU 64 determines that the number of medals inserted, that is, the number of medals bet on a unit game is one or more. Whether the start switch is on, that is, whether there is an input from the start switch 30S based on the operation of the start lever 30 is determined. Is determined (S54). If the determination in S53 or S54 is “NO”, the process returns to S45 and the above-described process is repeated. On the other hand, when the determination is “YES”, the medal acceptance / start check process ends.

  Next, with reference to FIG. 23, the gaming state monitoring process performed in FIGS. 20 and S7 will be described.

  In this gaming state monitoring process, first, the main CPU 64 determines whether or not the RB operating flag is “ON” (see FIG. 23, S61). When this determination is “YES”, the main CPU 64 sets the identifier of the RB gaming state in a predetermined area of the control RAM 64 (S62), and when the determination is “NO”, the main CPU 64 sets the identifier of the general gaming state as a predetermined in the control RAM 64. Set to area. When the process of S62 or S63 is performed, the gaming state monitoring process ends.

  Next, the internal lottery process performed in FIGS. 20 and S8 will be described with reference to FIGS.

  In this internal lottery process, first, the main CPU 64 refers to the internal lottery table determination table (FIG. 8), and determines the type of lottery table and the number of lotteries based on the gaming state set in S7 above ( (See FIG. 24, S71). Subsequently, the main CPU 64 determines whether or not the value set in the carryover combination storage area (FIG. 17) is “0”, that is, whether or not there is no carryover combination (S72). If "", the number of lotteries is changed to "4" (S73). Next, the main CPU 64 sets the same value as the number of lotteries in the register as a winning number (S74). Accordingly, “6” is set in the general gaming state, “3” is set in the RB gaming state, and “4” is set in the internal winning state (carry-over state). Subsequently, it is determined whether or not the set winning number exceeds “4” (S75). If this determination is “YES”, the lower limit L corresponding to the winning number set in S74 is acquired with reference to the internal lottery table determined in S71 (S76). Subsequently, the lower limit L is subtracted from the random value R stored in the random value storage area (R−L), and it is determined whether the random value R is below the lower limit L (R <L) ( S77). If this determination is “NO”, the upper limit value U corresponding to the winning number is acquired (S78), and then the upper limit value U is subtracted from the random number value R stored in the random number storage area (R−). U), and it is determined whether or not the random number value R exceeds the upper limit value U (S79). When the determination in S79 is “NO”, since the random value R belongs to the numerical value range defined by the lower limit L and the upper limit U (L ≦ R ≦ U), the main CPU 64 determines the internal winning combination determination table (FIG. 10). ), The internal winning combination 1 and the internal winning combination 2 are determined based on the winning number (S80). Next, the main CPU 64 stores the logical sum of the internal winning combination 2 and the internal winning combination 2 storage area (FIG. 16) determined in S80 in the internal winning combination 2 storage area (S81), and the internal winning combination 2 storage area Set a bit according to the type of small role that was won. Subsequently, a logical product of the internal winning combination 1 determined in S80 and the bonus check data (00000110) is calculated, and a logical sum of this and the carryover combination storage area (FIG. 17) is stored in the carryover combination storage area (S82). ). Thereby, the determined BB1 or BB2 is stored in the carryover combination storage area. Next, the main CPU 64 stores the logical sum of the internal winning combination 1 and the carryover combination storage area in the internal winning combination 1 storage area (FIG. 15) (S83), and the bonus or replay won in the internal winning combination 1 storage area. Set a bit according.

  If the determination in S77 or S79 is “YES”, or after the process of S83, the main CPU 64 subtracts “1” from the number of lotteries (S84), returns the process to S74, and repeats the above process. If the determination in S75 is “NO”, the main CPU 64 obtains the random number value stored in the random value storage area in the register because the numerical range in the internal lottery table is defined by the lottery value (FIG. 25, FIG. 25). Refer to the internal lottery table and obtain the lottery value W based on the winning number and the number of inserted sheets (S86). Subsequently, the lottery value W is subtracted (R−W) from R stored in the register (S87). Next, the main CPU 64 determines whether or not a digit is obtained as a result of the subtraction (S88). If this determination is “NO”, the random value R exceeds the lottery value W to become the lottery value W. Since it does not belong, “1” is subtracted from the winning number (S89), and then “1” is subtracted from the number of lotteries (S90).

  Next, the main CPU 64 determines whether or not the number of lotteries is “0” (S91). If this determination is “NO”, the process returns to S86 and the above-described processes are repeated. When the determination in S88 or S91 is “YES” and the sizes of the random number R and the lottery value W are compared by the number of lotteries, the main CPU 64 refers to the internal lottery table and determines the internal number based on the winning number. The winning combination 1 and the internal winning combination 2 are determined (S92). Next, the main CPU 64 stores the logical sum of the determined internal winning combination 2 and the internal winning combination 2 storage area in the internal winning combination 2 storage area (S93). Next, the main CPU 64 calculates the logical product of the internal winning combination 1 and the bonus check data (00000110) and stores the logical sum of this and the carryover combination storage area in the carryover combination storage area (S94). Set the carryover combination in the carryover combination storage area. Next, the main CPU 64 stores the logical sum of the internal winning combination 1 and the carryover combination storage area in the internal winning combination 1 storage area (FIG. 15) (S95), and ends the internal lottery process.

  Next, the reel stop initial setting process performed in FIGS. 20 and S9 will be described with reference to FIG.

  In this reel stop initial setting process, first, the main CPU 64 determines whether or not the value set in the internal lottery result information storage area is “0”, that is, whether or not the internal winning combination is lost ( (See FIG. 26, S101). If this determination is “YES”, then the main CPU 64 determines whether the value set in the carryover combination storage area (FIG. 17) is “0”, that is, there is a bonus carried over. Is determined (S102). If the internal winning combination is not lost and the determination in S101 is “NO”, or if there is no bonus that the internal winning combination is lost and carried over and the determination in S102 is “YES”, the main CPU 64 determines the probability lottery. The winning number determined in the process (FIG. 20, S8) is stored in the stop select counter (S103). If there is a bonus that the internal winning combination is lost and carried over and the determination in S102 is “NO”, the main CPU 64 numbers the data in the carryover combination storage area, adds “3”, and the value obtained Is stored in the stop select counter (S104). That is, it is numbered 1 when bit 0 of the carryover combination storage area is on, 2 when bit 1 is on, 3 when bit 2 is on, and adds 3 to this numbered value. When bit 0 is on, 4 (replay), 5 (BB2) when bit 1 is on, and 6 (BB1) when bit 3 is on are stored in the stop select counter. To do. After the processing of S103 or S104, the main CPU 64 refers to the stop table determination table (FIG. 11), determines the stop table based on the winning number stored in the stop select counter, and determines the determined stop table in the control RAM 66. (S105), and the reel stop initial setting process is terminated.

  Next, the reel stop control process performed in FIGS. 20 and S14 will be described with reference to FIG.

  In this reel stop control process, first, the main CPU 64 determines whether or not any stop button 31 to 33 is pressed by rotating the reels 2 to 4 at a constant speed and an effective stop switch is turned “ON”. Is discriminated (see FIG. 27, S111). If this determination is “NO”, then the main CPU 64 determines whether or not the value of the automatic stop timer has become “0” without operating the stop buttons 31 to 33 (S112). If this determination is “NO”, the processing returns to S111 and the above-described processing is repeated. On the other hand, when the value of the automatic stop timer becomes “0” and the determination in S112 is “YES”, the main CPU 64 acquires information on the left reels 2 to 4 as a stop control target (S113). . When the effective stop switch is “ON” and the determination in S111 is “YES”, or when the processing of S113 is completed, the stop table determined in the reel stop initial setting processing (FIG. 20, S9) The number of sliding symbols is determined based on the internal winning combinations 1 and 2 determined in the internal lottery process (FIG. 20, S8) and the drawing priority table (FIG. 12) (S114). Next, the main CPU 64 determines the planned stop position of the symbol based on the number of sliding symbols determined in S114 and the current symbol position (S115), and the symbol moves to the determined planned stop position. The process shifts to a waiting stop position waiting state (S116). Next, the main CPU 64 transmits a reel stop command to the sub control board 62 side via the sub control unit communication port 79 (S117), and then determines whether or not there are any reels 2 to 4 that are currently rotating. (S118) If this determination is “YES”, the process returns to S111 and the above-described processes are repeated. On the other hand, when the determination is “NO”, the stop control process is terminated.

  Next, with reference to FIG. 28, the display combination retrieval process performed in FIGS. 20 and S15 will be described.

  In this display combination retrieval process, first, the main CPU 64 obtains the leading address of the symbol storage area (see S121 in FIG. 28). At each address in the symbol storage area, a symbol combination aligned with each winning line L1, L2A, L2B, L3A, L3B is set. Subsequently, the main CPU 64 determines whether or not the value of the effective line counter is “0” (S122). If this determination is “NO”, the display combination and the number of payouts are specified based on the symbol combination stored in the address and the symbol combination table (FIG. 7) (S123). Subsequently, “1” is subtracted from the value of the effective line counter (S124), and the next address of the symbol storage area is acquired. Thereafter, the processing returns to S122 and the above-described processing is repeated, and it is determined whether or not there is a symbol combination corresponding to the display combination for each activated pay line. When the determination in S122 is “YES”, the display combination and the number of payouts are specified for all the activated pay lines, and thus the display combination search process ends. In the display combination search process, when the specified display combination is different from the internal winning combination, or when the display combination is not included in the display combination determination data, the payout number display unit 20 and the liquid crystal display device 22 are displayed. An illegal error is displayed.

  Next, with reference to FIG. 29, the bonus end check process performed in FIG. 20 and S20 will be described.

  In the bonus end check process, first, the main CPU 64 determines whether or not the RB operating flag is “ON” (see S131 in FIG. 29). When this determination is “NO”, the main CPU 64 determines whether the value of the bonus end number counter (see FIG. 14) for counting 350 medals that can be paid out during the BB gaming state is “0”. Is determined (S132). When the determination in S131 is “YES”, the main CPU 64 determines whether or not a small combination winning is established, that is, whether or not a small combination is specified as a display combination in the display combination search process of FIG. (S133). If this determination is “YES”, the main CPU 64 determines whether or not the value of the bonus end number counter is “0” (S134), and if this determination is “YES”. RB end processing such as clearing the RB operating flag, the number of possible winnings and the number of possible games is performed (S135). If the determination in S132 is “YES”, or after performing the process of S135, the main CPU 64 performs a BB end time process such as clearing the BB operating flag and the bonus end number counter (S136).

  When the determination in S134 is “NO”, the main CPU 64 subtracts “1” from the number of possible winnings (S137), and then determines whether or not the number of possible winnings is “0” (S138). If this determination is “NO”, or if the determination in S133 is “NO”, the main CPU 64 subtracts “1” from the possible number of games (S139), and then the possible number of games is “0”. Whether or not (S140). When this determination or the determination in S138 is “YES”, the main CPU 64 performs the above-described RB end process (S141). If the determination in S132 or S140 is “NO”, or after performing the process of S136 or S141, the bonus end check process is terminated.

  Next, with reference to FIG. 30, the bonus operation check process performed in FIGS. 20 and S21 will be described.

  In this bonus operation check process, first, the main CPU 64 determines whether or not the display combination actually displayed on the reels 2 to 4 is “replay” (see FIG. 30, S151). If this determination is “YES”, the number of inserted sheets is copied to the automatic loading counter (S152). That is, numerical data representing the same number of medals as the number bet on the unit game is set to the value of the automatic insertion counter.

  When the determination in S151 is “NO”, the main CPU 64 determines whether or not the display combination is “BB1” or “BB2” (S153). When this determination is “YES”, the main CPU 64 performs the BB operation process based on the bonus operation table (S154), and then clears the carryover combination (S155). In the BB operation process, the main CPU 64 sets a BB operation flag and sets 350 in the bonus end number counter. If the determination in S153 is “NO”, or after the processing in S152 or S155 is performed, the bonus operation check processing is terminated.

  In the pachislot machine 1 according to the present embodiment, as described above, in the general gaming state internal lottery table shown in FIG. Is assigned a lottery value in a numerical range 600, a lottery value in a numerical range 5700 is assigned to a winning number 2 corresponding to a small part of “Bell”, and a winning number 5 corresponding to “BB2” is assigned a winning number. A numerical range of a lower limit value 579 and an upper limit value 661 partially overlapping with those of 1 and winning number 2 is assigned. In addition, the winning number 6 corresponding to “BB1” is assigned a numerical range of a lower limit value 1730 and an upper limit value 1812 that partially overlap with the case of the winning number 2.

  According to the pachislot machine 1 according to the present embodiment, the numerical range corresponding to the small winning combination of “cherry” or “watermelon” that is the predetermined winning combination and the small winning combination of “cherry” or “watermelon” are as described above. Since the numerical range corresponding to “BB1” or “BB2” which is a different specific winning combination is defined at least in part, the random number extracted by the random number extraction means is included in this overlapping numerical range. When belonging, a plurality of winning combinations of a predetermined winning combination corresponding to each numerical value range and a specific winning combination, Cherry or Bell and BB2, or Bell and BB1 are simultaneously determined. Therefore, it is possible to provide a new winning combination lottery system capable of determining a plurality of winning combinations at a time using only one random value and one internal lottery table. In addition, since it is not necessary to provide a plurality of internal lottery tables, it is not necessary to increase hardware resources that increase the memory capacity of the program ROM 65. In addition, since the value of the extracted random number is compared with both the upper limit value and the lower limit value only for a specific winning combination, the amount of data used for game processing can be reduced compared to the case where this determination is always performed. The required hardware resources can be suppressed.

  In addition, for the winning roles “BB2” and “BB1”, the numerical ranges are determined by the lower limit value and the upper limit value as shown in FIG. It can be distributed and provided irregularly. For this reason, even if the start operation by the start lever 30 is repeated at a certain timing due to fraud, the extracted random number value does not continue to be in the numerical value range corresponding to the winning combination related to winning. Therefore, the winning combination relating to the winning is not determined more than the originally scheduled probability, and the management of the amusement shop in which the pachislot machine 1 is installed is not deteriorated.

  As a result, by introducing a new lottery system for winning roles, it is possible to break down the fixed concept of players and create new fun, and to take effective measures against fraudulent acts. It is possible to provide a pachislot machine 1 that can satisfy both of the requirements. Moreover, since the random number extracted by the random number extraction means is compared with both the lower limit value and the upper limit value only for a specific winning combination, the amount of data used for game processing is reduced compared to the case where this determination is always performed. This can reduce the hardware resources required.

  Further, according to the pachislot machine 1 according to the present embodiment, in the internal lottery process (FIG. 20, S8), the small portion of “Cherry” or “Bell” and “BB2” or the small portion of “Bell” and “BB1” "" May be determined as an internal winning combination at the same time, so if a winning combination of "Cherry" or "Bell" is achieved, "BB2" or "BB1" You can have a sense of expectation that it was decided as an internal winner.

  In the description of the above embodiment, the assigned random number ranges partially overlap with the “Cherry” or “Bell” small part and “BB2”, and the “Bell” small part and “BB1”. Explained. However, the types of the combinations in which the assigned random number ranges partially overlap are arbitrary and may be changed as appropriate.

  In the description of the above embodiment, even when the random value R is equal to the lower limit value L or the upper limit value U (R = L or R = U) in the numerical range in the internal lottery process (FIG. 20, S8) The winning combination to which the numerical range is assigned is determined as the internal winning combination. However, only when the random value R exceeds the lower limit L of the numerical range (L <R) and falls below the upper limit (R <U), the winning combination to which the numerical range is assigned is determined as an internal winning combination. When the random number R is equal to the lower limit value or upper limit value of the numerical range (R = L or R = U), it is determined that the random value R does not belong to the numerical range, and the numerical range is assigned The winning combination may not be determined as an internal winning combination.

  In the above embodiment, the case where the gaming machine according to the present invention is applied to the pachislot machine 1 has been described. However, other gaming machines that determine an internal winning combination from a plurality of combinations based on detection of a start operation by the player The present invention can also be applied to. Even when the present invention is applied to such a gaming machine, the same effects as the above-described embodiment can be obtained.
