  However, in recent gaming machines, there is a tendency for the gaming state and the role to increase, so when trying to determine the aspect of the production with different probabilities depending on the gaming state and the role, the capacity of the production lottery table increases, As a result, there is a problem that the capacity of the RAM for storing these data increases during the execution of the game.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a gaming machine configured to suppress an increase in the capacity of the effect lottery table even if the gaming state and the combination increase.

  In order to solve the above-described problem, the gaming machine according to the present invention (for example, the slot machine 1 in the embodiment) plays a game by inserting a game medium, and when the combination of symbols for the combination stops on the active line Is a gaming machine which gives a profit including payout of the number of game media corresponding to the combination, and is a main control means for controlling the game (for example, the main control board 100 in the embodiment), and a random value. Random number generating means (for example, second random number generating means 360 in the embodiment) to be generated, effect lottery table storage means (for example, RAM 330 in the embodiment) for storing the effect lottery table in which the winning probabilities of a plurality of effects are determined. And, it has an effect lottery means for extracting a random number value from the random number generating means and performing an effect lottery using an effect lottery table, Sub-control means for controlling the effect along the techniques (e.g., performance control board 300 in the embodiment) configured to include a, a. In such a gaming machine, the random number generation means includes a counter means for storing a random number value having a predetermined number of digits, an update value storage means for storing an update value, and an update value of the update value storage means. An update value setting means for setting, and an update means for acquiring an update value from the update value storage means at a predetermined timing and adding it to the counter means, and the sub-control means is a game controlled by the main control means. An update value predetermined according to the state is configured to be set in the update value storage unit by the update value setting unit, and the effect lottery table is generated from the random number generation unit according to the set update value. The random number value is configured by assigning an effect mode selected in the game state corresponding to the updated value.

  In such a gaming machine according to the present invention, the main control means includes a role lottery means for performing a lottery of a role, and a special role set in advance among the roles is won by the role lottery means, and corresponds to the special role. Special game control means for performing a special game advantageous to the player until a predetermined condition is satisfied when a combination of symbols to be stopped on the active line and winning a prize, and the sub-control means is a main control means In the above, it is preferable that the update value is set by the update value setting means when the special combination is won by the role lottery means.

  Further, in such a gaming machine according to the present invention, the main control means is a re-game probability variation game for performing a re-game probability variation game, which is a game configured so that the winning probability of the re-game player is different from the normal game. Preferably, the sub-control means is configured to set an update value by the update value setting means when the re-game probability variation game control means is executed in the main control means.

  If the gaming machine according to the present invention is configured as described above, the value that can be taken by the random number value generated by the random number generation means changes according to the update value set in the update value storage means. Even using the lottery table, it is possible to select an aspect of the effect with different probabilities according to the updated value. Therefore, even if it is configured to determine the aspect of the effect with different probabilities according to the game state and the combination, it is possible to suppress the increase in the capacity of the effect lottery table, and thereby it is possible to suppress the increase in the capacity of the RAM. In addition, the selection probability of such effects can be changed intentionally according to the gaming state and the like.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, the configuration of the slot machine 1 according to the present invention will be described with reference to FIGS. Here, FIG. 1 is a front view of the slot machine 1, FIG. 2 is a block diagram showing an outline of control of the slot machine 1, and FIG. 3 is a plan view showing an example of a symbol arrangement on the reel outer peripheral surface. FIG. 4 is an explanatory view showing a combination of a combination and a symbol, and FIG. 5 is a block diagram showing a control system in the slot machine 1.

  The slot machine 1 provides a game for acquiring a predetermined number of game medals by aligning the symbols displayed on the reels on a predetermined line, and includes a symbol display means 20 for displaying the symbols, It comprises an operation means 30 that receives the player's operation, a main control board 100 that controls the game, an effect means 40 that provides an effect on the game, and a sub-control board 200 that controls the effect means 40.

  The main control board 100 is a means for overall control including the progress and effects of the game in the slot machine 1 and controls the driving (rotation and stop) control of the role lottery means 110 for performing the lottery of the roles and the symbol display means 20. Reel control means 120 to be performed, stop symbol determination means 130 for determining a symbol when the reel is stopped, payout control means 140 for controlling payout of a game medal at the time of winning, and when a special combination is won by a winning lottery means 110 In addition, it has special role carry-over means 150 for holding the winning state until winning and a game state control means 160 for controlling the progress and state of the game. As shown in FIG. 5, the main control board 100 temporarily stores a main CPU 101 that performs calculations, a random number generator 102 that performs lottery drawing, and data that is captured when the CPU performs various controls. A RAM 103 for storing information, a ROM 104 for storing programs necessary for the progress of games, and an I / F circuit 105 for communicating with the sub-control board 200. Connected and configured to be able to send and receive data.

  The symbol display means 20 is electrically connected to the output side (right side in FIG. 2) of the main control board 100. The symbol display means 20 includes three rotatable reels (left reel 21a, middle reel 21b, right reel 21c) on which various symbols are drawn along the outer peripheral surface of the cylinder, reel driving means (left reel driving means 22a). Medium reel drive means 22b, right reel drive means 22c), and reel position detection means (left reel position detection means 23a, middle reel position detection means 23b, right reel position detection means 23c). . The three reels 21 a to 21 c are provided in parallel in the left-right direction, and are arranged so that three symbols that are continuous in the vertical direction can be seen from the reel display window 11 formed in the front door 3 of the slot machine 1. . Accordingly, the reel display window 11 of the slot machine 1 is arranged so that a total of nine symbols can be seen. For example, as shown in FIG. 3, 21 symbols from No. 0 to No. 20 are displayed on each of the reels 21a to 21c, and are variably displayed in order of increasing numbers. The reel driving means 22a to 22c are constituted by stepping motors or the like, and are connected to the respective rotation center portions of the reels 21a to 21c, and their operations are controlled by the reel control means 120 of the main control board 100. Further, the reel position detecting means 23a to 23c detect the positions of the respective reels 21a to 21c and detect the symbols displayed on the effective lines, and the detected values by the reel position detecting means 23a to 23c are detected. Is read by the main control board 100 and transmitted to the stop symbol determination means 130.

  Here, although not shown, a symbol combination line is provided in a portion including the reel display window 11 of the slot machine 1. The “design combination line” is a design line when the reels 21a to 21c are stopped, and is a line that forms a design combination. In the present embodiment, with respect to the 3 × 3 symbols displayed on the reel display window 11 as described above, the lines provided respectively in the middle, upper, and lower stages in the horizontal direction, and the diagonal directions in the lower right and lower left directions. A total of 5 lines of each line. And three symbols which continue on the upper and lower sides of each reel 21a-21c are located on one or more symbol combination lines, respectively.

  Further, among the five symbol combination lines, an effective line and an invalid line are set from the symbol combination lines according to the number of game medals inserted by the player. In the present embodiment, the “effective line” is a line that is awarded when a combination of symbols corresponding to any combination is stopped on the line. On the other hand, the “invalid line” is generated when the number of inserted game medals is less than a predetermined number (for example, 3), and is a line that is not set as an active line among the symbol combination lines, Even when the corresponding symbol combination is stopped on the line, the profit is not given according to the combination (payout of game medal, etc.). In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

  The operation means 30 is electrically connected to the input side (left side in FIG. 2) of the main control board 100, and the bet button 31 (the bet button 31a and the MAX bet button 31b), the start lever 32, and the stop. Buttons 33 (left stop button 33a, middle stop button 33b, right stop button 33c) are provided. The bet button 31 is a switch operated when the player inserts a stored medal, and the symbol combination line is activated by the operation. The medal insertion slot 51 shown in FIG. 1 is a part where an actual game medal is inserted in order to validate the effective line, like the bet button 31, and the insertion of the game medal from the medal insertion slot 51 is as follows. The operation of the bet button 31 is included.

  In the slot machine 1 according to the present embodiment, the number of game medals that can be inserted in one game is one to three. When the number of inserted sheets is one or when the bet button 31a is operated once, the horizontal horizontal symbol combination line (one line) is set as an effective line, and the remaining four symbols. The combination line is set as an invalid line. When the number of inserted sheets is two, or when the bet button 31a is operated twice, the horizontal middle, upper and lower symbol combination lines (three) are set as effective lines and the remaining lines are set. Two symbol combination lines are set as invalid lines. Furthermore, when the inserted number is 3, or when the bet button 31a is operated three times or when the MAX bet button 31b is operated, all the symbol combination lines (a total of five) are set as effective lines. There is no invalid line. In the slot machine 1 according to the present embodiment, two or three game medals can be inserted and bet in a normal game, and one game in a special game (BB game) described later. The medals can be inserted to bet. In addition, the number of active lines does not change between when two game medals are inserted and when three game medals are inserted (for example, five effective lines are set for any bet number). Is also possible.

  The start lever 32 is a lever that is operated when starting the reels 21a to 21c provided as the symbol display means 20, and has a function as a start operation means. The stop button 33 (33a to 33c) is a button operated by the player when stopping each of the rotating reels 21a to 21c, and has a function as a stop operation means.

  At the start of the game, the player inserts a game medal from the medal insertion slot 51 to bet, or operates the bet button 31 (the bet button 31a or the MAX bet button 31b) to store the game inside. A bet is placed on the medal and the start lever 32 is operated. When the start lever 32 is operated, an operation signal generated at that time is input to the main control board 100. When the main control board 100 receives this operation signal, the main control board 100 determines the effective line and performs the lottery of the combination by the combination lottery means 110. Here, as the combination, as shown in FIG. 4, a plurality of types of special combinations, a plurality of types of small combinations, and a replay (re-playing combination) are provided.

  The special role is a role that, when winning a prize, shifts from a normal game to a special game (a game that can be expected to win a game medal more than a normal game, which is advantageous to the player), and BB (Big Bonus) ) And MB (middle bonus). BB is a role for shifting to a BB game which is one of special games, and MB is a role for shifting to an MB game which is another one of special games. A small combination is a combination in which a predetermined number of game medals are paid out, and the combination of symbols corresponding to the combination and the number of game medals to be paid out differ depending on the type of small combination. Has been. Furthermore, the replay is a replaying role that allows the replaying to be performed while maintaining the number of medals inserted in the game.

  When the winning lottery is performed by the winning lottery means 110, the main control board 100 next controls the reel driving means 22a to 22c to be driven and controlled by the reel control means 120 to rotate all the reels 21a to 21c. To do. In this way, the reels 21a to 21c are rotated by the reel driving means 22a to 22c, so that the symbols on the reels 21a to 21c are variably displayed in the vertical direction in the reel display window 11 at a predetermined speed.

  When the player operates each of the stop buttons 33a to 33c, an operation signal generated at that time is input to the main control board 100. In a state where the reels 21a to 21c are variably displayed, the main control board 100 monitors the input of this operation signal by the player's stop operation, and upon receiving this operation signal, the reel control means 120 The reel driving units 22a to 22c corresponding to the stop buttons 33a to 33c are driven and controlled to stop the reels 21a to 21c related to the reel driving units 22a to 22c. When the main control board 100 detects that the rotation of all the reels 21a to 21c has been stopped by the above operation, the stop symbol determination means 130 makes the winning combination by the above-described combination lottery means 110 on the active line. It is determined whether or not the corresponding symbol has stopped, that is, whether or not a winning combination has been won. If any winning combination has been won, the payout control means 140 pays out a game medal or the gaming state control means 160 Control the gaming state.

  Here, the gaming state in the slot machine 1 will be described with reference to FIG. FIG. 6 is a diagram showing the transition of the gaming state. When the slot machine 1 is reset (also called “RAM clear”), the gaming state control means 160 executes the normal gaming control means 161, The slot machine 1 becomes a normal game (not inside) J1. Here, “non-inside” means a state in which a special role is not won as in RAM clear. When the special combination is won by the combination lottery means 110, the game shifts to the normal game (inside) J2. Here, “inside” means a state in which a special role is won but the symbols corresponding to this special role are not aligned on the active line (no winning), and the game state control In the means 160, the normal game control means 161 is continuously executed. When the transition is made to the normal game (inside) J2, the special combination carry-over means 150 carries over the winning combination until the winning special combination is won (that is, the state of the normal game (inside) J2 is continued). .

  In the normal game (inside) J2, when the symbols corresponding to the special role won on the active line are arranged, the game state control means 160 executes the special game control means 162, and the slot machine 1 is assigned to the special game J3. Become. When the transition is made to the special game J3, a game advantageous to the player who can expect to acquire a game medal more than the normal game is executed until a predetermined end condition is satisfied. Here, the predetermined end condition is, for example, a case where a predetermined number of game medals are paid out to the player.

  Then, in the special game J3, when a predetermined end condition is satisfied, or when a predetermined condition is satisfied (for example, a predetermined small role is won) when the player is in the normal game (non-inside) J1, the gaming state The control means 160 executes the re-game probability variation game control means 163, and the slot machine 1 shifts to a re-game probability variation game (not inside) J4. A re-game probability variation game is a game in which the winning probability of a re-game player (replay) is different from that of a normal game (this game state is also called “replay time (RT)”. Will be set higher than the normal game). In this re-game probability variation game (non-internal) J4, if a special role is won, the game moves to a re-game probability variation game (inside) J5, and if a special role is won in this state, the game moves to special game J3. Also in this case, when the transition is made to the replay probability variation game (inside) J5, the winning combination is carried over by the special combination carry-over means 150 until the winning special combination is won. On the other hand, when a predetermined combination (for example, a predetermined small combination) is won in the replay probability variation game (non-inside) J4 and the symbols corresponding to this combination are aligned on the active line, the game state control means 160 The game control means 161 is executed, and the slot machine 1 shifts to a normal game (non-inside) J1.

  In any gaming state, when a small role is won and a prize is won, a predetermined number of game medals are paid out by the payout control means 140, and when a replay (regamer) is won and a prize is won, a replay is executed. It is comprised so that. Further, the above description of the gaming state is an example, and the present invention is not limited to the transition of the gaming state.

  By the way, in such a slot machine 1, the main control board 100 for controlling the game and the sub-control board 200 for controlling the effect for the game are separated so that the game result cannot be influenced from the outside. Configured. Therefore, the main control board 100 is configured to transmit to the sub control board 200 a control command including information related to the game such as the above-described winning result and game state in order to control the effect executed on the sub control board 200. The sub-control board 200 receives this control command and determines the mode of the effect, and the image display device 41, the various effect lamps 42, and the sound emission part (speaker) constituting the effect means 40. 43 is configured to produce effects using video, light, and sound effects. Here, the sub-control board 200 includes the above-described image display device 41, various effect lamps 42, and sound emission according to the effect control board 300 that controls the effect and the aspect of the effect determined by the effect control board 300. The image sound generation substrate 400 that controls the unit 43 is included.

  FIG. 7 is an explanatory diagram showing an example of a flow of control commands transmitted from the main control board 100 to the effect control board 300 in one game. When the main control board 100 can execute the game, a game state command C500 is transmitted. When a player inserts a game medal or operates the bet button 38 (the bet button 38a or the MAX bet button 38b), a bet command C501 is transmitted and the reel 21 can be started to rotate. Then, the rotation rotation start acceptance command C502 is transmitted. Further, when the start lever 32 is operated by the player, the condition device state number command C503 for instructing the determination of the production mode including the result of lottery and the game state, and the rotation start command C504 are continuously performed. Sent. Each time the three stop buttons 33a, 33b, and 33c are pushed by the player and the rotation of the corresponding reels 21 (21a, 21b, and 21c) is stopped, the first stop acceptance command C505 and the rotation of the spinning cylinder are stopped. A command C506, a second stop acceptance command C507, a rotation rotation stop command C508, a third stop reception command C509, and a rotation rotation stop command C510 are transmitted, and finally an all rotation rotation stop command C511 is transmitted. .

  In the sub control board 200, the effect control board 300 and the image sound generation board 400 are connected to a bus 210 as shown in FIG. The effect control board 300 is provided with a sub CPU 310, a random number generator 320, a RAM 330, a ROM 340, and an I / F circuit 350, which are connected to the bus 210. On the other hand, the image sound generation board 400 is provided with an image control IC 410 and a sound source IC 440 connected to the bus 210 described above. Further, a video RAM 420, an image ROM 430, and an image display device 41 are connected to the image control IC 410. Further, a sound source ROM 450 and an amplifier 460 are connected to the sound source IC 440, and upper and lower speakers 43 (43a, 43b) are connected to the amplifier 460. In addition, the above-described various effect lamps 42 (42a, 42b) are also connected to the bus 210, and the lighting / extinguishing operation thereof is controlled by the effect control board 300.

  The sub CPU 310 expands and executes the effect control program recorded in the ROM 340 in the RAM 330, and controls the image control IC 410 and the sound source IC 440 provided on the image sound generation substrate 400 to control the image display device 41 and the speaker 43 ( 43a, 43b) is used to produce a game with video and sound effects. The video displayed on the liquid crystal display device 41 is displayed when the image control IC 410 expands and executes the image information stored in the image ROM 430 on the video RAM 420 and is displayed on the speaker 43 (43a, 43b). The output sound effect (music, voice, sound effect, etc.) is reproduced from the sound information extracted from the sound source ROM 450 by the sound source IC 440 and output from the speaker 43 (43a, 43b) via the amplifier 460.

  The effect executed by the sub CPU 310 is determined according to the control command received by the sub CPU 310 via the I / F circuit 350, as described above, from the main control board 100. Although controlled, a part of the effect mode (pattern) is configured to be determined using the random number value generated by the random number generator 320 provided in the effect control board 300, and the rest The second random number generating means, which is executed as a part of the sub CPU 310 program, is used.

  Now, with reference to FIGS. 8 and 9, a configuration in which the effect mode is determined by using the random number value generated by the second random number generator in the effect control board 300 will be described. Here, FIG. 8 is an explanatory diagram showing a configuration of processing in the effect control board 300, and FIG. 9 is an explanatory diagram showing a data structure of the effect lottery table 331. As shown in FIG. 8, the effect control means 311 read from the ROM 340 is executed in the sub CPU 310 of the effect control board 300. The effect control means 311 has effect lottery means 312 and is configured to perform effect drawing lottery using the effect lottery table 331 stored in the RAM 330. In the effect control board 300, the second random number generation unit 360 includes a random value acquisition unit 365, an update unit 363, an update value setting unit 364 executed by the sub CPU 310, and a counter unit 361 stored in the RAM 330. And update value storage means 362.

  The effect lottery table 331 stored in the RAM 330 is provided corresponding to the winning combination lottered on the main control board 100. For example, as shown in FIG. It is composed of a plurality of tables such as 331a and a table 331b when the result of lottery is “small role 1 (bell-bell-bell)” (in this slot machine 1, each role shown in FIG. A corresponding production lottery table and a production lottery table in the event of a loss). In such an effect lottery table 331a, 331b, etc., an effect selected for each random value is set in correspondence with the range of random values generated by the second random number generator 360 (for example, In the case of FIG. 9, a case is shown in which a value of 0 to 199 is generated as a random number value).

  The update means 363 of the second random number generation means 360 is repeatedly executed at a predetermined timing, and executes a process of reading the update value stored in the update value storage means 362 and adding it to the counter means 361. For example, when “1” is set in the update value storage unit 362, the value stored in the counter unit 361 increases by 1 when the update unit 363 is executed. Note that the length of data that can be stored in the counter unit 361 is limited, and the numerical value overflowing from the upper digit is ignored when the length exceeds this length (that is, the counter unit 361 is configured to be ignored). The maximum possible value is determined by the length of the data). The update value stored in the update value storage unit 362 is configured to be changeable by the update value setting unit 364.

  The processing of the effect control board 300 having such a configuration will be described with reference to FIG. Here, FIG. 10 is a processing flow for setting an update value in the update value storage means 362 and performing a lottery of a mode of effect.

(Update value setting)
As shown in FIG. 10, the effect control means 311 detects the reception of the game state command C500 and the condition device state number command C503 among the control commands transmitted from the main control board 100 (step S600). The lottery result of the combination is acquired from the state number command C503 (step S610). Further, the game state is acquired from the game state command C500 (step S620). Here, the game state command C500 and the condition device state number command C503 include a lottery result of the combination by the combination lottery means 110 and a gaming state such as a normal gaming state, a special gaming state, and a re-gaming probability variation gaming state, In addition, in the case of inside, information on which special role has been won and entered inside is also included. Then, the effect control means 311 determines whether or not the combination of the winning combination and the gaming state on the main control board 100 has changed from the lottery result of the winning combination acquired in step S610 and the gaming state acquired in step S620 (step S630). If it is determined that the change has not occurred, the process proceeds to step S670. If it is determined that the change has occurred, an update value corresponding to the combination of the combination and the gaming state is transmitted to the update value setting unit 364 to be updated value storage unit 362. (Step S640). At this time, it is determined whether or not the set update value is “1” (step S650). If it is not “1”, the update unit 363 sets the counter unit 361 to a predetermined value (step S660). . Here, the predetermined value may be always set to “0”, or may be set to a multiple of the update value closest to the value currently stored in the counter means 361. (For example, if the update value is “5” and the value stored in the counter means 361 is “32”, it is set to “35”).

  For example, in the case of the data structure of the effect lottery tables 331a and 331b shown in FIG. 9, when the game state is the normal game state, regardless of the lottery result of the combination (such as “losing” or “small role 1”). When “1” is set as the update value and the game state is the re-game probability variation game state, “10” is set as the update value regardless of the lottery result of the combination. In addition, when the special combination 1 is won and it is in the inside, if the combination lottery result is “out of”, the update value is set to “5”, and the combination lottery result is “small combination 1”. In this case, “50” is set as the update value. Further, when the special combination 2 is won and the inside is in the middle, if the combination lottery result is “out of”, the update value is set to “50” and the combination lottery result is “small combination 1”. At this time, “5” is set as the update value. (Although not shown in FIG. 9, predetermined setting values are also set for combinations of lottery results and game states of other combinations). In this manner, by changing the update value, the possible value of the random value set in the counter unit 361 changes. For example, when “1” is set as the update value, 200 values of 0, 1, 2,..., 199 are generated as random numbers, and “5” is set as the update value. 40, 0, 5, 10,..., 195 are generated as random values, and when “10” is set as the update value, 0, 10, 20,. .., 190 are generated as random values, and when “50” is set as the update value, four values of 0, 50, 100, and 150 are generated as random values.

  In the example shown in FIG. 10, the case where the update value is set when there is a change in the combination of the lottery result of the combination and the gaming state is described, but the present invention is limited to this setting timing. For example, it is configured to be set after a predetermined number of games are executed from a game in which the game state is changed to an internal game or a replay probability variation game, or the above condition is satisfied It can be configured to be set when, for example, a predetermined operation means among the operation means is operated after the next game or a predetermined time has elapsed.

(Lottery for production)
Next, the effect control means 311 acquires the random value stored in the counter means 361 by the effect lottery means 312 via the random number acquisition means 365 of the second random number generation means 360 (step S670). An effect mode (effect pattern) corresponding to the random number acquired from the second random number generator 360 is determined with reference to the effect lottery table 331 corresponding to the lottery result acquired in step S610 (step S680). The determined effect mode (effect pattern) is transmitted to the image sound generation board 400 and the effect is executed (step S690).

  As described above, since a predetermined update value is set for each combination of the lottery result of the combination and the gaming state, a random value generated according to these combinations changes. For example, in the case shown in FIG. 9, the performances A, E, K, and O corresponding to the random values 0, 50, 100, and 150 that are generated when the update value is “50” are highly reliable for the winning result of the role. If you assign a production, when you win the special role 2 and you are in the inside, when you win “out of”, and when you win the special role 1 and you are in the inside, when you win the “small role 1” A highly reliable performance is always selected. On the other hand, among the random values generated when the update value is “5”, the effects C, I, etc. corresponding to the random values 15, 75, etc. excluding the random value generated when the update value is “50” are won. If a performance with a low degree of reliability is assigned to the result, when “Special” 1 is elected and “Inside” is won, “Special” 2 is elected, and when “Special” 2 is elected and “Inside” When "" is won, either a highly reliable performance or a low reliability performance is selected according to the lottery result. The same applies to the case where the update value is “1” and “10”.

  In this way, an update value is set for each combination of the lottery result of the combination and the gaming state, and a predetermined effect mode is assigned to the random value generated by the update value. Using one production lottery table 331, the production mode can be selected with a different probability for each gaming state. Therefore, even if it is configured to determine the effect mode with different probabilities according to the game state and the role, there is no need to provide a different effect lottery table 331 for each game state, and the data amount of the effect lottery table 331 is reduced. Therefore, it is possible to prevent the capacity of the RAM 331 mounted on the effect control board 300 from increasing. In addition, the selection probability of such effects can be intentionally changed according to the gaming state or the like.

  In the above description, when the condition device state number command C503 is received from the main control board 100, the case where the update value is set and the effect mode lottery is selected is described. The present invention is not limited to this configuration, and the update value setting and the effect drawing lottery can be executed when different control commands are received. For example, an update value setting process (corresponding to steps S600 to S660 in FIG. 10) is executed when the gaming state command C500 is received, and a rendering mode lottery process (when the condition device state number command C503 is received) ( 10 (corresponding to steps S670 to S690 in FIG. 10).

  Further, here, the processing in the case of performing the lottery of the production mode using the random number value generated by the second random number generating means 360 has been described. However, in addition to this random number value, the hardware generated by the random number generator 320 is described. It is also possible to configure such that a lottery of effects is performed in combination with a random number.

  Furthermore, although the above description demonstrated the case where this invention was applied to the slot machine 1 which is a kind of game machine, it can be applied also to other game machines, such as a pachinko machine.
