Abstract

<P>PROBLEM TO BE SOLVED: To satisfy the tendency of demanding a pachinko slot machine by which a game player can feel the sense of continuous winnings, and also, wherein the skill of the game player is easier to be reflected to a game result, and which has an amusement in the game. <P>SOLUTION: A main CPU 64 judges whether the game state is a general game state in a high probability Yakumono (JAC) game or not (a step 501). When the game state is not the general game state in the high probability JAC game, the main CPU 64 judges whether a "group combination" is drawn by a lottery or not (a step 502). When the "group combination" is drawn by the lottery, a stopping table by which a "small winning combination of a bell" is established without fail regardless of the operation timing of stop buttons 31 to 33, or a stopping table by which any winning combination is not established is selected (steps 503 to 508). When the "group combination" is drawn by the lottery under the state wherein the game state is the general game state in the high probability JAC game, a stopping table by which the "small winning combination of Dekachiri" is established only when the stop buttons 31 to 33 are operated by a specified timing is selected (a step 509). <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a gaming machine in which a gaming state shifts.

  Conventionally, as this type of gaming machine, for example, there is a so-called pachislot machine in which the rotation of a reel stops in response to an operation of a stop button. In a general pachislot machine, three reels are arranged in three rows behind the front panel. Various symbols are drawn on the outer periphery of each reel, and these symbols are observed through each window formed on the front panel. The game starts when the player operates the start lever in a state where a medal as a game medium is bet. When the start lever is operated, the reel rotates, and the symbols drawn on the outer periphery of the reel are variably displayed on each window. When operating the start lever, an internal winning combination is determined by lottery from a plurality of internal winning combinations. When a stop button provided corresponding to each reel is operated, the rotation of the reel is stopped and the symbol is stopped and displayed on each window. When the combination of the symbols displayed in a stopped state is a combination corresponding to the determined internal winning combination, the number of medals corresponding to the internal winning combination is paid out.

However, in the pachislot machine, even if the internal winning combination is determined, the symbol combination corresponding to the internal winning combination cannot be stopped and displayed unless the stop button is operated at a predetermined timing. In this way, the game is made interesting by reflecting the skill of the player in the game result. In addition, some pachislot machines may perform an SB game (single bonus game) in the next one unit game when a symbol combination corresponding to a predetermined internal winning combination is stopped and displayed. The number of medals that can be acquired in the SB game is smaller than other bonus games such as the BB game (big bonus game) and the RB game (regular bonus game). However, like the pachislot machine shown in Patent Document 1 below, by shifting the gaming state to the SB concentration state in which the lottery probability of the internal winning combination of the SB game is higher than the general gaming state, The SB winning can be established and the feeling of winning consecutively can be enjoyed, and the game can be interesting.

  However, the player tends to demand a pachislot machine that not only allows the player to taste the winning streak as the game is repeated, but also makes the player's skill more easily reflected in the game result and has an interesting game.

  The present invention has been made in order to solve the above-described problems, and includes a variation display means for variably displaying a symbol, a variable display stop requesting means for requesting the variability display stop of the symbol on the variation display means, and a game Game state transition means for transitioning the state, internal winning combination lottery means for lottering any internal winning combination from among a plurality of internal winning combinations, and variable display control means for controlling the variable display of symbols on the variable display means The internal winning combination lottery means is configured to be able to draw a group combination consisting of a predetermined combination of internal winning combinations and an internal winning combination of a special game (for example, SB game) advantageous to the player, When the predetermined condition is established, the transition means shifts the gaming state to a special game concentration state where the lottery probability of the internal winning combination of the special game by the internal winning combination lottery means is higher than before the transition, and the variable display control means When a group combination is drawn by the internal winning combination lottery means in one of the game states before or after the transition to the special game concentration state by the technique state transfer means, it is related to the timing of the stop request from the variable display stop request means. First, the symbol combination corresponding to a specific internal winning combination included in the group combination is stopped and displayed on the variable display means, and when the group combination is drawn by the internal winning combination lottery means in the other game state different from this, the variable display is displayed. Only when a stop request is made at a predetermined timing from the stop request means, the symbol combination corresponding to another internal winning combination different from the specific internal winning combination included in the group role is stopped and displayed on the variable display means. And

  According to this configuration, when a group combination is drawn in one game state before or after the transition to the special game concentration state, it is included in the group combination regardless of the timing of the stop request from the variable display stop request means. The symbol combination corresponding to the specific internal winning combination is stopped and displayed on the variation display means. On the other hand, if a group combination is drawn in a different game state, it will differ from a specific internal winning combination included in the group combination only when a stop request is made at a predetermined timing from the variable display stop request means. The symbol combination corresponding to the internal winning combination is stopped and displayed on the fluctuation display means.

  Further, the present invention is characterized in that, in the gaming state before and after the transition to the special game concentration state by the gaming state transition means, the expected value indicating the payout per unit bet number of gaming media for at least the group combination is substantially equal. To do.

  According to this configuration, the expectation of the payout amount obtained by the player for at least the group combination before and after the transition from the gaming state to the special game concentration state can be made substantially equal.

  According to the present invention, as described above, when a group combination is drawn in one game state before or after the transition to the special game concentration state, the timing of the stop request from the variable display stop request means Regardless, the symbol combination corresponding to the specific internal winning combination included in the group combination is stopped and displayed on the variation display means. On the other hand, if a group combination is drawn in a different game state, it will differ from a specific internal winning combination included in the group combination only when a stop request is made at a predetermined timing from the variable display stop request means. The symbol combination corresponding to the internal winning combination is stopped and displayed on the fluctuation display means. For this reason, in a gaming state in which it is necessary to make a stop request for a symbol corresponding to another internal winning combination included in the group combination, the player's skill is more reflected in the number of game media acquired. That is, an expert who can perform a stop requesting operation at a predetermined timing at which a symbol combination corresponding to another internal winning combination stops and displays can acquire a large number of game media. On the other hand, a beginner who is difficult to perform a stop requesting operation at this predetermined timing cannot acquire so many game media. As a result, many special games (for example, SB games) can be won in a special game concentration state, and the game can be enjoyed in succession. Interest that can be acquired is added. In addition, when a group combination is drawn lottery, the type of internal winning combination that is stopped and displayed before and after the transition of the game state and the stop request timing in the variable display stop request means are different. This also enhances the fun of the game. As a result, the player can feel fun by playing the game.

  In addition, in a configuration in which the expectation of the dividend amount for at least the group role can be made substantially equal before and after the transition to the game state to the special game concentration state, the game store must have a skilled player obtain a large amount of game media. The amount of game media that can be acquired by all players through each game state can be made constant.

Each symbol is assigned a code number of 00 to 20, and this code number is stored in a program ROM 65 (see FIG. 4) described later as a data table. In each symbol row, symbols of “red 7”, “blue 7”, “watermelon”, “upper chilli”, “lower chilli”, “replay”, and “bell” are represented.

  Next, an outline of the game performed in the pachislot machine 1 according to the present embodiment will be described.

  The gaming state in the present embodiment includes a plurality of types of gaming states such as “general gaming state”, “BB general gaming state”, “RB gaming state”, and “SB gaming state”. The “general gaming state” further includes a “general gaming state in a high-probability character” and a “general gaming state in a normal-probability character”. Each of these gaming states is basically distinguished based on the types of roles that may be won internally and the probability of winning internally in SB described later.

  In the present embodiment, the bonus is held as an internal winning combination over a plurality of unit games after the internal winning of the bonus of BB (Big Bonus) or RB (Regular Bonus) until the unit game where the bonus is won. (Generally referred to as “carryover”).

  The “high-probability-general general gaming state” is a state in which the probability of internally winning “SB” is higher than the normal-probability-general general gaming state (a state in which a high-probability role-in-progress flag described later is ON). This “general gaming state in a high-probability character” is also referred to as “SB concentration state”. The “general gaming state in normal probability bonus” refers to a state in which the probability of winning internally in “SB” is normal (a state in which a high probability bonus flag to be described later is OFF). The condition for generating the “general gaming state in a high-probability role” is to win a high-probability role start by a lottery performed in a high-probability role control process (see FIG. 19) described later. The end condition of “general gaming state in high-probability bonus” is to win the end of high-probability bonus by a lottery performed in the high-probability bonus control process (see FIG. 5) described later.

  FIG. 3 is a diagram showing a combination and a payout number corresponding to a winning symbol combination in each gaming state.

  In the BB winning, “red 7”-“red 7”-“red 7” or “blue 7”-“blue 7”-“blue 7” are arranged along the activated winning line in the “general gaming state”. It is established by. When the BB winning is established, 15 medals are paid out, and the gaming state becomes the “BB general gaming state”. RB wins are “red 7”-“red 7”-“blue 7” lined up along the activated pay line in “general gaming state”, or “replay” in “BB general gaming state” — "Replay"-"Replay" is established by lining up along the activated pay line. The establishment of RB winning in the “BB general gaming state” is generally referred to as “JAC IN”. When RB winning is established, 15 medals are paid out, and the gaming state becomes “RB gaming state”. The SB winning is established by arranging “blue 7”-“bell”-“bell” along the activated winning line in the “general gaming state”. When the SB winning is established, 10 medals are paid out, and the gaming state becomes the “SB gaming state”. In the pachislot machine 1 of the present embodiment, when the bonus is internally won in the “general gaming state”, the bonus winning can be established in the “general gaming state”.

  The “replay” winning is established by arranging “replay”-“replay”-“replay” along the activated winning line in the “general gaming state”. When the “re-game” winning is established, the same number of medals as the number of inserted medals are automatically inserted in the next unit game, and the player can play the next unit game without consuming medals. In addition, when “Replay”-“Replay”-“Replay” is aligned with the activated pay line in the “RB gaming state”, a “combination” winning is established and 15 medals are paid out.

  In the “general gaming state” and the “BB general gaming state”, “Watermelon”-“Watermelon”-“Watermelon” are lined up along the activated winning line, and the “watermelon small part” winning is established. When the winning “watermelon small role” is established, 10 medals are paid out. In addition, “Bell”-“Bell”-“Bell” is lined up along the activated winning line, thereby winning the “bell small part” winning. When the winning of “Bell's small role” is established, seven medals are paid out. In addition, “Upper Chile”-“ANY”-“ANY” is lined up along the activated winning line, and the “Upper Chile Minor” win is established. Here, “ANY” represents a meaning regardless of the type of symbols to be stopped and displayed on the activated pay line. When the winning of “Upper Chile Minor” is established, two medals are paid out. Also, “Lower Chile”-“ANY”-“ANY” is lined up along the activated winning line, and the “Lower Chile Minor” win is established. When a prize for “Little Chile” is established, six medals are paid out. When the “upper Chile small role” and the “lower Chile small role” are combined, the “Deca Chile small role” is established, and a total of 14 medals are paid out. “Decachiri's small role” and “Bell's small role” constitute a “group role”, and in the “general game state in the normal probability role”, the winning of “Bell small role” can be established. In the “general gaming state in the high-probability role”, the winning of “Decachiri small role” can be established.

  FIG. 4 and FIG. 5 show circuit configurations configured on the main control board 61 and the sub control board 62 that control the game processing operation of the pachislot machine 1 described above.

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

  The main CPU 64 includes a clock pulse generation circuit 67 and a frequency divider 68 for generating a reference clock pulse, a random number generator 69 for generating a certain range of random numbers, 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 a signal to / from a peripheral device (actuator) described later is connected. The main CPU 64 performs game processing by a sequence program stored in a program ROM 65 described later.

  The main CPU 64 constitutes an internal winning combination lottery means for drawing one of the internal winning combinations from a plurality of internal winning combinations including the SB internal winning combination of the SB game as a special game and the “group role”. Yes. In addition, the main CPU 64 has a gaming state in which the gaming state is shifted between the above-described “high-probability-general general gaming state” and “normal-probability-general general gaming state” having a high SB internal winning combination lottery probability. It constitutes a transition means. In the present embodiment, the game state transition means determines whether the “high game probability general game state” and “normal probability bonus medium” according to the lottery result performed in a high probability bonus control process (see FIG. 19) described later. The game state is shifted to the “general game state”. Further, the main CPU 64 constitutes a variable display control means for controlling the variable display of symbols on the reels 2 to 4. The variable display control means, when “group role” is drawn as an internal winning combination in “general game state in normal probability combination”, and a stoppage table (see FIG. 10) that can be established as a bell winning is used as the stop table The combination of the symbol “bell” corresponding to the “bell small part” included in the “group combination” is stopped and displayed on the activated winning line regardless of the operation timing of the stop buttons 31 to 33. On the other hand, if “group role” is drawn as an internal winning combination in “general gaming state in high probability game”, the symbols “upper chile” and “lower chile” will be drawn on the activated pay line Only when the stop buttons 31 to 33 are operated, the combination of the symbols “upper chilli” and “lower chilli” corresponding to the “small chisel” included in the “group win” is stopped on the activated pay line. To do. In the present embodiment, the predetermined timing is a timing at which the symbols “upper chilli” and “lower chilli” are within the range of four frames from the activated pay line.

  The program ROM 65 has a storage section that stores various tables, sequence programs, and the like used for the game processing of the pachislot machine 1.

  Various tables stored in the program ROM 65 will be described with reference to FIGS.

  FIG. 6 is a diagram conceptually showing a probability lottery table for a normal game state general game state and a high probability player general game state probability lottery table among probability lottery tables used for the internal winning combination lottery. is there.

  Each probability lottery table is used to divide the random number extracted by the sampling circuit 70 into each internal winning combination, and stores data for dividing a predetermined range of random numbers generated by the random number generator 69 into each internal winning combination. ing. Each numerical value in the figure is a lottery value indicating a numerical range in which each internal winning combination is lottered among the random number range of “16384” generated by the random number generator 69 from “0 to 16383”. The lottery probability of each internal winning combination is represented by a numerical value having “16384” as a denominator and a lottery value as a numerator.

  FIG. 4A is a probability lottery table for normal game state in normal probability combination used in “general game state in normal probability combination”. When this table is used, the probability that the BB internal winning combination will be drawn is “50/16384”. Further, the probability that the RB internal winning combination will be drawn is “40/16384”. The probability that the SB internal winning combination will be drawn is “737/16384”. In addition, the probability that the group combination internal winning combination will be drawn is “6070/16384”. Further, the probability that the watermelon internal winning combination will be drawn is “100/16384”. In addition, the probability that the upper Chile internal winning combination will be drawn is “49/16384”. The probability that the lower Chile internal winning combination will be drawn is “4/16384”. The probability that the re-game internal winning combination will be drawn is “2245/16384”. Further, the probability that a lose will be drawn is “7089/16384”.

  FIG. 4B is a probability lottery table for a general game state in a high-probability role used in the “general game state in a high-probability role”. When this table is used, the probability that the internal winning combination of BB, RB, group role, watermelon, upper chile, lower chile, and replay will be drawn is the case where the table shown in FIG. The probability that the SB internal winning combination will be drawn is “7370/16384”, and the probability that the SB internal winning combination will be drawn compared to the case where the table shown in FIG. Is high. In addition, the probability that lots will be drawn is “456/16384”, and the probability that lots will be drawn is lower than when the table shown in FIG.

  FIG. 7 is a diagram conceptually showing the high-probability accessory start lottery table.

  The high probability bonus start lottery table is a table used when determining whether or not to shift the gaming state to the “general gaming state in high probability bonus” in the high probability bonus control process (see FIG. 19) described later. It is. The high probability combination starting lottery table stores data for dividing the extracted random number into winning (start) and non-winning. Each numerical value in the figure is a lottery value indicating a numerical value range in which winning or non-winning is lottered in a random number range of “1024” from “0 to 1023”. Winning and non-winning lottery values are “1” and “1023”, respectively. The lottery probability of winning or not winning is represented by a numerical value having “1024” as a denominator and a lottery value as a numerator.

  FIG. 8 is a diagram conceptually showing a high-probability accessory end lottery table.

  The high probability bonus end lottery table is a table used to determine whether or not to end the “general gaming state in high probability bonus” in the high probability bonus control process (see FIG. 19) described later. The high probability combination end lottery table stores data for dividing the extracted random number into winning (end) and non-winning. Each numerical value in the figure is a lottery value indicating a numerical value range in which winning or non-winning is lottered in a random number range of “1024” from “0 to 1023”. The lottery values for winning and not winning are “10” and “1014”, respectively. The lottery probability of winning or not winning is represented by a numerical value having “1024” as a denominator and a lottery value as a numerator.

  Next, with reference to FIG. 9, the relationship between the gaming state, the internal winning combination, and the selected stop table group will be described.

  FIG. 9 is a diagram illustrating the relationship between the internal winning combination and the type of stop table group to be selected in the “general gaming state in the normal probability combination” and the “general gaming state in the high probability combination”.

  Each stop table group is used for stop control of each of the left, middle, and right reels 2 to 4, and a stop table group is selected for each gaming state and type of internal winning combination. Each stop table is set with a “pull-in rate” representing the probability that the symbol combination corresponding to the internal winning combination is aligned with the activated winning line when the stop buttons 31 to 33 are operated at random.

  For example, as shown in the figure, when the game state is “general game state in normal probability combination”, when the BB internal winning combination is drawn, the BB winning establishment stop table group is selected. In the BB winning establishment possible stop table group, the “drawing rate” of the symbol corresponding to the BB winning is “325/9261”. In addition, when the RB internal winning combination is drawn, the RB winning establishment possible stop table group whose symbol “retraction ratio” corresponding to the RB winning is “250/9261” is selected. In addition, when the SB internal winning combination is drawn, the SB winning combination possible stop table group in which the “drawing rate” of the symbol corresponding to the SB winning is “3087/9261” is selected. In addition, when the “group role” is drawn, the “draw rate” of the symbol corresponding to the bell winning is “9261/9261,” that is, the bell winning establishment stop table group in which the bell winning is always established, A table of all winning combination winning / failing stop tables for which an internal winning combination winning is not established is selected. Which table group is selected is determined by lottery using a stop table group selection table (see FIG. 13) described later. Further, when the watermelon internal winning combination is drawn, the stop table group capable of establishing a watermelon winning with the “retraction rate” of the symbol corresponding to the watermelon winning “2470/9261” is selected. In addition, when the upper Chile internal winning combination is drawn, a stop table group in which an upper Chile winning establishment is possible with the “drawing rate” of the symbol corresponding to the upper Chile winning being “4410/9261” is selected. In addition, when the lower Chile internal winning combination is drawn, a stop table group in which a lower Chile winning establishment is possible with a “draw rate” of the symbol corresponding to the lower Chile winning is “2205/9261” is selected. In addition, when the replay internal winning combination is drawn, the “draw rate” of the symbol corresponding to the replay winning is “9261/9261”, that is, the replay winning establishment possible stop table group in which the replay winning is always established is selected. . In addition, when the winning internal winning combination is drawn, the all winning combination winning stoppage table group is selected. On the other hand, when the gaming state is “general gaming state in high-probability role”, when BB, RB, SB, watermelon, upper chile, lower chile, replay, or loser is drawn as an internal winning combination, The same stop table group as that used in the “general game state in bonus item” is selected according to the internal winning combination. Further, when the “group role” is drawn, a stop table group that can be established for a big prize winning with a “draw rate” of the symbol corresponding to the big prize winning is “1323/9261” is selected.

  Next, the expected value indicating the payout per medal bet will be described.

  The “expected value” R of each internal winning combination is generally represented by the following formula (1) using the above-described pull-in rate.

  R = (medal payout number / medal wager number) × {lottery value of internal winning combination / (total random number range−replay lottery value)} × (draw rate) (1)

  However, in the case of winning a bell in a group role, the pull-in rate is a value obtained by multiplying the above formula (1) by the probability (2646/9261) that a stop table group capable of establishing a bell winning is selected. The expected value Rt for the entire game is represented by the sum of the “expected value” of each internal winning combination.

In the case of the “general gaming state in the normal probability combination”, the expected value R of each internal winning combination is as follows.
Expected value of BB R = (15/3) × {50 / (16384-2245)} × (325/9261) = 0.00062
Expected value of RB R = (15/3) × {40 / (16384-2245)} × (250/9261) = 0.00038
Expected value of SB R = (10/3) × {737 / (16384-2245)} × (3087/9261) = 0.05792
Expected value of group role R = (7/3) × {6070 / (16384-2245)} × (2646/9261) × (9261/9261) = 0.28621
Expected value of watermelon R = (6/3) × {100 / (16384-2245)} × (2470/9261) = 0.00377
Expected value of upper dust R = (2/3) × {49 / (16384-2245)} × (4410/9261) = 0.110
Expected value of lower Chile R = (12/3) × {4 / (16384-2245)} × (2205/9261) = 0.00027

Then, the expected value Rt in the “general gaming state in the normal probability combination” is as follows.
Rt = 0.00062 + 0.00038 + 0.05792 + 0.28621 + 0.00377 + 0.00110 + 0.00027 = 0.39869

Further, in the case of the “general gaming state in a high probability combination”, the expected value R of each internal winning combination is as follows.
Expected value of BB R = (15/3) × {50 / (16384-2245)} × (325/9261) = 0.00062
Expected value of RB R = (15/3) × {40 / (16384-2245)} × (250/9261) = 0.00038
Expected value of SB R = (10/3) × {7370 / (16384-2245)} × (3087/9261) = 0.57917
Expected value of group role R = (14/3) × {6070 / (16384-2245)} × (1323/9261) = 0.28621
Expected value of watermelon R = (6/3) × {100 / (16384-2245)} × (2470/9261) = 0.00377
Expected value of upper dust R = (2/3) × {49 / (16384-2245)} × (4410/9261) = 0.110
Expected value of lower Chile R = (12/3) × {4 / (16384-2245)} × (2205/9261) = 0.00027

Then, the expected value Rt in the “general gaming state in a high-probability bonus” is as follows.
Rt = 0.00062 + 0.00038 + 0.57917 + 0.28621 + 0.00377 + 0.00110 + 0.00027 = 0.87152

  As described above, in the pachislot machine 1 according to the present embodiment, the product of the number of bets per bet (7/3) and the pull-in rate (2646/9261) of the group winning bell winning is multiplied by 1 of the big winning winning of the group winning. Since the multiplied value of the number of payouts per bet (14/3) and the pull-in rate (1323/9261) are set to be equal to each other, the “general gaming state in the normal probability game” and the “general gaming status in the high probability game” The “expected value” of each internal winning combination is set to an approximately equal value.

  Next, each stop table group will be described with reference to FIGS.

  10 to 12 are diagrams conceptually showing a bell winning establishment possible stop table, an all winning combination winning establishment non-achieving stop table, and a big winning prize winning establishment possible stop table among the stop table groups.

  In each stop table, a “stop operation position” and a “stop control position” are shown for each of the left, middle, and right reels 2 to 4. Each numerical value in the “stop operation position” column represents the code number of the symbol positioned on the winning line L1 when each of the stop buttons 31 to 33 is operated. Each numerical value in the “stop control position” column represents a code number of a symbol that is stopped and displayed on the pay line L1 when each stop button 31 to 33 is operated at the corresponding “stop operation position”. For example, in the bell winning establishment possible stop table shown in FIG. 10, when the “stop operation position” of the left reel 2 is the symbol “red 7” of the code number “20”, the “stop control position” is the code number “00”. Since the symbol “bell” is “”, the symbol “bell” is stopped and displayed on the winning line L1. In the present embodiment, the so-called “number of smooth frames” is set to a maximum of 4 frames. For example, when the symbol “watermelon” having the code number “05” is positioned on the winning line L1 while the left reel 2 is rotating, When the stop button 31 is operated, the left reel 2 is controlled to stop so that the symbol “bell” having the code number “09” separated by four frames is stopped on the activated pay line L1.

  In the bell winning establishment possible stop table shown in FIG. 10, the code numbers of “stop control position” for the left reel 2 are “00”, “04”, “09”, “14”, “17”. The code numbers of “stop control position” for the middle reel 3 are “02”, “06”, “10”, “13”, and “18”. The code numbers of “stop control position” for the right reel 4 are “02”, “06”, “10”, “15”, and “19”. These are all code numbers corresponding to the symbol “bell”. That is, when this bell winning establishment possible stop table is used, the symbol “bell” is stopped and displayed on the winning line L1 for each of the left, middle and right reels 2 to 4 regardless of the operation timing of the stop buttons 31 to 33. Thus, the stop control of the reels 2 to 4 is performed, and the winning of “Bell's small role” is always established.

  Further, in the all winning combination winning / losing stop table shown in FIG. 11, the code numbers of the “stop control positions” for the left reel 2 and the middle reel 3 are the same as those in the bell winning establishment possible stop table shown in FIG. It corresponds to “Bell”. However, the code numbers of “stop control position” for the right reel 4 are “03”, “07”, “11”, “16”, and “20”. The code number “03” is the symbol “blue 7”, the code numbers “07” and “20” are the symbol “red 7”, the code number “11” is the symbol “lower dust”, and the code number “16” is the symbol It corresponds to "Upper Chile" respectively. In this case, the symbol combinations aligned on each of the winning lines L1, L2A, L2B, L3A, and L3B do not correspond to any of the internal winning combinations. It will be “losing”.

  In the decisive winning possible stop table shown in FIG. 12, the code number of “stop control position” for the left reel 2 is “00”, “04”, “09”, “14”, “14”, “17” and “12” corresponding to the symbol “upper dust”. Therefore, in the case of the code number “12”, the symbol “upper dust” is stopped and displayed in the middle of the display window 5 and the symbol “lower dust” is stopped and displayed in the lower portion of the display window 5. On the other hand, in the case of code numbers “00”, “04”, “09”, “14”, “17”, “upper dust” and “lower dust” are in the middle and lower rows of the display window 5, respectively. Do not display stop. The code numbers of the “stop control position” for the middle reel 3 are “02”, “06”, “10”, “13”, “18”, all corresponding to the symbol “bell”. is there. The code numbers of the “stop control position” for the right reel 4 are “00”, “04”, “08”, “13”, “17”, and all correspond to the symbol “replay”. is there. For this reason, when the stop table that can establish a winning prize is used, the code numbers of “stop operation position” are “09” to “11” for the left reel 2 that is not hatched in the table. Only in some cases, the symbol “upper chile” is stopped on the winning line L1 and the symbol “lower chile” is stopped on the activated paying lines L2B and L3A. Can be established.

  FIG. 13 is a diagram conceptually illustrating the stop table group selection table.

  The stop table group selection table is a stop table group in which a bell winning can be established as a stop table group when “group role” is drawn as an internal winning combination in “general gaming state in normal probability combination” (see FIG. 10). Or, it is used when selecting any of the winning combination winning / losing stop table group (see FIG. 11). The stop table group selection table stores data for partitioning the extracted random number into each stop table group. Each numerical value in the figure is a lottery value indicating a numerical range in which each stop table group is lottery out of a random number range of “9261” from “0 to 9260”. The lottery value of the stop table group that can win the Bell winning is “2646”, and the lottery value of the stop table group that does not win all the winning combinations is “6615”. The lottery probability of each stop table group is represented by a numerical value having “9261” as a denominator and a lottery value as a numerator.

  The main actuators whose operation is controlled by a control signal from the microcomputer 63 shown in FIG. 4 include a stepping motor 45 that rotationally drives the reels 2, 3, and 4, various lamps (game operation display lamps 13 to 15, start lamps). 17, WIN lamp 19, insert lamp 21), various display units (chance LEDs 9 to 12, stored number display unit 16, bonus count display unit 18, payout number display unit 20), and hopper 72 for storing medals. These are driven by a motor drive circuit 73, each lamp drive circuit 74, each display unit drive circuit 75, and a hopper drive circuit 76, respectively. These drive circuits 73 to 76 are connected to the main CPU 64 via the I / O port 71 of the microcomputer 63.

  As main input signal generating means for generating an input signal necessary for the microcomputer 63 to generate a control signal, the inserted medal sensor 8S for detecting a medal inserted from the medal slot 8 and the operation of the start lever 30 are used. There are a start switch 30S for detecting the stored medal, the aforementioned stored medal insertion switches 26 to 28, and a stored medal settlement switch 29. Furthermore, there is a reel position detection circuit 77 that receives the output pulse signal from the photosensor and detects the rotational position of each reel 2, 3 and 4. The photo sensor is included in the drive mechanism of each reel 2 to 4 and is not shown in the figure.

  The reel position detection circuit 77 counts the number of drive pulses supplied to each of the stepping motors 45 after the rotation of the reels 2 to 4 is started, and writes this count value in a predetermined area of the control RAM 66. Accordingly, the control RAM 66 stores a count value corresponding to the rotation position within one rotation range for each of the reels 2 to 4. The photo sensor generates a reset pulse every time the reels 2 to 4 make 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 by the control RAM 66 is cleared to "0". By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor 45 is eliminated every rotation.

  Further, as the above input signal generating means, a reel stop signal circuit 78 for generating a signal for stopping the 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 are 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. 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 generates a medal payout. Generate a signal to detect completion.

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

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

  As an actuator whose operation is controlled by a control signal from the microcomputer 81, there are reel back lamps 47a, 47b, 47c built in each reel 2-4. Lighting of these back lamps 47 a to 47 c is controlled by a drive signal from a lamp drive circuit 89 connected to the I / O port 87. Further, as the input signal generating means for generating an input signal necessary for the microcomputer 81 to generate a control signal, there are the above-described cross key 23, “◯” button 24 and “×” button 25.

  A VDP (video display processor) 90 and a sound source IC 91 are connected to the I / O port 87. A character ROM 92 storing character data and a video RAM 93 which is a color display display memory are connected to the VDP 90, and an image control program ROM 97 and an image control work RAM 98 are also connected. The VDP 90 displays an image on the liquid crystal display device 22 under the control of the microcomputer 81. The microcomputer 81 fetches information such as the gaming state at that time and the type of winning flag from the main control board 61 via the main control unit communication port 88, and selects an effect image to be displayed based on the fetched gaming state and winning flag. Then, the effect image selected by controlling the VDP 90 is displayed on the liquid crystal display device 22.

  In addition, a sound ROM 94 storing sound data is connected to the sound source IC 91, and the sound source IC 91 emits sound from the speakers 96 and 96 through the power amplifier 95 under the control of the microcomputer 81. The microcomputer 81 controls the sound source IC 91 and the power amplifier 95 in accordance with an instruction input from the main control board 61 via the main control unit communication port 88 to control the medal insertion sound, start lever operation sound, stop button operation sound, bonus Sound effects such as game sounds during the game are output from the speakers 96 and 96. In addition, sound is output from the speakers 96, 96 in a sound output pattern based on the game state fetched from the main control board 61 and an effect mode selected based on the winning flag.

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

  14 to 16 are flowcharts showing an outline of the game process controlled by the main CPU 64 of the main control board 61.

  First, the main CPU 64 performs an initialization process at the start of the game (see step 101 in FIG. 14). In this initialization process, the contents stored in the control RAM 66 are initialized, the communication data is initialized, and the like. Subsequently, a RAM clear process at the end of the game is performed (step 102). Specifically, the data in the writable area of the control RAM 66 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the control RAM 66, and the start address of the sequence program of the next game is set. Make designations.

  Next, the main CPU 64 determines whether or not there is a request for automatic medal insertion, that is, whether or not a replay winning is established in the previous game (step 103). When a replay winning is established, medals for the insertion request are automatically inserted (step 104). On the other hand, when the replay winning is not established, it is determined whether or not there is a medal insertion (step 105). Specifically, it is determined whether or not there is an input from the inserted medal sensor 8S or the stored medal insertion switches 26, 27, and 28. If no medal has been inserted, the process returns to step 103 and the above-described process is repeated. On the other hand, when there is an automatic insertion of medals or insertion of medals, the main CPU 64 determines whether or not there is a start signal input from the start switch 30S based on the operation of the start lever 30 (step 106). If there is no start signal input, the process of step 106 is repeated. On the other hand, if a start signal is input, it is next determined whether 4.1 seconds have elapsed since the previous game (step 107). If 4.1 seconds have not elapsed, the game function waits until 4.1 seconds have elapsed after the wait function is activated (step 108). As the waiting time is consumed, a wait time command is transmitted to the sub-control board 62 side via the I / O port 71. If the operation of the start lever 30 is performed before the elapse of 4.1 seconds, a non-reelable sound is emitted from the speakers 96, 96, and the player is notified that the weight function has been activated.

  When 4.1 seconds have elapsed since the previous game, reel rotation processing is performed (step 109). In the reel rotation processing, 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 the rotation of the reels 2 to 4, and each reel 2 to 4 is subsequently stepped. The motor 45 is rotationally driven. Next, a random number for lottery generated by the random number generator 69 is extracted by the sampling circuit 70 (step 110), and then a game monitoring timer for counting the above 4.1 seconds is set (step 110). 111). Subsequently, the main CPU 64 performs a gaming state monitoring process (see FIG. 15, step 112), a probability lottery process (step 113), a high-probability actor control process (step 114), and a stop table group selection process (step 115). )I do. After these processes are performed, a game start command transmission process is performed (step 116). In the game start command transmission process, a game start command is transmitted to the sub-control board 62 side via the I / O port 71 based on the start signal input from the start switch 30S to the main CPU 64. The game start command includes a 16-bit parameter representing the internal winning combination and the gaming state.

  Next, it is determined whether or not any of the stop buttons 31 to 33 has been turned on (step 117). If it is not turned on, it is determined whether or not the value of the automatic stop timer has become 0 (step 118). The automatic stop timer is for automatically stopping the reels 2 to 4 after a predetermined time has elapsed when the stop buttons 31 to 33 are not operated for a predetermined time.

  If any one of the stop buttons 31 to 33 is turned on or the automatic stop timer reaches 0, the number of symbols to be drawn on the activated pay line, that is, the number of sliding frames is determined (step). 119). The number of sliding symbols is determined from the gaming state, winning request, number of control symbols, symbol position, etc. If the number of frames from the activated winning line to the winning symbol is within the range of control symbols, it is determined as the number of sliding symbols. The 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 stop request flag being set, reel pull-in control is performed in which the first stop reel is rotated by the determined number of sliding frames. The rotation of the reels is stopped (step 120). When the rotation of the reels stops, a reel stop command is transmitted to the sub-control board 62 side via the I / O port 71 (step 121). This reel stop command is configured to include a 16-bit parameter indicating which of the reels 2 to 4 on the left, middle and right reels whose rotation has stopped.

  Next, it is determined whether or not all the reels 2 to 4 are stopped (step 122). If the second stop reel and the third stop reel have not stopped yet, the process returns to step 117 and the above processes are repeated. When all the reels 2 to 4 are stopped, the main CPU 64 performs a winning search process (see step 123 in FIG. 16). In this winning search process, the type of combination of symbols actually arranged on the activated winning line is matched with the type of the internal winning combination determined by the probability lottery process. Next, it is determined whether or not the winning flag is normal (step 124). When the determination result is not normal, for example, when the combination of watermelon symbols is aligned on the activated pay line, but the winning request flag corresponding to the internal winning combination is a replay flag, the payout display unit 20 Then, an illegal error is displayed on the liquid crystal display device 22 (step 125). If the winning flag is normal, the game medal is stored or paid out according to the state at that time (step 126). In other words, if a game is being played with credit, the number of stored coins displayed on the credit display unit 16 is increased by the number of medals acquired by winning, and the game is played by inserting a medal into the medal slot 8. If it is in a state of being performed, the number of medals won by winning is paid out to the medal tray 34.

  When the medal is stored or paid out, a winning command is transmitted to the sub-control circuit 62 side via the I / O port 71 (step 127). The winning command includes a 24-bit parameter representing a winning combination, a gaming state, and a winning line. Next, it is determined by the main CPU 64 whether or not the current gaming state is “BB general gaming state” or “RB gaming state” (step 128). If it is not in the “BB general gaming state” or “RB gaming state”, a BB / RB winning check process is performed (step 129). In this BB / RB winning check process, it is determined whether a BB or RB winning has been established. When the BB winning is established, the gaming state is shifted to the “BB general gaming state”, and when the RB winning is established, the gaming state is shifted to the “RB gaming state”. Subsequently, the game processing by the main CPU 64 returns to step 102, and the next new game is started. On the other hand, if the game state is “BB general game state” or “RB game state” in step 128, the number of games in the BB game or RB game is checked by the main CPU 64 (step 130). Subsequently, the main CPU 64 determines whether or not the current gaming state is at the end of the BB game (step 131). If the BB game is over, then the RAM clear process at the end of the BB game is performed on the control RAM 66 (step 132), and the BB end command is sent to the sub-control circuit 62 side via the I / O port 71. Sent. The BB end command includes a 3-bit parameter indicating the end operation. Thereafter, the game process returns to step 102 and the next new game is started. If it is determined at step 131 that the BB game has not ended, the game process returns to step 102 and the next new game is started.

  Next, the gaming state monitoring process performed in step 112 of FIG. 15 will be described.

  FIG. 17 is a flowchart showing details of the gaming state monitoring process. In the gaming state monitoring process, first, the main CPU 64 determines whether or not the gaming state is the “BB general gaming state” or the “RB gaming state” (see FIG. 17, step 201). If the gaming state is “BB general gaming state” or “RB gaming state”, the gaming state is set according to the type of each gaming state (step 202), and the gaming state monitoring process is terminated. On the other hand, when the gaming state is not “BB general gaming state” or “RB gaming state” in step 201, it is determined whether or not the high probability bonus flag is ON (step 203). If the high-probability character flag is ON, the game state is set to “high-probability character general game state” (step 204). On the other hand, if the flag in the high probability combination is not ON in step 203, the gaming state is set to "general gaming state in normal probability combination" (step 205). After the game state is set to “general game state in normal probability game” or “general game state in high probability game”, the game state monitoring process ends.

  Next, the probability lottery process performed at step 113 in FIG. 15 will be described.

  FIG. 18 is a flowchart showing details of the probability lottery process. In the probability lottery process, first, the main CPU 64 sets a probability lottery table of a type corresponding to the gaming state set in the gaming state monitoring process in the control RAM 66 (see step 301 in FIG. 18). For example, when the gaming state is “general gaming state in high-probability bonuses”, the probability lottery table for general gaming status in high-probability bonuses (see FIG. 6B) is set in the control RAM 66 and “normal” In the case of “general gaming state in probable role”, the probability lottery table (see FIG. 6A) for the general gaming state in normal probability role is set in the control RAM 66. Subsequently, based on the set probability lottery table and the number of inserted medals, the internal winning combination lottery is performed (step 302). In this lottery, a random number for lottery generated by the random number generator 69 is extracted by the sampling circuit 70, and the extracted random number value belongs to which internal winning combination in the probability lottery table set in the control RAM 66. It is done by judging. Next, the main CPU 64 stores the lottery information of the internal winning combination in the control RAM 66 (step 303), and ends the probability lottery process.

  Next, the high-probability accessory control process performed in step 114 of FIG. 15 will be described.

  FIG. 19 is a flowchart showing details of the high-probability accessory control process. In the high-probability actor control process, first, the main CPU 64 determines whether or not the gaming state is the “general gaming state” (see step 401 in FIG. 19). If the gaming state is not the “general gaming state”, the high-probability accessory control process is terminated as it is. On the other hand, if the gaming state is the “general gaming state”, the main CPU 64 next determines whether or not the high-probability bonus item flag is ON (step 402). If the high-probability-object-in-progress flag is ON, a high-probability-object-end lottery table (see FIG. 8) is set in the control RAM 66 (step 403). On the other hand, if the high probability combination flag is not ON, the high probability combination start lottery table (see FIG. 7) is set in the control RAM 66 (step 404). Next, random numbers for lottery are extracted (step 405), and lottery based on each lottery table set in the control RAM 66 is performed (step 406). Subsequently, the main CPU 64 determines whether or not the lottery result is a win (step 407). This determination is performed by determining whether the random value extracted in step 405 belongs to a winning or non-winning section of each lottery table. If the lottery result is a win, the high-probability medium flag is reversed (step 608). In other words, if you win a lottery based on the lottery table based on the end of the high-probability feature, turn off the flag in the high-probability bonuses, and if you win a lottery based on the lottery table that starts the high-probability feature, Turn on the middle flag. On the other hand, if the lottery result is not a win in step 407, the high-probability accessory control process is terminated without reversing the high-probability accessory flag.

  Next, the stop table group selection process performed in step 115 of FIG. 15 will be described.

  FIG. 20 is a flowchart showing details of the stop table group selection process. In the stop table group selection process, first, the main CPU 64 determines whether or not the gaming state is a “general gaming state in a high-probability accessory” (see step 501 in FIG. 20). This determination is made by determining whether or not the high-probability character medium flag is ON. If the gaming state is not the general gaming state in the high probability combination, then the main CPU 64 determines whether or not the internal winning combination lottery in the probability lottery process (see step 113 in FIG. 15) is a “group combination”. Is determined (step 502). When the internal winning combination is “group combination”, a stop table group selection table (see FIG. 13) is set in the control RAM 66 (step 503), and a random number for lottery is extracted (step 504). Next, the main CPU 64 performs a lottery based on the stop table group selection table set in the control RAM 66 (step 505), and determines whether the result of the lottery is a win for the stop table group that can be established as a bell prize (step 506). ). The determination of the lottery result is performed by determining which lottery value section of the stop table group selection table belongs to the random value extracted in step 504. If the lottery result belongs to the lottery value section assigned to the bell winning establishment possible stop table group and is a win, the bell winning establishment possible stop table group is selected and set in the control RAM 66 (step 507). . On the other hand, if the lottery result is not a win, the all winning combination winning / losing stop table group is selected and set in the control RAM 66 (step 508). Also, if the determination result in step 501 is not a general game state with a high-probability role, or if the determination result in step 502 is not “group role”, a stop table group corresponding to the internal winning combination and game state is set. This is selected and set in the control RAM 66 (step 509), and the stop table group selection process is terminated.

  Thus, according to the pachislot machine 1 of the present embodiment, when the “group role” internal winning combination is drawn in the probability lottery process of FIG. 20. In the lottery based on the stop table group selection table in step S505, either the stop table group that can make a Bell winning combination or the stop table that does not win all winning combinations is selected. In FIG. 20, when the stop table group that can establish the bell winning is selected in step 507, the combination of the symbol “bell” is stopped and displayed on the activated winning line regardless of the operation timing of the stop buttons 31 to 33 by the player. The winning of “Bell's small role” is always established. On the other hand, when the all winning winning / not winning stop table group is selected in FIG. 20, step 508, no winning of any internal winning combination can be established no matter what timing the stop buttons 31 to 33 are operated. . On the other hand, when the “group role” internal winning combination is drawn in the probability lottery process of FIG. 15 and step 113 in “general gaming state in high probability combination”, the stop table that can establish a big prize winning is selected in FIG. 20 and step 509. The symbols “Upper Chile” and “Upper Chile” and “ The combination of “Lower Chile” is stopped and the winning of “Decachiri Minoru” is established.

  In other words, when “group role” is drawn as an internal winning combination in “general gaming state in high probability combination”, the player aims at symbols “upper chilli” and “lower chilli” and stops buttons 31 to 31 33 has to be operated. A skilled person who can operate the stop buttons 31 to 33 at a predetermined timing when the symbols “upper chilli” and “lower chilli” are drawn into the activated pay line can obtain many medals. On the other hand, a beginner who is difficult to operate the stop buttons 31 to 33 at the predetermined timing cannot obtain so many medals. Accordingly, the player's skill is reflected in the number of medals obtained from the conventional pachislot machine. For this reason, the player operates the stop buttons 31 to 33 at a predetermined timing to enter the “group role” in an interest of being able to enjoy a lot of SB winnings in the “general gaming state in the high-probability game” and enjoy the feeling of consecutive wins. An interest that can win many medals will be added. In addition, since the symbols “Upper Chile” and “Lower Chile” are within the range of the number of sliding symbols of the symbol “Blue 7”, the symbol “Upper Chile” or “Lower Chile” when the SB is drawn as an internal winning combination When the stop button 31 is operated while is positioned on the activated pay line, the symbol “blue 7” is drawn into the activated pay line. For this reason, it is possible to eliminate the loss of SB as long as it is aimed at “a small role of big spot”.

  In addition, when “group role” is drawn as an internal winning combination, depending on whether the game state is “general game state in normal probability game” or “general game state in high probability game” Since the types of symbols to be arranged on the activated pay line and the operation timing of the stop buttons 31 to 33 are different, the game can be made diverse, and this point also enhances the interest of the game. As a result, the player can feel fun by playing the game.

  In addition, the “expected value” indicating the payout per unit bet of medals is almost equal for the “group role” in the “general game state in the normal probability game” and the “general game state in the high probability game”. The expectation of the payout amount that can be obtained by the player in each of these gaming states can be made substantially equal. For this reason, the game store can make the amount of medals that can be acquired by all the players through each gaming state constant while allowing a skilled player to acquire a large number of medals.

  In the description of the above embodiment, when one internal winning combination “Decachiri Minoru” constituting “Group combination” is drawn, one decachiri winning establishment stop table that needs to be paid The stop control of the reels 2 to 4 was performed using only the group. However, there are two types with different “retraction ratios” so that the “expected value” of “Dekachiri Minoru” and “Bell Minoru” constituting “Group” are almost the same value. If a “group role” is drawn in the “high-probability general game state” lottery, select one of the two tables by lottery. And may be used. For example, a stop table group A having a “draw-in rate” of “1320/9261” and a stop table group B having a “draw-in rate” of “1326/9261” are provided as stop table groups capable of establishing a big winning prize. Any table group may be selected with a probability of 2 ″. In this case, the value of “retraction ratio” ((1320/9261 + 1326/9261) × 1/2) as the whole “deciduous small part” is a value (1323) when the stop table group that can be established as a big winning prize is used. / 9261), and each “expected value” of “bell's small role” and “decachile's small role” constituting “group role” can be made substantially equal. Even with this configuration, it is possible to reflect the player's skill in the number of medals earned, and in addition, the “group role” in the “general game state in high probability game” and “general game state in normal probability game” Since the type of symbol that establishes the prize and the operation timing of the stop buttons 31 to 33 are different, it is possible to give diversity to the game, and the player can feel the game more interesting.

  Further, in the above embodiment, the number of dividends for “Decachiri Minoru” (14) is set to double the number of dividends for “Bell Minoru” (7). If the “expected value” of the combination is almost equal, the number of dividends for each internal winning combination is arbitrary and may be changed as appropriate. For example, it is assumed that the number of payouts is the same value for “deciduous small part” and “bell small part”, and the probability that a stop table group that can be established for winning a bell is selected in the stop table group selection process (see FIG. 20) (2646 / 9261) may be set to be the same as the value (1323/9261) of the “pull-in rate” in the stop table group where the big winning prize can be established. In the above embodiment, the case where the special game is the SB game has been described. However, the present invention is not limited thereto, and the special game may be applied as a BB game, an RB game, or a specific small role. Even in this case, as in the above embodiment, the player can feel fun by playing the game.

  Further, in the above embodiment, the lottery for the occurrence or the end of the “high-probability medium general gaming state” is performed in all games. However, it is not always necessary to perform these lotteries in all games. For example, when a specific internal winning combination is drawn or won, these lotteries may be performed. In the above embodiment, the “general gaming state in a high-probability bonus” is generated or terminated by lottery using a table. However, the conditions for generating and ending the “general gaming state in the high-probability role” are arbitrary. For example, the “general gaming state in the high-probability role” may be ended by digesting the specified number of games. . In addition, the lottery probability of each internal winning combination is also set to at least equal to the “expected value” for “group role” in “general game state in normal probability game” and “general game state in high probability game”. It is optional if it can be maintained. For example, the lottery probability of “SB” in the “general gaming state in the high-probability role” is arbitrary as long as it is higher than the lottery probability of “SB” in the “general gaming state in the normal probability role”. It can be changed as appropriate. Further, the combination of the small combinations constituting the “group combination” is arbitrary, and may be appropriately changed according to the types of symbols represented on the symbol columns of the left, middle, and right reels 2 to 4.

  In the above embodiment, among the “group role”, the “decachiri small role” can be established in the “high probability role general game state”, and the “bell small role” is set as the “normal probability role normal game” In the “state”, the winning can be established. However, “Bell's small role” may be established in the “high-probability role general game state”, and “Decachiri's small role” may be established in the “normal probability character's general game state”. Further, in the above-described embodiment, the case where the reels 2 to 4 in which the symbol row is expressed on the outer periphery is used as the fluctuation display unit has been described. However, an image display device such as a liquid crystal display device may be used as the variable display means.

  Further, in the above embodiment, when the “group role” is internally won in the “high-probability medium general gaming state”, if the stop buttons 31 to 33 are operated at a predetermined timing, the “decidile small role” It was assumed that the prize was won. However, for example, when the stop buttons 31 to 33 are operated in a predetermined pressing order, a winning of a predetermined small combination such as “a small combination small combination” may be established. In this case, it is preferable that the “expected value” for at least the “group combination” is substantially the same in the “general gaming state in the normal probability combination” and the “general gaming state in the high probability combination”. Further, when a predetermined condition is satisfied, the above-described predetermined pressing order may be notified, and so-called missing may be excluded. Thereby, the player can establish a prize for a predetermined small role such as “a small role of a big spot” without needing to push.

  Further, in the above embodiment, when the “group role” is internally won in the “general gaming state in the normal probability combination”, the stop table group that can win the Bell winning combination or the all winning combination winning stoppage table group is selected by lottery, An explanation has been given of a case in which a stop table group in which a big winning combination can be established is selected when the “group role” is elected internally in “general gaming state in high probability combination”. However, when the “group role” is won internally in each of these gaming states, a stop table group that can establish a bell winning prize or a stop table group that can establish a big winning prize may be selected by lottery. For example, if the “group role” is elected internally in the “general gaming state in the normal probability game” or the “general gaming state in the high probability game”, the stop table group that can win the bell prize or the stop table group that can win the big prize game is drawn. In the `` general gaming state in the normal probability game '', the lottery probability of the stop table group that can win the Bell prize is set to a value that is higher than or equal to the lottery probability of the stop table group that can win the Big Prize game. In the “general gaming state”, the lottery probability of the stop table group capable of achieving the Bell winning prize may be set to a value lower than or equal to the lottery probability of the stop table group capable of establishing the big prize winning. According to this configuration, the stop table group that can establish a winning big prize may be used in both the “general gaming state in the normal probability game” and the “general gaming status in the high probability game”, Opportunities to operate the stop buttons 13 to 33 aiming at the symbol combination corresponding to the “comb” are increased, so that the player's skill can be more reflected in the number of game media acquired.

  Further, in the above-described embodiment, the case where only one type of “general gaming state in high-probability bonuses” is provided has been described. However, for example, a plurality of types of “general gaming state in high-probability actors” with different end conditions are provided, and the duration of each “general gaming state in high-probability bonus” is different, and continues for a relatively long time. The “general gaming state in a high-probability role” and the “general gaming state in a high-probability role” that lasts for a relatively short time may occur. Also, a plurality of types of “general gaming state in high-probability actors” with different start conditions may be provided. In addition, when the number of games that BB has not won internally reaches a predetermined number of games, in the pachislot machine that shifts the gaming state to a bonus game advantageous to the player, the predetermined game as a condition for shifting to the bonus game There may be provided a plurality of types of “general gaming state in a high-probability accessory” having different numbers, so-called ceiling setting conditions, and different transition conditions between them. According to such a configuration, it is possible to provide a difference in the period during which the player is in an advantageous state (or an unfavorable state), and the fun of the game is improved.

  Further, in the above embodiment, when the bell winning possible stop table group is selected, the bell winning is surely established regardless of the operation timing and operation sequence of the stop buttons 31 to 33. Depending on the operation timing and operation sequence of the stop buttons 31 to 33, a place where the “bell small part” winning is not established may be provided to give a slight technical intervention.

  In the above embodiment, the case where the gaming machine according to the present invention is applied to a pachislot machine has been described. However, the present invention is applied to a ball game machine such as a pachinko machine that stops the change display of the reels according to the stop operation of the player. It is also possible to do. Even when the present invention is applied to such a gaming machine, the same effects as the above-described embodiment can be obtained.
