TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gaming machine in which an effect based on a false internal winning mode different from an internal winning mode determined by lottery is performed with a predetermined probability.
[0002]
[Prior art]
Conventionally, there is a slot machine as such a gaming machine.
[0003]
In the slot machine game, when a medal is inserted and the start lever is operated, the internal winning mode is determined by a lottery by the winning mode determining means of the main control circuit, and a plurality of reels having a plurality of symbols drawn on an outer peripheral surface are formed. Start rotation. Thereafter, when the stop button is operated and the reels stop in a predetermined symbol combination according to the internal winning mode, a winning is generated. When the determined internal prize mode is the bonus prize mode, the internal winning flag is carried over to the next and subsequent games even if the stopped reel is not a predetermined symbol combination. Therefore, if the reels stop in the symbol combination corresponding to the bonus winning mode in the game after the next time, a bonus winning occurs.
[0004]
In addition, information on the internal winning mode determined by the main control circuit is falsely imitated by another internal winning mode with a predetermined probability, and is transmitted to the sub-control circuit that controls the effect. The sub-control circuit controls the production of a series of games based on the received information. For example, when the received internal prize mode is the bonus prize mode, the liquid crystal display device provided on the front surface of the housing displays a notification of the bonus internal prize, or the bonus confirmation lamp provided on the front panel lights up. Or
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional slot machine, a false internal prize mode different from the internal prize mode determined by the prize mode determining means is transmitted from the main control circuit to the sub-control circuit with a very small predetermined probability. Therefore, a game effect may be performed based on an internal winning mode different from the actually determined internal winning mode. Therefore, when the bonus prize mode is falsely transmitted to the sub control circuit, an effect of notifying the bonus internal prize is performed, but a phenomenon occurs that the bonus prize mode does not occur forever, and a player occurs. Is very unpleasant.
[0006]
[Means for Solving the Problems]
The present invention has been made in order to solve such a problem, and has a prize mode determining means for determining an internal prize mode by lottery, and a game process for performing a game process in the internal prize mode determined by the prize mode determining means. Means, false winning prize mode determining means for faking the internal winning mode determined by the winning mode determining means to another internal winning mode with a predetermined probability, and a game based on the internal winning mode determined by the false winning mode determining means. A gaming machine configured to include an effect means for performing an effect, a privilege game performing means for performing a privilege game advantageous to a player when an effect based on a false specific internal winning mode is performed by the effect means. It is characterized by having.
[0007]
According to such a configuration, when an effect based on the specific false internal winning mode determined by the false winning mode determining unit is performed by the directing unit, a privilege game advantageous to the player, for example, the winning mode determining process An assist time game for guiding the occurrence of the winning in the internal winning mode determined by the means is performed. Therefore, the player can compensate for the unpleasantness that the specific prize mode is not generated even though the effect based on the specific internal prize mode is performed by the benefit of the privilege game.
[0008]
Further, the present invention is a bonus winning mode in which a specific internal winning mode is carried over to the next game by the winning mode determining means when no winning occurs in the current game, and Means, if the winning flag of the bonus winning mode is generated by the false winning mode determining means in the previous game, and if the winning flag of the bonus winning mode is not carried over by the false winning mode determining means in the current game, It is characterized in that it is determined that the effect performed by the effect means in the previous game is an effect based on a false bonus winning mode.
[0009]
According to such a configuration, in the game following the game in which the effect based on the bonus winning mode is performed, if the internal winning flag of the bonus winning mode is not carried over, it is determined that a false bonus winning effect has been performed. , A bonus game is executed.
[0010]
Further, the present invention is characterized in that an effect based on a specific internal winning mode is an effect that is not performed based on another internal winning mode.
[0011]
According to such a configuration, the effect based on the specific internal winning mode is performed, thereby suggesting to the player that the internal winning mode is determined to be the specific winning mode. Therefore, when an effect other than the effect based on the specific internal prize mode is performed, the player does not recognize that the internal prize mode is fixed to the specific internal prize mode.

Occurs at a higher probability than during a general game.
[0027]
{Circle around (2)} When three combinations of re-game symbols are lined up on the activated pay line in the B / B regular game, two coins are paid out.
[0028]
(3) Thereafter, the process proceeds to a bonus game which is an RB game in which a plurality of jack games can be performed. The bonus game in the BB game is also terminated when, for example, a jackpot prize is generated eight times, or when the total number of jackpot games executed during the bonus game reaches, for example, twelve.
[0029]
{Circle around (4)} When the above-mentioned bonus game is over, the general game during B / B described in (1) above is performed again, and the symbol combination described in (2) above occurs in the general game during B / B. Then, the bonus game described in the above (3) is further performed. The BB game is a repetition of a set of a series of BB regular games and bonus games shown in the above (1) to (3), and if this set is performed a predetermined number of times, for example, twice, B・ The B game is over. However, during this BB game, the total number of games in the above-mentioned (1) and (2) general games during the BB, ie, the total number of games excluding the number of jack games in the bonus game of (3) above Is exceeded a predetermined number of times, for example, 30 times, the BB game ends.
[0030]
FIG. 2 and FIG. 3 show a circuit configuration of a main control board 61 and a sub control board 62 for controlling the game processing operation of the slot machine 1 described above.
[0031]
The control unit in the main control board 61 shown in FIG. 2 is mainly composed of a microcomputer (hereinafter, referred to as a microcomputer) 63, and further includes a circuit for random number sampling. The microcomputer 63 includes a main CPU (central processing unit) 64 for performing control operations according to a preset program, a program ROM (read only memory) 65 as a program storage means, and a control RAM with a backup function (random access memory). (Memory) 66.
[0032]
The main CPU 64 includes a clock pulse generating circuit 67 for generating a reference clock pulse, a frequency divider 68, a random number generator 69 for generating a random number within a certain range, and a random number sampling circuit 70 for specifying one of the generated random numbers. It is connected. Further, an I / O port (input / output port) 71 for transmitting / receiving signals to / from a peripheral device (actuator) described later is connected. The storage section of the program ROM 65 is divided so as to store a probability lottery table, a symbol table, a winning symbol combination table, a pseudo-winning flag lottery table, a sequence program, and the like. The microcomputer 63 constitutes a winning mode determining means for determining an internal winning mode by lottery. Further, the microcomputer 63 constitutes a game processing means for performing a game process in the internal winning mode determined by the winning mode determining means. Further, the microcomputer 63 also constitutes a false prize mode determining means that falsifies the internal prize mode determined by the prize mode determining means with another predetermined internal prize mode.
[0033]
The main actuators whose operations are controlled by control signals from the microcomputer 63 include a stepping motor 45 for rotating and driving the reels 2, 3, and 4; various lamps (game operation display lamps 13 to 15, a start lamp 17, a WIN lamp). 21, an insert lamp 23), various display units (chance LEDs 9 to 12, a stored number display unit 16, a bonus count display unit 20, a winning award number display unit 22), and a hopper 72 for storing medals. These are driven by a motor drive circuit 73, each lamp drive circuit 74, each display section 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.
[0034]
The main input signal generating means for generating an input signal necessary for the microcomputer 63 to generate a control signal includes an inserted medal sensor 8S for detecting a medal inserted from the medal insertion slot 8, and an operation of the start lever 30. There is a start switch 30S for detecting a stored medal, the stored medal insertion switches 27 and 28, and a stored medal settlement switch 29 described above. Further, there is provided a reel position detecting circuit 77 which receives the output pulse signal from the photo sensor and detects the rotational position of each of the reels 2, 3, and 4. The photo sensor is included in the drive mechanism of each of the reels 2 to 4, and is not shown in FIG.
[0035]
After the rotation of the reels 2 to 4 is started, the reel position detection circuit 77 counts the number of drive pulses supplied to each of the stepping motors 45, and writes the counted value in a predetermined area of the control RAM 66. Therefore, in the control RAM 66, a count value corresponding to the rotation position within the range of one rotation is stored for each of the reels 2 to 4. The photo sensor generates a reset pulse every time each of the reels 2 to 4 makes one rotation. This reset pulse is given to the main CPU 64 via the reel position detection circuit 77, and the count value of the drive pulse counted in the control RAM 66 is cleared to "0". By this clearing process, a shift generated between the movement display of each symbol and the rotation of each stepping motor 45 is eliminated for each rotation.
[0036]
Further, the input signal generating means includes a reel stop signal circuit 78 for generating a signal for stopping a corresponding reel when the stop button 31, 32, 33 is pressed, and a medal for counting the number of medals paid out from the hopper 72. There is a detection unit 72S and a payout completion signal generation circuit (not shown). These are also connected to the main CPU 64 via the I / O port 71. The payout completion signal generation circuit, when the medal count value actually paid out input from the medal detection unit 72S reaches the payout number data represented by the count signal input from the display unit drive circuit 75, the payout completion signal generation circuit Generate a signal to detect completion.
[0037]
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. 3 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 transmitted from the sub control unit communication port 79 to the main control unit communication port 88 includes a command type whose control type is represented by a 7-bit length, and a content of the command having a maximum length of 24 bits. And the parameters that are represented.
[0038]
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 which performs a control operation according to a preset program, a program ROM 83 as a program storage means, and a control RAM 84 with a backup function. A clock pulse generating circuit 85 for generating a reference clock pulse and a frequency divider 86 are also connected to the sub CPU 82, and further, an I / O for transmitting and receiving signals to and from the main controller communication port 88 and an actuator described later. The / O port 87 is connected.
[0039]
As an actuator whose operation is controlled by a control signal from the microcomputer 81, a stepping motor 97 for rotating and driving the effect rotation reel 25, reel back lamps 47a, 47b, 47c built in each of the reels 2 to 4, the AT determination lamp 18, There is a bonus confirmation lamp 19 and a dot matrix display device 24. These are driven by a motor drive circuit 92, a lamp drive circuit 89, and an LED drive circuit 90, respectively. These drive circuits 89, 90, 92 are connected to the CPU 82 via the I / O port 87 of the microcomputer 81.
[0040]
As an input signal generating means for generating an input signal necessary for the microcomputer 81 to generate a control signal, there is a reel position detecting circuit 93 for detecting a rotational position of the effect rotating reel 25. The reel position detection circuit 93 counts the number of drive pulses supplied to the stepping motor 97 after the rotation of the effect spinning reel 25 is started. The count value is written in a predetermined area of the control RAM 84, and the CPU 82 grasps the rotational position of the effect rotating reel 25 from the count value. The microcomputer 81 fetches game start information such as the game state and the type of the winning flag at that time from the main control board 61 via the main control unit communication port 88, and based on the fetched game start information, the reel back lamps 47a, 47b, 47c. And the effect pattern displayed by the dot matrix display device 24 and the effect rotating reel 25 are selected.
[0041]
A sound source IC 91 is connected to the I / O port 87. A sound ROM 94 in which sound data is stored is connected to the sound source IC 91, and the sound source IC 91 emits various sounds from the speakers 96 via the power amplifier 95 under the control of the microcomputer 81. That is, the microcomputer 81 controls the sound source IC 91 and the power amplifier 95 in accordance with an instruction input from the main control board 61 via the main control unit communication port 88, and outputs a medal shooting sound, a start lever operation sound, and a stop button operation sound. , A game effect sound such as a sound effect during a bonus, a sound effect produced in response to a game process, a production sound, and the like are output from the speakers 96 and 96.
[0042]
The microcomputer 81 constitutes an effect means for effecting a game based on the internal winning mode determined by the false winning mode determining means constituted by the microcomputer 63 of the main control board 61. Further, the microcomputer 81 constitutes a privilege game executing means for performing a privilege game advantageous to a player when an effect based on a specific false internal winning mode is performed by the effect means. In the present embodiment, the specific internal prize mode is set to the BB and RB bonus prize modes in which the prize flag is carried over to the next game by the prize mode determining means when no prize is generated in the current game. Have been. In addition, as a privilege game, an assist time (AT) game for guiding the occurrence of the internal winning mode determined by the winning mode determining means is performed. The AT game is a game that guides the stopping order of the reels 2 to 4 that generate a winning according to the lighting order of the reel back lamps 47a, 47b, 47c. The microcomputer 81 determines that the winning flag of the bonus winning mode is generated by the false winning mode determining means in the previous game, and that the winning flag of the bonus winning mode is not carried over to the current game by the false winning mode determining means. It is determined that the bonus effect performed in the previous game was an effect based on a false bonus winning mode.
[0043]
FIG. 4 conceptually shows a probability lottery table stored in the program ROM 65 of the main control board 61 and used during a general game. This probability lottery table is used to divide the random numbers extracted by the sampling circuit 70 during the general game into the respective winning modes, and stores data for partitioning a certain range of random numbers generated by the random number generator 69 into the respective winning modes. I remember. In the drawing, a1 to a3, b1 to b3, c1 to c3, d1 to d3, e1 to e3, f1 to f3, and g1 to g3 are preset numerical data, and random numbers extracted by the sampling circuit 70 are It is used when partitioning into a winning mode. This data uses a combination of numerical values of “a1 to g1” when the number of inserted medals is one, “a2 to g2” for two, and “a3 to g3” for three. Can be
[0044]
These numerical values are usually set in a magnitude relationship of “a <b <c <d <e <f <g”. If the extracted random number value is less than d, a small hit prize (small hit) is obtained. If it is less than "cherry", a request flag is set. If it is more than a and less than b, it is a request flag per "group". If it is more than b and less than c, it is a request flag per bell. Has a request flag for a "mountain" hit. If the extracted random number value is equal to or more than d and less than e, a "re-game" request flag is set. If the extracted random number value is equal to or more than e and less than f, a medium hit prize (medium hit) is set and a request flag is set for "RB". If the extracted random number value is equal to or more than f and less than g, a large hit prize ( A big hit) and a request flag for “BB” is set. On the other hand, if the value is equal to or larger than g, no winning is achieved. In other words, the winning mode is determined by which numerical range one sampled random number belongs to, and is represented by the hit request flag.
[0045]
The “BB” or “RB” bonus hit request flag is carried over to subsequent games even if no bonus prize is generated in the flagged game. The carried-over bonus request flag is cleared when a symbol combination of “BB” or “RB” is stopped and displayed on the activated pay line and a bonus win actually occurs. Flags other than the bonus hit request flag are valid only in the flagged game, are cleared at the end of the game, and are not carried over after the next game.
[0046]
FIG. 5 conceptually shows a pseudo-winning flag lottery table stored in the program ROM 65 of the main control board 61. This pseudo winning flag lottery table is used for the false winning mode determining means to false the internal winning mode determined by the probability lottery table shown in FIG. 4 to another internal winning mode with a predetermined probability. The internal winning mode determined by the false winning mode determining means is represented as a pseudo winning flag. The pseudo-winning flag is transmitted to the microcomputer 81 of the sub-control board 62 which is the effect means, instead of the actual winning flag determined by the winning mode determining means.
[0047]
In this table, an actual internal winning flag whose type is indicated as a code in the row direction of the information column is assigned to any pseudo winning flag whose type is indicated as a code in the column direction. In this assignment, random numbers extracted from the random number range of 0 to 16777215 are divided into 18 sections each including a numerical value “1” and a numerical value “A (= 16777199)” arranged in the column direction for each actual internal winning flag. This is performed by determining which one of the above is applicable. Winning flags “losing”, “cherry”, “group”, “bell”, “mountain”, “replay”, “RB” indicated by codes 00H, 01H, 02H, 04H, 08H, 10H, 20H, and 40H , And "BB" are selected during a general game. However, the “re-game” of the code 10H is also selected when the RB is won in the BB regular game. In addition, the winning flags “Cherry”, “Group”, “Bell”, “Mountain”, and “Replay” indicated by the codes 21H, 22H, 24H, 28H, and 30H are selected during the RB. “Cherry”, “group”, “bell”, “mountain”, and “replay” indicated by the codes 41H, 42H, 44H, 48H, and 50H are selected to be inside the BB. For example, when the actual internal winning flag determined with reference to the probability lottery table shown in FIG. 4 described above is “Bell” of the code 04H, the extracted random number corresponds to the section “A”, and is set as the pseudo-winning flag. The probability that “Bell” will be drawn as it is is extremely high, 16777199/16777216, and the probability that the other 17 pseudo-winning flags will be drawn is set to extremely low, 1/171677216, respectively. That is, the false prize mode determining means falsifies the internal prize mode determined by the prize mode determining means to another prize mode with a probability of 17/16777216.
[0048]
According to the table, when the internal winning flags actually determined are 00H to 10H and the pseudo winning flags 20H to 50H are drawn in the section surrounded by the thick line, the pseudo winning flags are false. The bonus prize winning mode is shown.
[0049]
In the program ROM 65 of the main control board 61, a symbol table (not shown) is stored in addition to the probability lottery table and the pseudo-winning flag lottery table. The symbol table associates the rotation positions of the reels 2 to 4 with the symbols, and represents a symbol array by symbols. The symbol table includes a code number sequentially assigned to each reel at a constant rotation pitch based on a rotation position at which a reset pulse is generated, and a symbol code indicating a symbol provided corresponding to each code number. Are stored.
[0050]
The above-mentioned program ROM 65 stores a winning symbol combination table (not shown). The winning symbol combination table stores a symbol code of each winning symbol combination shown in the payout table, a symbol code of a symbol combination constituting a “reach eye”, a winning determination code representing each winning, a winning medal payout number, and the like. Have been. Here, the reach eye is a symbol that indicates that the occurrence of the "BB" or "RB" game is close to the player when the "BB" or "RB" request flag is already set. It is a combination. The winning symbol combination table is referred to at the time of stop control of the first reel 2, the second reel 3, and the third reel 4, and at the time of performing a winning confirmation after stopping all the reels. Further, a sequence program for executing a game in the slot machine 1 is stored in the program ROM 65.
[0051]
FIG. 6 is a diagram schematically showing an effect pattern selection table for a general game stored in the program ROM 83 of the sub control board 62. As described above, in the present embodiment, a character or the like having a motif of Saiyuki is displayed and an effect is performed.
[0052]
The sub CPU 82 draws an effect pattern based on the pseudo-winning flag transmitted from the main control board 61 with reference to the effect pattern selection table. The effect pattern is pattern No. Fifteen types of "0" to "14" are set. Production pattern No. 0 is "no effect" in which no effect is performed. The effect pattern No. 1 is an effect “Hackai” in which a character pattern of Inokachi Kamen drawn on the outer periphery of the effect rotation reel 25 is displayed. Reference numeral 2 denotes an effect “reverse reverse” in which the character design of Inokachi Kai is displayed after the effect spinning reel 25 rotates in a direction opposite to the normal rotation. Similarly, the effect pattern No. 3 is an effect “Sagojo” in which a character design of Sagojo drawn on the outer circumference of the effect rotating reel 25 is displayed. Reference numeral 4 denotes an effect "reverse sagojo" in which the effect spinning reel 25 rotates in the reverse direction to display the character design of Sagojo. The effect pattern No. 5 is an effect “hand” in which a pattern of the hand of Sanzo Hoshi drawn on the outer periphery of the effect rotating reel 25 is displayed, and the effect pattern No. 5 is displayed. Reference numeral 6 denotes an effect “hand → sheet of cloth” in which once the hand is displayed, the effect spinning reel 25 rotates again, and finally a pictographic design of sheet of cloth is displayed. The effect pattern No. No. 7 is an effect “Tenji”, in which a pictographic design “Tianji” is displayed, and effect pattern No. 7 is displayed. Reference numeral 8 denotes an effect “reverse sheeting” in which the effect rotating reel 25 rotates in the reverse direction to display a pattern on the sheeting.
[0053]
The effect pattern No. Reference numeral 9 denotes an effect “Dot cherry” in which a pattern of cherry is displayed by the dot matrix display device 24, and an effect pattern N0.10 is an effect “Dot bell” in which a symbol of a bell is displayed by the dot matrix display device 24. . Similarly, the effect pattern No. 11 is an effect “Dot mountain” in which a mountain pattern is displayed, and an effect pattern No. No. 12 is an effect “Dot Replay” in which an English letter “R” is displayed, and effect pattern No. 12 is displayed. 13 is an effect “Dot7” in which the number “7” is displayed.
[0054]
In addition, the effect pattern NO. Reference numeral 14 denotes an effect "reel off" in which the normally-lit reel back lamps 47a, 47b, 47c are turned off during a general game.
[0055]
According to the table, for example, when the pseudo winning flag is “Cherry”, the effect pattern No. 0 “No effect” is selected with a probability of 384/32768, and the effect pattern No. 2 "Reverse crack" or production pattern no. 4 “Reverse Sagojo” has a probability of 8000/32768, respectively. 9 "Dot cherry" is selected with a probability of 16384/32768.
[0056]
Also, according to the table, the effect pattern No. 6 “Hand → India”, production pattern No. 7 “Tianji”, production pattern No. 8 “Reverse sheeting”, production pattern No. The effect of 13 "Dot7" is selected only for the bonus winning mode of "RB" or "BB", and the pseudo winning flags of other winning modes are not selected. In other words, these effect patterns are bonus internal winning notification effects in which the player can recognize that the bonus winning mode has been internally won when the effect is performed.
[0057]
Next, an operation of the slot machine 1 controlled by the above-described control circuit will be described.
[0058]
7 to 9 are flowcharts showing the outline of the game processing controlled by the main CPU 64 of the main control board 61.
[0059]
First, an initialization process at the time of starting a game is performed (see FIG. 7, step 101). In this initialization processing, a predetermined area of the control RAM 66 is cleared, and communication data between the main control board 61 and the sub control board 62 is initialized. Next, the main CPU 64 performs a RAM clear process at the end of the game to erase the data stored in the control RAM 66 at the end of the previous game (step 102).
[0060]
Subsequently, as a result of the previous game, the CPU 64 determines whether or not a replay (replay) has occurred and a medal automatic insertion request has been issued (step 103). If there is this automatic insertion request, game medals corresponding to the insertion request are automatically inserted (step 104). On the other hand, if there is no automatic insertion request, then a medal is inserted into the medal insertion slot 8 by the player and a detection signal is input from the inserted medal sensor 8S or the stored medal insertion switches 27 and 28 are operated. It waits for the input signal to be input (step 105). Up to three medals can be inserted during a general game, and one medal can be inserted in a bonus game during a BB game or an RB game.
[0061]
Next, it is determined whether or not a start signal has been input from the start switch 30S by operating the start lever 30 (step 106). If this determination is "Yes", it is next determined whether 4.1 seconds have elapsed since the previous game (step 107). If 4.1 seconds have not elapsed, a wait time command is transmitted to the sub-control board 62 via the sub-control unit communication port 79 (step 108), and the wait function operates to allow 4.1 seconds. The game start waiting time until the time elapses is consumed (step 109). If the operation of the start lever 30 is performed before the elapse of the 4.1 seconds, the reels 96 and 96 emit reel non-rotatable sounds, and the player is notified that the weight function has been activated.
[0062]
When 4.1 seconds have elapsed since the last game, a random number for lottery generated by the random number generator 69 is extracted by the sampling circuit 70 (step 110), and thereafter, the above-mentioned 4.1 seconds is counted. One game monitoring timer is set (step 111). Next, a probability lottery process is performed based on the random numbers extracted in step 110 (see FIG. 8, step 112). This probability lottery process is performed by determining to which winning group the one random number value specified by the sampling circuit 70 belongs in the probability lottery table (see FIG. 4). At this time, the probability lottery data a1 to g1, a2 to g2, or a3 to g3 shown in each row of the probability lottery table in FIG. 4 is used according to the number of medals inserted into the machine. Subsequently, based on the internal winning flag determined by the probability lottery process, the pseudo winning flag lottery is referred to the pseudo winning flag lottery table (see FIG. 5) (step 113).
[0063]
Next, reel rotation processing is performed (step 114), and subsequently, start command transmission processing is performed (step 115). In the reel rotation process, first, a predetermined area of the control RAM 66 in which the rotation positions of the reels 2 to 4 are written is initialized by the main CPU 64 at the start of reel rotation, and subsequently, the reels 2 to 4 are rotated by the stepping motor 45. Driven. In the start command transmission process, a start command is transmitted to the sub-control board 62 via the sub-control unit communication port 79 based on a start signal input from the start switch 30S to the main CPU 64. The start command includes a 16-bit parameter indicating the type of the pseudo winning flag generated in step 113 and the game state.
[0064]
Next, it is determined whether any of the stop buttons 31 to 33 has been turned on (step 116). If the ON operation has not been performed, it is determined whether or not the automatic stop timer has reached 0 (step 117). The automatic stop timer is for automatically stopping each of the reels 2 to 4 after a lapse of a predetermined time when the stop buttons 31 to 33 are not operated for a predetermined time.
[0065]
When any one of the stop buttons 31 to 33 is turned on or the automatic stop timer reaches 0, the number of frames of the symbol drawn on the activated pay line, that is, the number of sliding frames is determined (step). 118). The number of sliding frames is determined from the game state, the winning request, the number of controlling frames, the symbol position, and the like. If the number of frames from the activated winning line to the winning symbol is within the range of the number of controlling frames, it is determined as the number of sliding frames. You. Next, the number of sliding frames is stored in a predetermined area of the control RAM 66. Thereafter, a stop request flag for the first stop reel is set, and in response to the setting of the stop request flag, reel pull-in control for rotating the first stop reel by the determined number of sliding frames is performed. The rotation of the reels is stopped (step 119). Next, it is determined whether or not all the reels 2 to 4 have stopped (step 120). If the second stop reel and the third stop reel have not stopped yet, the process returns to step 116, and the above processes are repeated.
[0066]
When all the reels 2 to 4 are stopped, next, a winning search process is performed by the main CPU 64 (see step 121 in FIG. 9). In the prize search process, the type of the prize flag indicating the combination of symbols actually arranged on the activated prize line matches the type of the internal winning combination determined by the probability lottery process. Then, it is determined whether or not the winning flag is normal (step 122). If the result of this determination is not normal, for example, if the symbol combination of bells is aligned on the activated pay line, but the hit request flag corresponding to the internal winning combination is a cherry flag, the payout number display section An illegal error is displayed at 22 (step 123). If the winning flag is normal, subsequently, a winning command is transmitted to the sub-control board 62 via the sub-control unit communication port 79 (step 124). The winning command is configured to include a 24-bit parameter indicating a winning combination, a game state, and a winning line.
[0067]
Next, depending on the state at that time, a game medal is stored or paid out (step 125). In other words, if the game is played with credits, the number of stored coins displayed on the stored coin number display unit 16 is increased by the number of medals obtained by winning, and the medal is inserted into the medal slot 8 to play the game. Is performed, the number of medals obtained by winning is paid out to the medal tray 34. When medals are stored or paid out, the WIN lamp 21 is turned on to notify the player of occurrence of a prize (step 126).
[0068]
Next, the main CPU 64 determines whether or not the current gaming state is operating the BB game or the RB game (step 127). If the BB game or the RB game is not running, the game processing by the main CPU 64 returns to step 102, and the next new game is started. If the BB game or the RB game is in operation, the number of games in the BB game or the RB game is checked by the main CPU 64 (step 128). Subsequently, the main CPU 64 determines whether or not the current gaming state is at the end of the BB game (step 129). If the BB game has ended, a BB end command is transmitted to the sub-control board 62 (step 130). The BB end command includes a 3-bit parameter indicating an end operation. When the BB end command is transmitted, subsequently, the RAM clear processing at the end of the BB game is performed on the control RAM 66 (step 131), and then the game processing returns to step 102 to start the next new game. Is done. If it is not the end of the BB game in the determination at step 129, the game processing returns to step 102 and the next new game is started.
[0069]
Next, a game process controlled by the sub CPU 82 of the sub control board 62 will be described.
[0070]
FIG. 10 is a flowchart showing an outline of the game processing controlled by the sub CPU 82. In the sub-control board 62, various commands received from the main control board 61 are always analyzed by the sub-CPU 82, and various game processes based on the commands are appropriately performed (see FIG. 10, step 201).
[0071]
FIG. 11 is a flowchart showing an outline of the reception processing when the command received from the main control board 61 is a start command including a pseudo winning flag. In the winning flag receiving process, first, it is determined whether or not the pseudo winning flag transmitted from the main control board 61 in step 115 in FIG. 8 has been received (see step 211 in FIG. 11). If not, the process ends. On the other hand, when the pseudo-winning flag is received, the effect pattern based on the type of the pseudo-winning flag is drawn by referring to the effect pattern selection table (see FIG. 6), and the effect is performed with the determined effect pattern ( Step 212). At this time, if the bonus prize winning flag has been received, the bonus confirmation lamp 19 is turned on, and the number No. which appears only when the bonus is confirmed. 6, No. 7, No. 8, No. The dot matrix display device 24 and the effect spinning reel 25 are displayed in an effect pattern selected from all effect patterns including the thirteen effect patterns (see FIG. 6).
[0072]
Next, it is determined whether or not the pseudo winning flag before one game is a bonus winning winning flag or a winning flag in a bonus inside (between bonus flags) (step 213). This determination is made when the pseudo-winning flag before one game stored in the control RAM 84 is any of the RB winning flag, the BB winning flag, the winning flag during RB inside, or the winning flag during BB inside, “Yes”. , And “No” for other winning flags.
[0073]
If the determination result is "No", the current pseudo-winning flag is stored in the control RAM 84 (step 216), and the winning flag receiving process ends. On the other hand, if the determination result between the above-mentioned bonus flags is "Yes", the pseudo-winning flag before one game is determined whether the current pseudo-winning flag is between the bonus flags (step 214). ). If the current pseudo-winning flag is between the bonus flags, it is determined that the bonus prize-winning flag before one game has been carried over. That is, it is determined that the pseudo winning flag one game before is not a false bonus winning flag but a legitimate bonus winning flag, the current winning flag is stored in the control RAM 84 (step 216), and the winning flag is received. The process ends.
[0074]
On the other hand, if the current winning flag is not between the bonus flags, it is determined that the bonus prize winning flag before one game was a false bonus prize winning flag, and the bonus prize winning effect before one game is set to the false bonus prize winning flag. It is judged that it was the production based on. Therefore, as compensation for the notification of the false bonus internal winning, it is assumed that subsequently, the lottery of the AT game is forcibly won (step 215). At this time, the bonus confirmation lamp 19 for notifying the internal winning in the bonus winning mode is turned off, and the AT confirmation lamp 18 for notifying that the AT lottery has been won is turned on instead. Thereafter, the current pseudo winning flag is stored in the control RAM 84 (step 216), and the winning flag receiving process ends.
[0075]
By this AT winning, a predetermined number of executions is added to the control RAM 84 in which the number of executions of the AT game is stored. Specifically, 30 sets of the number of AT games that can be played in one set are provided unconditionally by this AT winning. In the AT game, a lottery is usually performed for each game, and when the player wins the AT lottery, the number of sets is further selected, and the set number of lotteries is stored and stored in a predetermined area of the control RAM 84. Then, the AT game is activated according to the stored number of sets, and the stop order of the reels 2 to 4 is notified to the player.
[0076]
As described above, according to the slot machine 1 of the present embodiment, if the bonus prize winning flag is not carried over in the next game after the game in which the effect based on the bonus prize winning flag is performed, the pseudo-winning flag before one game is performed. Is a false bonus winning flag, and it is determined that a bonus winning effect based on the false bonus winning flag has been performed. Then, a predetermined number of times, for example, 30 sets of AT games are unconditionally given as compensation for making a false bonus winning effect for the player. Therefore, the player can compensate for the unpleasantness that the bonus prize is not generated even though the effect based on the bonus prize winning flag is performed by the benefit of the AT game. As a result, although an effect based on the bonus prize winning flag is performed, the player does not receive a bonus prize and does not feel unpleasant.
[0077]
In the present embodiment, the effect based on the bonus prize winning flag is performed by lighting the bonus confirmation lamp 19, displaying the dot matrix display device 24 and the effect rotation reel 25, and the like. The effect based on the bonus winning flag may be performed only by displaying the effect rotation reel 25. The effect based on the bonus prize winning flag is effect pattern No. shown in FIG. 0-No. No. 13 which is performed according to all the effect patterns, but appears only when the bonus is confirmed. 6, No. 7, No. 8, No. When an effect is performed in an effect pattern other than the bonus confirmed effect pattern of No. 13, the player cannot determine whether or not the bonus winning is confirmed. Therefore, when an effect is performed in an effect pattern other than the bonus-determined effect pattern, the player does not feel uncomfortable without generating a bonus prize. Therefore, in the case where the effect is performed only by the display of the dot matrix display device 24 and the effect rotating reel 25, the effect of the bonus finalized effect pattern is performed in the previous game, and the winning flag of the current game is set during the bonus period. Only when this is not the case, a configuration in which an AT game is provided can be provided.
[0078]
【The invention's effect】
As described above, according to the present invention, when an effect based on a specific false internal winning mode determined by the false winning mode determining unit is performed by the directing unit, a privilege game advantageous to the player is performed. . Therefore, the player can compensate for the unpleasantness that the specific prize mode is not generated even though the effect based on the specific internal prize mode is performed by the benefit of the privilege game. As a result, the player does not feel unpleasant because the effect based on the specific internal prize mode is performed, but the specific prize mode does not occur.
[0079]
Further, when the effect based on the specific internal winning mode is not performed based on another internal winning mode, the effect based on the specific internal winning mode is performed, so that the internal winning mode is changed to the specific winning mode. Is suggested to the player. Therefore, when an effect other than the effect based on the specific internal prize mode is performed, the player does not recognize that the internal prize mode is fixed to the specific internal prize mode. Therefore, in the case of this configuration, it is sufficient to perform the bonus game only when an effect based on the specific internal winning mode is performed, which indicates that the specific internal winning mode is determined.
