  Next, with reference to FIG. 2, the symbol sequence arranged on the reels 3L, 3C, 3R will be described.

  A reel sheet is mounted on the outer peripheral surface of each reel 3L, 3C, 3R, and a symbol row in which 21 types of symbols are arranged on the reel sheet is drawn. Specifically, red 7 (symbol 61), BAR (symbol 62), watermelon (symbol 63), bell (symbol 64), cherry (symbol 65), Replay (symbol 66), and blank (symbol 67) A symbol row composed of symbols is drawn. The blank is a symbol that is represented by a blank and is not directly related to the winning or bonus operation described below.

  Each reel 3L, 3C, 3R is rotationally driven so that the symbol row moves in the direction of the arrow in FIG. In addition, code numbers “0” to “20” for specifying the position of each symbol are determined in advance for each symbol and stored in a ROM 32 of a main control circuit 71 described later as a data table (a symbol arrangement table described later). Has been.

  The main control circuit 71 includes a microcomputer 30 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 30 includes a CPU 31 and ROM 32 and RAM 33 which are storage means.

  A clock pulse generation circuit 34, a frequency divider 35, a random number generator 36 and a sampling circuit 37 are connected to the CPU 31. The clock pulse generation circuit 34 and the frequency divider 35 generate a reference clock pulse. Based on the generated reference clock pulse, periodic interrupt processing (see FIG. 24) every 1.1173 msec, which will be described later, is performed. The random number generator 36 generates a certain range of random numbers (for example, 0 to 65535). The sampling circuit 37 extracts (samples) one random number value from the random number generated by the random number generator 36. By using the extracted random number value, an internal lottery process described later is performed, and predetermined information (for example, a winning number described later and an internal winning combination) is determined. As a means for random number sampling, random number sampling may be executed in the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, or can be left as a backup for the random number sampling operation.

  In the ROM 32 of the microcomputer 30, a program related to the processing of the CPU 31 (for example, see FIGS. 15 to 24 described later), various tables (for example, see FIGS. 4 to 11 described later), and the sub-control circuit 72. Various control commands (commands) are stored.

  The RAM 33 stores various information obtained by the processing of the CPU 31. For example, a plurality of areas (for example, see FIGS. 12 to 14 to be described later) are provided for storing various information for identifying internal winning combinations, carryover combinations, combinations of symbols displayed on active lines, and the like. . These pieces of information are transmitted to the sub-control circuit 72 by the above-described command.

  In the circuit of FIG. 3, as the main actuators whose operation is controlled by the control signal from the microcomputer 30, the bed lamps 9a, 9b, 9c, the information display unit 18, the hopper 40, the stepping motors 49L, 49C, 49R, and the like. is there.

  The hopper drive circuit 41 drives and controls the hopper 40. Thereby, the medal accommodated in the hopper 40 is paid out.

  The motor drive circuit 39 drives and controls the stepping motors 49L, 49C, 49R. As a result, the reels 3L, 3C, 3R are rotated or stopped.

  In the gaming machine 1, the driving pulses are output to the stepping motors 49L, 49C, and 49R through the motor driving circuit 39, and the rotation and stop of the reels 3L, 3C, and 3R are controlled by performing excitation. At this time, the number of output drive pulses is counted by the pulse counter of the RAM 33. In the gaming machine 1, when 16 drive pulses are output to the stepping motors 49L, 49C, 49R, the reels 3L, 3C, 3R rotate by a distance corresponding to one symbol. At this time, the number of symbols rotated is counted by the symbol counter in the RAM 33. That is, every time 16 pulses are counted by the pulse counter, the symbol counter is updated by one. Further, the symbol counter is sequentially updated with “0” to “20” as one cycle.

  Further, a reel index signal is detected from the reels 3L, 3C, and 3R every rotation and is output to the CPU 31 via the reel position detection circuit 50. The detection of the reel index signal clears the aforementioned pulse counter and symbol counter. Based on the symbol counter thus obtained and the symbol arrangement table described later, the symbol position and type within the range of one rotation of each reel 3L, 3C, 3R are determined. Here, the symbol position corresponding to the symbol counter is that of the symbol located on the center line 8c. For example, if the symbol counter of the left reel 3L is “20”, the symbol located on the center line 8c is a watermelon (symbol 63).

  Also, each switch and each circuit for generating an input signal that triggers outputting a control signal to each circuit and each actuator described above are connected to the input section of the microcomputer 30.

  The 1-bet switch 11S, the 2-bet switch 12S, and the maximum bet switch 13S detect the player's input operation on the 1-bet button 11, the 2-bet button 12, and the maximum bet button 13, respectively, and credited medals. Then, a signal for instructing insertion of one, two or three medals is output to the microcomputer 30.

  The C / P switch 14 </ b> S detects a player switching operation on the C / P button 14 and outputs a signal for switching the credit mode or the payout mode to the microcomputer 30. When the credit mode is switched to the payout mode, a signal for instructing the payout of medals credited to the gaming machine 1 is output to the microcomputer 30.

  The medal sensor 22S detects medals inserted into the medal insertion slot 22 by the player's insertion operation, and outputs a signal indicating that a medal has been inserted to the microcomputer 30.

  The reel position detection circuit 50 detects a pulse signal from the reel rotation sensor and generates a signal for detecting the position of the symbol on each reel 3L, 3C, 3R.

  The payout completion signal circuit 51 indicates that the payout of medals is completed when the number of medals detected by the medal detection unit 40S (that is, the number of medals paid out from the hopper 40) reaches the designated number. Generate a signal.

  The sub control circuit 72 performs various processes (such as determination and execution of effect contents) based on various commands (such as a start command described later) output from the main control circuit 71. The sub control circuit 72 does not input commands, information, or the like to the main control circuit 71, and communication is performed in one direction from the main control circuit 71 to the sub control circuit 72.

  The main actuators whose operation is controlled by a control signal from the sub control circuit 72 include the liquid crystal display device 5, the speakers 21L and 21R, the LED 101, and the lamp 102. The sub control circuit 72 determines and displays an image to be displayed on the liquid crystal display device 5 based on the determined content of the effect, determines and outputs the lighting pattern of the LED 101 and the lamp 102, and the effect sound and effect output from the speakers 21L and 21R. Determine and output sound.

  Further, the operation unit 17 and the volume control unit 103 are connected to the sub control circuit 72. The sub control circuit 72 displays an image corresponding to the information determined by the signal output from the operation unit 17 on the liquid crystal display device 5. Further, the sub control circuit 72 adjusts the volume output from the speakers 21L and 21R based on the signal output from the volume control unit 103.

  Next, the symbol arrangement table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG.

  The symbol arrangement table represents the arrangement of 21 symbols arranged on the reel sheet of each reel 3L, 3C, 3R as a data table as shown in FIG. That is, in the symbol arrangement table, red 7, BAR, watermelon, bell, cherry, Replay, and blank are defined in the same arrangement as in FIG. The symbol arrangement table is used to determine a symbol located on the center line 8c of each reel 3L, 3C, 3R based on the symbol counter described above.

  In the symbol arrangement table, code numbers “0” to “20” representing symbol positions and the respective positions where the reel index signal for detecting one rotation of the reel is output as a reference (that is, “0”) are displayed. The symbol type corresponding to the symbol position is defined. The code number representing the symbol position corresponds to the symbol counter value described above. Each symbol defined in the symbol arrangement table is represented by 1-byte data for identifying each symbol, for example, “00000001” for cherry. The data corresponding to each symbol is as shown in the figure.

  Next, an internal lottery table determination table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG. The internal lottery table determination table is used when an internal lottery table described later is determined in an internal lottery process described later.

  In the internal lottery table determination table, the type of the internal lottery table and the number of lotteries determined according to the gaming state are defined. In the general gaming state, the internal gaming state internal lottery table is determined, and the number of lotteries is determined to be six. However, the number of lotteries is changed to 4 when a carryover combination described later exists in the general gaming state. In the regular bonus (hereinafter abbreviated as “RB”) gaming state, the RB gaming state internal lottery table is determined, and the number of lotteries is determined to be three.

  Next, an internal lottery table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG. The internal lottery table is used when a winning number is determined in an internal lottery process described later.

  In the internal lottery table, a lottery value assigned to each winning number is defined for each inserted number. The winning number is information used when determining an internal winning combination based on an internal winning combination determining table described later. The lottery value represents the number of random values assigned to each winning number among all random number values (65536) generated in this table. Therefore, the larger the lottery value, the higher the probability that the winning number will be determined. The determination probability of each winning number is a value obtained by dividing the assigned lottery value by “65536” which is the number of all random numbers that may be generated.

  In the internal lottery table, the winning number is determined by searching to which lottery value the random number value extracted from the range of “0 to 65535” belongs. The search for which lottery value the extracted random value corresponds to is performed by sequentially subtracting the corresponding lottery value from the extracted random value in descending order of each winning number. Each time subtraction is performed, it is determined whether the subtraction result is positive or negative. If the result of the subtraction is negative, it is determined that the extracted random number value belongs to the lottery value of the winning number that has been searched, and the winning number is determined. The number of lotteries determined by the aforementioned internal lottery table determination table is equal to the number of times the winning number is searched in the internal lottery table. If no negative value is obtained as a result of searching for the number of lotteries, the winning number is determined to be 0.

  Specifically, it is performed as follows. First, when an arbitrary random number value is extracted from a random number range of “0 to 65535”, a lottery value with a winning number equal to the determined lottery number (for example, a winning number 6 if the number of lottery times is six) is acquired and extracted. The lottery value of the winning number is subtracted from the random number value. Next, 1 is subtracted from the number of lotteries, a lottery value with a winning number (for example, winning number 5) equal to the subtracted lottery number (for example, 5 times) is acquired, and the lottery value with the winning number is subtracted from the previous subtraction result. The Thereafter, similarly, the lottery value of the winning number is subtracted from the previous subtraction result until a negative value is obtained as the subtraction result. For example, when the number of inserted games in the general gaming state is 3, when the random value 150 is extracted, first, the lottery value 128 of the winning number 6 is acquired, and the lottery value 128 is subtracted from the random number 150. Since the subtraction result is a positive value, next, the lottery value 128 of the winning number 5 is acquired, and the lottery value 128 is subtracted from the previous subtraction result 22. Since the subtraction result is a negative value, the winning number 5 is determined.

  (1) of FIG. 6 shows the internal lottery table for general gaming states. In the general game state internal lottery table, lottery values are defined according to the number of inserted games. Specifically, lottery values corresponding to the winning numbers 1 to 6 are defined for every 1 to 3 inserted sheets.

  In the general game state internal lottery table, the larger the number of inserted cards, the larger the number of cards inserted, corresponding to each of Cherry, Bell, Watermelon, Big Bonus (hereinafter abbreviated as “BB”) 1 or BB2, which will be described later. The winning number decision probability is increasing step by step. Therefore, a lottery result that is advantageous to the player is obtained when the inserted number is larger.

  (2) of FIG. 6 shows the RB gaming state internal lottery table. In the RB gaming state, the maximum inserted number is defined as one, so in the RB gaming state internal lottery table, the lottery values corresponding to the winning numbers 1 to 3 are defined for only the inserted number 1. In the RB gaming state internal lottery table, a lottery value assigned to a winning number corresponding to a bell described later is extremely high.

  Next, an internal winning combination determination table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG. The internal winning combination determination table is used when determining an internal winning combination in an internal lottery process described later.

  In the internal winning combination determination table, an internal winning combination corresponding to each of the aforementioned winning numbers is defined. Corresponding to each of the winning numbers 0 to 6, lose, cherry, bell, watermelon, replay, BB2, and BB1 are defined. Each internal winning combination is represented by 1-byte data for identifying each, and the contents of the data are as shown in the figure. For example, cherry is represented by data “00000001”, and BB1 is represented by data “00100000”. That is, 1 is set in the bit corresponding to each internal winning combination.

  Thus, in the gaming machine 1, the winning number is determined by the internal lottery table, and the internal winning combination is determined by the internal winning combination determining table from the determined winning number. Although the winning number is determined in the internal lottery table, since the internal winning combination is also determined when the winning number is determined, it can be said that the determination of the winning number is the determination of the internal winning combination.

  Next, the effective line determination table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG. The effective line determination table is used to determine one winning line to be activated among the five winning lines 8a to 8e in the internal lottery process described later.

  In the effective line determination table, the types of effective lines determined according to the above-described winning numbers are defined. That is, the type of one winning line to be activated among the five winning lines 8a to 8e is determined according to the winning number determined for each unit game (that is, the internal winning combination). Yes.

  Specifically, if the winning number is 0 (that is, lost), 5 (that is, BB2), or 6 (that is, BB1), the center line 8c is determined as an effective line. If the winning number is 1 (that is, cherry), the cross-up line 8a is determined as an active line. If the winning number is 2 (that is, a bell), the top line 8b is determined as an active line. If the winning number is 3 (that is, watermelon), the bottom line 8d is determined as an active line. If the winning number is 4 (that is, replay), the cross-down line 8e is determined as an active line.

  Although not shown, the type of effective line is represented by 1-byte data for identifying each. For example, the center line 8c is represented by data “00000001”, the top line 8b is represented by data “00000010”, the bottom line 8d is represented by data “00000100”, and the cross-down line 8e is represented by “00001000”. The cross-up line 5a is represented by data “00010000”.

  Next, a symbol combination table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG. The symbol combination table is used when determining the display combination and the number of payouts in the display combination search process described later.

  In the symbol combination table, combinations of symbols composed of symbols displayed on the effective lines in the display windows 4L, 4C, and 4R, display combinations corresponding to the combinations, and payout numbers are defined. In addition, the display combination is represented by 1-byte data for identifying each, as in the above-described internal winning combination, and the contents of the data are as illustrated. For example, cherry is represented by data “00000001”. Although not shown, the symbols defined in the symbol combination table are represented by 1-byte data as in the symbols of the symbol arrangement table (see FIG. 4). For example, red 7 is represented by data “00100000”.

  When the cherry (symbol 65) is displayed on the effective line in the left display window 4L, the display combination is determined to be cherry regardless of the types of symbols displayed in the remaining display windows 4C and 4R. If the inserted number is 1 or 2, the payout number is determined to be 15, and if the input number is 3, the payout number is determined to be 4. In addition, as described above, when the internal winning combination is cherry, the cross-up line 8a is determined as an effective line, so basically the cherry (symbol 65) is the lower part in the left display window 4L. The display combination is determined to be cherry.

  By displaying three bells (symbol 64) side by side along the active line, the display combination is determined to be a bell. If the inserted number is 1 or 2, the payout number is determined to be 15, and if the input number is 3, the payout number is determined to be 10. Further, as described above, when the internal winning combination is the bell, the top line 8b is determined as the effective line, so basically three bells (symbol 64) are arranged along the top line 8b. The display combination is determined to be a bell.

  By displaying three watermelons (symbol 63) side by side along the active line, the display combination is determined to be watermelon. In addition, the payout number is determined to be 8 in common with all the input numbers. Further, as described above, when the internal winning combination is watermelon, the bottom line 8d is determined as the effective line, so basically three watermelons (symbol 63) are arranged along the bottom line 8d. The display combination is determined to be watermelon.

  By displaying three replays (symbol 66) along the active line, the display combination is determined to be replay. When replay is determined, replay is performed in the next unit game. That is, the same number of medals as the number of coins inserted in the unit game in which replay is established are automatically inserted in the next unit game without being based on the player's insertion operation. Thereby, the player can perform the next unit game without consuming medals. Further, as described above, when the internal winning combination is replay, the cross-down line 8e is determined as the effective line, so basically, the Replay (symbol 66) is 3 along the cross-down line 8e. By displaying them side by side, the display combination is determined to be replay.

  By displaying three BARs (symbol 62) along the active line, the display combination is determined as BB2. Further, three reds 7 (symbol 61) are displayed side by side along the active line, whereby the display combination is determined as BB1. When BB1 or BB2 is determined, a BB operating flag, which will be described later, is updated to ON, and the operation of BB is started. Further, as described above, when the internal winning combination is BB1 or BB2, the center line 8c is determined as the effective line, so basically, red 7 (symbol 61) or BAR (symbol 62) is displayed. By displaying the three side by side along the center line 8c, the display combination is determined as BB1 or BB2. BB1 or BB2 has red 7 (symbol 61) or BAR (symbol 62) lined up along the position of the effective line corresponding to the above-mentioned cherry, bell, or watermelon because of the drawing priority order described later. It may be determined by being displayed.

  Further, when a symbol combination other than the symbol combinations related to cherry, bell, watermelon, replay, BB2, and BB1 is displayed, the display combination is determined to be lost.

  Next, the configuration of the pull-in priority table will be described with reference to FIG. The pull-in priority order table is used when determining the number of sliding symbols together with the stop table described above in the reel stop control process described later.

  The number of sliding symbols indicates the number of symbols that will move from the stop operation position until the corresponding reels 3L, 3C, 3R stop rotating after the signal is output by the stop switch 7S.

  Here, in the gaming machine 1, basically, after the signal is output by the stop switch 7S, the rotation of the reels 3L, 3C, 3R is controlled to be stopped within 190 msec. (That is, 0 frame, 1 frame, 2 frames, 3 frames, or 4 frames). For this reason, for example, when the red 7 (symbol 61) with the code number “0” is positioned on the center line 8c during the rotation of the right reel 3R, the pressing operation of the right stop button 7R is detected by the stop switch 7S. In this case, the rotation of the right reel 3R can be stopped (so-called pull-in) so that the watermelon (symbol 63) with the code number “4” is displayed on the center line 8c.

  In addition, in the symbol row of each reel 3L, 3C, 3R, the symbol (design 64) and the replay (design 66) that are arranged for each of the four frames, which are the maximum number of sliding symbols, are either Even if the stop operation is performed at the symbol position, each symbol can be surely drawn on the effective line. On the other hand, in the symbol row of each reel 3L, 3C, 3R, the symbols that are not arranged for each of the above-described maximum four-frame range, ie, red 7 (symbol 61), BAR (symbol 62). ), Watermelon (symbol 63), and cherry (symbol 65) cannot be drawn on the active line unless a stop operation is performed at a specific symbol position within the range of 4 frames from each symbol. (So-called “spillover” occurs).

  The pull-in priority table is basically used when two or more types of internal winning combinations are determined. The drawing priority order table defines the order of symbols to be preferentially displayed on the active line within the range of the maximum number of sliding frames. Specifically, the pull-in priority is determined in the order of “Replay”, “BB1 or BB2”, “Bell or Cherry”, and “Watermelon”. As a result, when two types of internal winning combinations are determined, basically, a combination of symbols related to one is preferentially displayed based on the drawing priority order.

  For example, when a watermelon is selected when BB1 is carried over, when a signal is output by the stop switch 7S, the watermelon (symbol 63) and red 7 are within the range of the maximum number of sliding frames (for example, 4 frames). In the case where both (symbol 61) exist, the number of sliding frames is determined so that red 7 (symbol 61) is preferentially displayed on the active line (that is, red 7 is drawn). The

  Next, a bonus operation time table stored in the ROM 32 of the main control circuit 71 will be described with reference to FIG. The bonus operation time table is used when the operation of BB or RB is started in a bonus operation check process described later.

  In the bonus operation time table, information stored in a predetermined area of the RAM 33 is defined according to the type of bonus.

  When the BB is operated, the BB operating flag in the RAM 33 is turned on, and 350 is stored in the bonus end number counter. The bonus end number counter is information for counting the number of medals to be paid out during the BB operation, and the corresponding payout number is subtracted every time a winning is established. When the bonus end number counter is updated to 0, the operation of BB ends.

  Further, when the RB is operated, the RB operating flag in the RAM 33 is turned on, 12 is stored in the possible game number counter, and 8 is stored in the possible winning number counter. The game possible number counter is information for counting the number of unit games performed during the RB operation, and a value of 1 is subtracted every time a unit game is performed. The winning possible number counter is information for counting the number of times winning is achieved during RB operation, and a value of 1 is subtracted when the display combination is watermelon, bell, or cherry. When the game possible number counter or the winning possible number counter is updated to 0, the operation of the RB ends.

  Next, the configuration of the internal winning combination storing area of the RAM 33 of the main control circuit 71 will be described with reference to FIG.

  When the internal winning combination is determined by the internal winning combination determination table, the determined internal winning combination is stored (stored) in the internal winning combination storing area. The internal winning combination storage area consists of 1 byte, bit 0 corresponds to cherry, bit 1 corresponds to bell, bit 2 corresponds to watermelon, bit 3 corresponds to replay, bit 4 corresponds to BB2 Bit 5 corresponds to BB1. That is, 1 is set in the bit string corresponding to the determined internal winning combination. In case of loss, each bit is 0. When two or more types of internal winning combinations are determined, 1 is set in the bit string corresponding to each.

  The RAM 33 is provided with a display combination storage area for storing information on the determined display combination. This display combination storage area has the same configuration as the internal winning combination storage area described above.

  Next, the configuration of the carryover combination storage area of the RAM 33 of the main control circuit 71 will be described with reference to FIG.

  When BB1 or BB2 is determined as an internal winning combination by the internal winning combination determination table, the determined BB1 or BB2 is stored in this carryover combination storing area. The carryover combination storage area consists of 1 byte, bit 4 corresponds to BB2, and bit 5 corresponds to BB1. When the operation of BB is started, the data in the carryover combination storage area is cleared. That is, in the gaming machine 1, when the above-described BB1 or BB2 is determined, a combination of symbols related to these is displayed and the information is stored until the operation of the BB is started. (Called so-called carry-over). Since the carryover combination is determined based on the internal winning combination, it can be said to be a subordinate concept of the internal winning combination.

  Next, the configuration of the symbol storage area of the RAM 33 of the main control circuit 71 will be described with reference to FIG. The display combination is determined based on the symbol storage area and the symbol combination table described above.

  In the symbol storage area, data for identifying symbols displayed in the display windows 4L, 4C, 4R (that is, winning lines 8a to 8e) as a result of the reels 3L, 3C, 3R being stopped are stored. Is done. The symbol storage area is provided for each of the five winning lines 8a to 8e.

  When the reels 3L, 3C, 3R are stopped, the symbols displayed on the effective line determined by the above-mentioned effective line determination table based on the above-mentioned symbol counter and the symbol arrangement table (see FIG. 4). The type is specified, and data indicating the type of the specified symbol is stored in the symbol storage area.

  For example, when the effective line is determined to be the center line 8c, the type of the symbol displayed on the center line 8c is specified, and data indicating the specified symbol type is stored in the symbol storage area corresponding to the center line 8c. Stored. In the symbol storage area corresponding to the center line 8c, data for identifying the symbol displayed at the middle position in the left display window 4L and the symbol displayed at the middle position in the central display window 4C are displayed. Data for identifying and data for identifying the symbol displayed at the middle position in the right display window 4R are stored.

  The data stored in each symbol storage area consists of 1 byte and corresponds to the symbol data defined in the symbol arrangement table described above. That is, bit 0 corresponds to cherry, bit 1 corresponds to bell, bit 2 corresponds to watermelon, bit 3 corresponds to replay, bit 4 corresponds to BAR, bit 5 corresponds to red 7 .

  Next, the control operation of the CPU 31 of the main control circuit 71 will be described with reference to the flowcharts shown in FIGS.

  First, a reset interrupt process performed by the CPU 31 of the main control circuit 71 will be described with reference to FIG. The CPU 31 turns on the power and applies a voltage to the reset terminal to generate a reset interrupt, and sequentially performs the reset interrupt processing stored in the ROM 32 based on the occurrence of the reset interrupt. It is configured.

  When the power is turned on, first, the CPU 31 performs an initialization process (step S1). In this initialization process, a process of restoring registers and addresses based on information stored in the RAM 33 when the power is shut off is performed.

  Next, the CPU 31 sets (stores) an initialization storage area for the end of one game in a register (step S2). Next, the CPU 31 clears the designated storage area in the one-game-end initialization storage area (step S3). Thereby, for example, data stored in the random value storage area, the internal winning combination storage area, or the symbol storage area is cleared.

  Next, the CPU 31 performs a bonus operation monitoring process which will be described later with reference to FIG. 16 (step S4). In this bonus operation monitoring process, when the RB is not operating during the BB operation, the RB operation process is performed.

  Next, the CPU 31 performs medal insertion / start check processing described later with reference to FIG. 17 (step S5). In the medal insertion / start check process, the insertion number counter is updated by checking the medal sensor 22S and the input of the start switch 6S is checked.

  Next, the CPU 31 performs a random value extraction process (step S6). Specifically, the CPU 31 uses the random number generator 36 and the sampling circuit 37 to extract lottery random values used in an internal lottery process described later.

  Next, the CPU 31 performs a gaming state monitoring process which will be described later with reference to FIG. 18 (step S7). In this gaming state monitoring process, a process of storing the gaming state identifier in the current unit game in the RAM 33 is performed.

  Next, the CPU 31 performs an internal lottery process which will be described later with reference to FIG. 19 (step S8). In this internal lottery process, determination of an internal winning combination based on the aforementioned internal lottery table (see FIG. 6) and internal winning combination determination table (see FIG. 7), determination of one winning line to be activated in the current unit game, etc. Is performed.

  Next, the CPU 31 transmits a start command to the sub control circuit 72 (step S9). The start command includes information such as an internal winning combination and a gaming state.

  Next, the CPU 31 determines whether or not 4.1 seconds have elapsed since the start of the previous reel rotation (step S10). When it is determined that 4.1 seconds have not elapsed, the CPU 31 digests the waiting time (step S11). Specifically, the CPU 31 performs a standby process without performing the subsequent processes until 4.1 seconds elapse.

  When it is determined in step S10 that 4.1 seconds have elapsed, or after performing the process of step S11, the CPU 31 requests rotation start of all reels (step S12). Specifically, the CPU 31 performs processing such as turning on a rotation start request flag. When the start of rotation of all reels is requested, the reels 3L, 3C, and 3R are started to rotate in the reel control process (step S163) of the interrupt process described later with reference to FIG.

  Next, the CPU 31 performs a reel stop control process which will be described later with reference to FIG. 20 (step S13). In this reel stop control process, a process such as determination of the number of sliding frames based on the input of the stop switch 7S, stop of rotation of the reels based on the determined number of sliding frames is performed.

  Next, the CPU 31 performs a display combination search process which will be described later with reference to FIG. 21 (step S14). In the display combination search process, processing such as determination of the display combination and the number of payouts is performed.

  Next, the CPU 31 transmits a display combination command to the sub control circuit 72 (step S15). The display combination command includes information such as the established display combination.

  Next, the CPU 31 performs medal payout processing (step S16). Specifically, the CPU 31 pays out medals by driving control of the hopper 40, updating of a credit counter, or the like based on the payout number counter updated in the process of step S14.

  Next, the CPU 31 updates the bonus end number counter based on the payout number counter (step S17). Specifically, if the value of the bonus end number counter is 1 or more, the CPU 31 subtracts the counter according to the payout number.

  Next, the CPU 31 determines whether or not at least one of the RB operating flag and the BB operating flag is on (step S18). When it is determined that at least one of the RB operating flag and the BB operating flag is on, the CPU 31 performs a bonus end check process described later with reference to FIG. 23 (step S19). In this bonus end check process, a BB end process and an RB end process are performed based on a bonus end number counter, a winning possible number counter, or a possible gaming number counter.

  When the CPU 31 determines in step S18 that neither the RB operating flag nor the BB operating flag is on, or after performing the processing of step S19, the bonus operation described later with reference to FIG. Check processing is performed (step S20). In this bonus operation check process, when the display combination is BB1 or BB2, a BB operation process is performed.

  As described above, the CPU 31 executes the process from step S2 to step S20 as the process in the unit game. When the process in step S20 is completed, the CPU 31 proceeds to the process in step S2 to execute the process in the next unit game.

  Next, the bonus operation monitoring process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the BB operating flag is on (step S41). When determining that the BB operating flag is not on, the CPU 31 ends the bonus operation monitoring process and proceeds to step S5 in FIG.

  When determining that the BB operating flag is on in step S41, the CPU 31 determines whether or not the RB operating flag is on (step S42). If the CPU 31 determines that the RB operating flag is on, it ends the bonus operation monitoring process and proceeds to step S5 in FIG.

  When the CPU 31 determines in step S42 that the RB operating flag is not ON, the CPU 31 performs RB operating processing based on the bonus operating table (see FIG. 11) (step S43). Specifically, the CPU 31 turns on the RB operating flag, stores 12 in the possible game number counter, and stores 8 in the possible game number counter. When this process ends, the bonus operation monitoring process ends, and the process proceeds to step S5 in FIG. As described above, in the gaming machine 1, even when the operation of the RB is completed while the operation of the BB is being performed, the operation of the RB is continuously performed by immediately starting the operation of the RB in the next unit game. It is configured to be performed.

  Next, the medal insertion / start check process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the automatic insertion counter is 0 (step S51). When determining that the automatic insertion counter is 0, the CPU 31 permits medal reception (step S52). The automatic insertion counter is information for identifying whether or not a replay has been established in the previous unit game.

  When determining that the automatic insertion counter is not 0 in step S51, the CPU 31 updates the insertion number counter based on the automatic insertion counter (step S53). The inserted number counter is information for specifying the inserted number, and the upper limit is 3. Next, the CPU 31 transmits a bet command to the sub control circuit 72 (step S54). The bet command includes information on the number of inserted coins.

  After the process of step S54 or after the process of step S52, the CPU 31 determines whether or not the medal acceptance is permitted (step S55). When determining that the medal acceptance is permitted, the CPU 31 performs a check process for the medal sensor 22S and the bet switches 11S, 12S, and 13S (step S56).

  Next, the CPU 31 determines whether or not it is a charging process (step S57). Specifically, the CPU 31 determines whether or not there is an input from the medal sensor 22S or the bet switches 11S, 12S, and 13S by the player's insertion operation.

  If the CPU 31 determines in step S57 that it is the insertion process, it updates the insertion number counter (step S58). In this process, when it is prohibited to update the inserted number counter, the CPU 31 updates the credit counter instead of the inserted number counter. The credit counter is information for specifying the number of credited medals, and the upper limit value is 50.

  Next, the CPU 31 transmits a bet command to the sub control circuit 72 (step S59). Next, the CPU 31 stores 1 in the effective line counter (step S60). The valid line counter is information for specifying the number of valid lines. Even if the value of the insertion number counter is updated after this processing, 1 is always stored in the valid line counter regardless of the value of the insertion number counter.

  After the process of step S62 or the process of step S61, the CPU 31 determines whether or not the RB operating flag is on (step S61). When determining that the RB operation flag is not on, the CPU 31 determines whether or not the insertion number counter is 3 (step S62).

  When the CPU 31 determines in step S64 that the insertion number counter is 3, or when it is determined in step S63 that the RB operation flag is on, the insertion number counter is prohibited from being updated (step S63).

  After performing the process of step S63, the CPU 31 determines that the medal acceptance is not permitted in step S55, determines that it is not the insertion process in step S57, or determines that the insertion number counter is not 3 in step S62. When it is determined, it is determined whether or not the insertion number counter is 1 or more (step S64). When the CPU 31 determines that the input number counter is not 1 or more, the CPU 31 proceeds to step S55.

  When the CPU 31 determines in step S64 that the insertion number counter is 1 or more, it determines whether or not the start switch 6S is on (step S65). When the CPU 31 determines that the start switch 6S is not on, the CPU 31 proceeds to step S55.

  When the CPU 31 determines in step S65 that the start switch 6S is on, it prohibits medal acceptance (step S66). When this process ends, the medal insertion / start check process ends, and the process proceeds to step S6 in FIG.

  Next, the gaming state monitoring process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the RB operation flag is on (step S81). When determining that the RB operating flag is on, the CPU 31 stores the identifier of the RB gaming state in a predetermined area of the RAM 33 (step S82). When this process ends, the gaming state monitoring process ends, and the process proceeds to step S8 in FIG.

  When the CPU 31 determines in step S81 that the RB operating flag is not on, it stores the general gaming state identifier in a predetermined area of the RAM 33 (step S83). When this process ends, the gaming state monitoring process ends, and the process proceeds to step S8 in FIG.

  Next, the internal lottery process will be described with reference to FIG.

  First, the CPU 31 refers to the aforementioned gaming state identifier, and determines the type of the internal lottery table and the number of lotteries based on the internal lottery table determination table (see FIG. 5) (step S91).

  Next, the CPU 31 determines whether or not the data in the carryover combination storage area (see FIG. 13) of the RAM 33 is 0 (that is, whether there is a carryover combination) (step S92). When the CPU 31 determines that the data in the carryover combination storage area is not 0 (that is, there is a carryover combination), the CPU 31 changes the number of lotteries to 4 (step S93). That is, when there is a carryover combination, BB1 or BB2 is not determined.

  When the CPU 31 determines in step S92 that the data in the carryover combination storage area is 0, or after performing the process of step S93, the CPU 31 sets the same value as the number of lotteries in the register as the winning number (step S94).

  Next, the CPU 31 refers to the internal lottery table (see FIG. 6), and acquires a lottery value based on the winning number and the number of inserted sheets (step S95). Next, the CPU 31 subtracts the lottery value acquired from the random value (step S96).

  Next, the CPU 31 determines whether or not a digit has been performed (step S97). Specifically, the CPU 31 determines whether or not the obtained value is negative as a result of subtracting the acquired lottery value from the random value. When the CPU 31 determines that the digit is not set, the CPU 31 subtracts 1 from the winning number set in the register (step S98). Next, the CPU 31 subtracts 1 from the number of lotteries (step S99).

  Next, the CPU 31 determines whether or not the number of lotteries is 0 (step S100). When the CPU 31 determines that the number of lotteries is not 0, the CPU 31 proceeds to step S95.

  When the CPU 31 determines that a digit has been made in step S97, or when it is determined in step S100 that the number of lotteries is 0 (in this case, the winning number is 0), it is set in the register. The winning number is stored in the RAM 33, and the internal winning combination is determined based on the winning number stored in the RAM 33 with reference to the internal winning combination determination table (see FIG. 7) (step S101).

  Next, the CPU 31 calculates the logical product of the internal winning combination and the bonus check data, and stores the logical sum of the internal winning combination storage area in the carryover combination storage area (step S102). The bonus check data is 1-byte data represented by “00110000”. Thereby, carry over of BB1 or BB2 is performed.

  Next, the CPU 31 stores the logical sum of the internal winning combination and the carryover combination storage area in the internal winning combination storage area (see FIG. 12) (step S103). Based on the data in the internal winning combination storing area, the number of sliding frames, which will be described later, is determined.

  Next, the CPU 31 refers to the effective line determination table (see FIG. 8) and determines an effective line based on the winning number stored in the RAM 33 (step S104). For example, if the winning number is 5 (that is, BB2), the center line 8c is determined as an active line. Further, when the CPU 31 determines an effective line, it stores the identifier of the determined effective line in a predetermined area of the RAM 33. When this process ends, the internal lottery process ends, and the process proceeds to step S9 in FIG.

  Next, the reel stop control process will be described with reference to FIG.

  First, the CPU 31 determines whether or not a valid stop button has been pressed (step S111). Specifically, it is determined whether or not an effective stop button pressing operation is detected by the stop switch 7S. If the CPU 31 determines in step S111 that a valid stop button has not been pressed, it repeats the process of step S111.

  When the CPU 31 determines in step S111 that a valid stop button has been pressed, the internal winning combination (more specifically, data stored in the internal winning combination storing area), the determined effective line, and the pull-in The number of sliding frames is determined based on the priority table (see FIG. 10) (step S112).

  Specifically, when the stop switch 7S is turned on, the CPU 31 determines that the maximum number of sliding frames (4 frames) is within the range based on the symbol counter and the symbol arrangement table (see FIG. 4). A search is made as to whether or not a symbol position capable of displaying a symbol related to the internal winning combination exists on the determined active line. If the symbol position exists as a result of the search, the difference up to the symbol position is determined as the number of sliding frames.

  For example, when performing the stop control of the left reel 3L, if the internal winning combination is BB2 and the symbol counter is 11, the BAR (symbol 62) within the range of 4 frames from the replay of the code number 11 (symbol 66). ) Is searched for on the active line (that is, the center line 8c) (see FIG. 2). As a result of the search, since BAR (symbol 62) exists at the position of code number 13, 2 which is the difference from code number 11 to code number 13 is determined as the number of sliding frames.

  Also, for example, when a watermelon is won when BB2 is carried over, the symbol position that can display the watermelon (symbol 63) and the symbol that can display the BAR (symbol 62) within the range of the maximum number of sliding symbols. In the case where both of the positions exist, the number of sliding frames is determined so that the BAR (symbol 62) is preferentially displayed on the active line (that is, the center line 8c).

  Next, the CPU 31 determines a planned stop position based on the determined number of sliding symbols and the current symbol position (step S113). For example, if the number of sliding symbols is 2 and the current symbol position (that is, the symbol position on the center line 8c corresponding to the symbol counter) is the code number 11, the CPU 31 determines the code number 13 as the scheduled stop position. To do. Further, in this process, the CPU 31 turns on the scheduled stop position wait state flag, thereby in the reel control process (step S163) of the interrupt process with a period of 1.1173 ms which will be described later with reference to FIG. A process of stopping after waiting for the rotation of the reel is performed until the stop position is reached.

  Next, the CPU 31 transmits a reel stop command to the sub control circuit 72 (step S114). The reel stop command includes information such as the type of the stopped reel.

  Next, the CPU 31 stores the identifier of the symbol displayed on the effective line determined this time in the symbol storage area (step S115). Specifically, based on the type of the stop button that has been pressed, the symbol counter, and the symbol arrangement table, the symbol displayed on the activated line determined this time is specified, and data for identifying the symbol is stored in the symbol storage area ( (See FIG. 14). For example, if the left reel 3L is stopped and the determined effective line is the center line 8c, the symbol displayed at the middle position in the left display window 4L is specified, and data for identifying the symbol is specified as the center line 8c. Is stored in the symbol storage area corresponding to. For example, if the symbol displayed at the middle position in the left display window 4L is BAR (symbol 62), “00010000” is stored in the symbol storage area corresponding to the center line 8c.

  Next, the CPU 31 determines whether or not there is a rotating reel (step S116). When the CPU 31 determines that there is a rotating reel, the CPU 31 proceeds to step S111 and similarly performs the above-described processing for the remaining rotating reels. If the CPU 31 determines that there is no rotating reel, it ends the reel stop control process and proceeds to step S14 in FIG.

  Next, the display combination search process will be described with reference to FIG.

  First, the CPU 31 sets the head address of the symbol storage area corresponding to the determined effective line, and acquires the effective line counter (step S121). For example, if the determined effective line is the center line 8c, the head address of the symbol storage area corresponding to the center line 8c is set. Also, 1 is stored in the valid line counter.

  Next, the CPU 31 determines whether or not the valid line counter is 0 (step S122). When the CPU 31 determines that the effective line counter is 0 (that is, the search for the effective line is completed), the CPU 31 ends the display combination search process and proceeds to step S15 in FIG.

  When the CPU 31 determines in step S122 that the effective line counter is not 0, it is based on the symbol combination and symbol combination table (see FIG. 9) stored in the symbol storage area (see FIG. 14) set in step S121. The display combination is determined (step S123).

  Next, the CPU 31 refers to the symbol combination table (see FIG. 9), determines the payout number based on the determined display combination and the input number counter, and updates the payout number counter (step S124). Next, the CPU 31 subtracts 1 from the effective line counter (step S125). When this process ends, the process moves to step S122.

  Next, the bonus operation check process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the display combination is BB1 or BB2 (step S131). When the CPU 31 determines that the display combination is either BB1 or BB2, the CPU 31 performs BB operation processing based on the bonus operation table (see FIG. 11) (step S132). Specifically, the CPU 31 turns on the BB operating flag and stores 350 in the bonus end number counter.

  Next, the CPU 31 clears the carryover combination storage area (step S133). When this process ends, the bonus operation check process ends, and the process proceeds to step S2 in FIG.

  When determining that the display combination is neither BB1 nor BB2 in step S131, the CPU 31 determines whether the display combination is replay (step S134). If the CPU 31 determines that the display combination is not replay, it ends the bonus operation check process and proceeds to step S2 in FIG.

  If the CPU 31 determines in step S134 that the display combination is replay, it copies the insertion number counter to the automatic insertion number counter (step S135). As a result, the same value as the insertion number counter is stored in the automatic insertion number counter. When this process ends, the bonus operation check process ends, and the process proceeds to step S2 in FIG.

  Next, the bonus end check process will be described with reference to FIG.

  First, the CPU 31 determines whether or not a winning has been established (step S141). When determining that a winning is achieved in step S141, the CPU 31 determines whether or not the bonus end number counter is 0 (step S142).

  If the CPU 31 determines in step S142 that the bonus end number counter is 0, the CPU 31 performs RB end time processing (step S143). Specifically, the CPU 31 clears the RB operating flag and clears the winning possible number counter and the possible gaming number counter.

  Next, the CPU 31 performs processing at the end of BB (step S144). Specifically, the CPU 31 clears the BB operating flag and the bonus end number counter. When this process ends, the bonus end check process ends, and the process proceeds to step S20 in FIG.

  When the CPU 31 determines in step S142 that the bonus end number counter is not 0, the CPU 31 subtracts 1 from the winning possible number counter (step S145). Next, the CPU 31 determines whether or not the winning possible number counter is 0 (step S146).

  When the CPU 31 determines in step S146 that the winable number counter is not 0, or when it is determined in step S141 that no win has been established, the CPU 31 subtracts 1 from the possible game number counter (step S147). Next, the CPU 31 determines whether or not the game possible number counter is 0 (step S148).

  If the CPU 31 determines in step S148 that the possible game number counter is not 0, the bonus end check process ends, and the process proceeds to step S20 in FIG.

  When the CPU 31 determines that the possible game number counter is 0 in step S148, or when it is determined that the winning number counter is 0 in step S146, the CPU 31 performs the RB end process in the same manner as the process in step S143. This is performed (step S149). When this process ends, the bonus end check process ends, and the process proceeds to step S20 in FIG.

  Next, with reference to FIG. 24, an interrupt process with a cycle of 1.1173 ms, which is performed under the control of the CPU 31 of the main control circuit 71, will be described.

  First, the CPU 31 saves the register (step S161). Next, the CPU 31 performs input port check processing (step S162). Specifically, the CPU 31 checks the input of signals from each switch.

  Next, the CPU 31 performs a reel control process (step S163). Specifically, the CPU 31 starts and stops the rotation of the reels 3L, 3C, 3R in response to a reel rotation start request or the like.

  Next, the CPU 31 performs a lamp / 7SEG driving process (step S164). Specifically, the CPU 31 performs processing such as lighting of the bet lamps 9a, 9b, and 9c based on the insertion number counter, and displaying on the information display unit 18 the number of payouts when winning is established based on the number of payouts.

  Next, the CPU 31 restores the register (step S165). When this process ends, the interrupt process with a cycle of 1.1173 ms ends.

  As described above, in the gaming machine 1 of the present embodiment, the type of one winning line to be activated among the five winning lines 8a to 8e is determined based on the internal winning combination determined for each unit game. As a result of the rotation of the reels 3L, 3C, 3R being stopped, the display combination is searched based on the combination of one symbol displayed on the determined effective line.

  As a result, the type of one effective line for which the display combination is searched can be varied depending on the internal winning combination. Therefore, it is possible to prevent the active line type from being fixed to a specific type in each unit game. As a result, it is possible to prevent each unit game from becoming monotonous and to improve the interest of the game.

  In addition, since the type of one active line to be determined is determined in advance depending on the type of the internal winning combination, basically a display combination of a predetermined type is established according to each winning line 8a to 8e. Can be made. For example, if the internal winning combination is a watermelon, the effective line is determined to be the bottom line 8d. Therefore, the display combination watermelon is established by displaying three watermelons (symbol 63) side by side on the bottom line 8d. It will be. Therefore, when the player pays attention to the combination of symbols displayed on a specific winning line (for example, the above-described bottom line 8d), the display combination corresponding to the winning line (for example, the above-mentioned watermelon) is established. The presence or absence of the game can be easily understood by the player. As a result, as compared with a conventional gaming machine having a plurality of effective lines for searching for display combinations, it is not known in which line the display combination desired by the player is established. It is possible to reduce the burden when the player grasps whether or not is established.

  In addition, the player may predict which type of internal winning combination is determined by observing whether or not a symbol related to the corresponding internal winning combination is displayed on each of the winning lines 8a to 8e. It becomes possible, and the interest of the game can be improved. For example, if a watermelon (symbol 63) is drawn and displayed on the bottom line 8d when the first stop operation is performed, it may be determined that the watermelon is determined as an internal winning combination. It is also possible to make predictions.

  Moreover, in the gaming machine 1 of the present embodiment, as described above, since the symbols related to the internal winning combination are drawn within the range of 4 frames which is the maximum number of sliding symbols, the symbols may be missed depending on the arrangement of the symbols. There are no internal winning combinations (Bell, Replay) and internal winning combinations (Watermelon, Cherry, BB1, BB2) that can be missed. For example, in the above-described effective line determination table, the top line 8b that connects the upper position in the display window is defined in correspondence with the internal winning combination that cannot be missed. On the other hand, the bottom line 8d connecting the lower positions in the display window is defined corresponding to the watermelon that is an internal winning combination that may be missed. Here, the player sees the bottom line 8d connecting the lower position in each display window more easily than the top line 8b connecting the upper position in each display window. The range that can be used is large. Therefore, it is possible to determine an effective line that is suitable for the player to carry out the main winning combination for the internal winning combination that may be missed (that is, the internal winning combination that requires the main pressing).

  In addition, in a gaming machine that employs a plurality of active lines as in the prior art, it is necessary to search for a display combination for the combination of symbols displayed on each of the plurality of active lines, resulting in a processing delay. However, in the gaming machine 1 of the present embodiment, only one effective line is determined, and there is no need to search for a display combination for each of a plurality of effective lines. The burden on the processing can be reduced.

  Although the present embodiment has been described above, the present invention is not limited to this.

  In the present embodiment, the combination defined in the above-mentioned effective line determination table (see FIG. 8) is applied as the combination of the internal winning combination type and the corresponding effective line type. However, the present invention is not limited to this. The combination of the internal winning combination type and the corresponding active line type can be arbitrarily changed.

  In the present embodiment, a center line 8c, a top line 8b, a bottom line 8d, a cross-down line 8e, a cross-up line are connected as a plurality of lines connecting a plurality of symbol display positions determined in advance for each of the plurality of display units. Although 8a is applied, the present invention is not limited to this, and other lines may be applied. For example, a line connecting the upper position in the left display window 4L, the middle position in the center display window 4C, and the upper position in the right display window 4R can be applied.

  In addition, the symbol display means, the start operation detection means, the symbol variation means, the internal winning combination determination means, the stop operation detection means, the stop control means, the line determination means, the combination identification means, the discrimination means, and the privilege provision that constitute the gaming machine The specific configurations of the means, the plurality of lines, one line, etc. are not limited to the elements of the present embodiment described above, and can be arbitrarily changed.

  Also, the device configuration shown in FIGS. 1 and 2, the circuit configuration shown in FIG. 3 and its peripheral devices, the table configurations shown in FIGS. 4 to 11, and the RAMs shown in FIGS. 12 to 14 applied in this embodiment. The storage area configuration, the flowchart configurations shown in FIGS. 15 to 24, and the like can be arbitrarily changed or modified without departing from the spirit of the present invention.

  The present invention can also be applied to other gaming machines such as slot machines, pachinko machines, arrange balls, sparrow balls, video slots, video poker, etc., in addition to the pachislot machines as in the present embodiment. Furthermore, a game can be executed by applying the present invention to a game program in which the above-described operation in the slot machine is simulated for a home game machine. In that case, a CD-ROM, FD (flexible disk), or any other recording medium can be used as a recording medium for recording the game program.
