Description

  The present invention relates to a gaming machine such as a pachinko machine, and more particularly to a gaming machine that gives a specific gaming state advantageous to a player when the result of a symbol variation game is a specific result.

  In conventional gaming machines, when starting a symbol variation game that is a big hit, various settings are made at the start of variation based on the type of jackpot symbol displayed. For example, when the result of the symbol variation game is a big hit, it is determined whether or not the big hit symbol is an odd number (that is, whether the symbol is a trigger for starting the special symbol probability fluctuation), and the determination result is There has been disclosed a gaming machine that selects different variation patterns depending on the situation (see Patent Document 1).

In recent years, in addition to the above-mentioned processing, a combination of processing for determining the number of times of opening the special electric accessory, that is, processing for determining the number of times of opening of the big winning opening in the jackpot gaming state (rounds), etc. Due to the tendency to set, the number of processes performed at the start of fluctuation is increasing. For example, probability variation big hit (probability big hit), non-probability big hit (normal big hit that does not become a probability variation), short open positive change big hit (probable big hit with a short opening time of the big prize opening, so-called sudden probability change), short open big hit There is disclosed a gaming machine in which four types of big hits (a big hit with a short opening time of the big prize opening) are set (see Patent Document 2). In addition, a gaming machine in which more various jackpots are set has also been proposed by involving a process after the jackpot (a process for determining whether or not to start normal symbol probability fluctuation).
JP 2006-34789 A ([0152], FIG. 29, etc.) JP 2006-14845 A (FIG. 4 etc.)

  By the way, various processes performed at the start of fluctuation in the case of a big hit (a process for setting a fluctuation pattern distribution table, a process for determining whether or not to give a special symbol probability fluctuation, a process for setting the number of times of opening a special electric accessory) In the process of determining whether or not to add the normal symbol probability variation, etc., one option is usually selected from a plurality of options based on the jackpot symbol. In addition, the above-mentioned various processes include “a process for determining whether or not to give a variable time reduction (so-called short time)” and “a process for setting an opening effect time (opening time) for informing the start of a big hit gaming state”. , “Process to set round interval time (time between each round in jackpot gaming state)”, “Process to set end time (ending time) to notify the end of jackpot gaming state”, etc. There is.

  Selection of options in such various processes is performed by main control means for controlling the entire gaming machine. This main control means must make a determination based on a program having a number of data that is, for example, a multiple of the number of types of jackpot symbols each time each process is performed. As a result, the data capacity of the program used for determination increases, and the burden on the main control means increases. In particular, in recent years, there is a tendency for the number of special symbols to be set and the game status after the big hit to be hard to grasp from the displayed special symbols, so the data capacity tends to increase more and more. Since the means has a data capacity limitation, the above problem becomes more prominent. Therefore, it is required to reduce the data capacity as much as possible.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine that can reduce the burden on the game control means by simplifying symbol determination and reducing the data capacity. is there.

In order to solve the above-mentioned problem, in claim 1, based on the winning of a game ball at the start winning opening, a symbol variation game that varies a plurality of types of special symbols, and a plurality of types determined based on the special symbols In a gaming machine provided with a game control means for performing a symbol combination game in which the design symbols of the above are varied in a plurality of columns, and providing a specific gaming state advantageous to the player when the result of the symbol variation game is a specific result, The plurality of types of special symbols exist for each type of specific result, and the plurality of types of special symbols include a variation pattern type that is a base of the symbol combination game, and after the end of the specific gaming state. and information indicating whether or not to grant the special game state is associated, said game control means includes a main control unit for controlling the whole gaming machine, control from the main control means command And a sub-control means for performing control to execute the game effects based on, the main control unit includes a specific result determination means for determining whether the symbol variable game result is a particular result, the specific results when the symbol variable game result is determined to be a particular result by the determining means, based on a random number value extracted by the random number lottery, one special symbol indicating a specific result among a plurality of types of the special symbol A symbol selection means for selecting, and a game content determination process executing means for executing a plurality of game content determination processes for determining game content, wherein the sub-control means is configured to execute the game based on the special symbol selected by the symbol selection means. determine the performance symbol, the game content determination process executing means, in a plurality of the game content determination process, based on the special symbol selected by said pattern selecting means , Symbol set and choices selecting means for selecting one option from a plurality of choices which is set in advance, when the combination of the selected choice have multiple special symbols equal, a common design type for those special symbol The gist of the gaming machine is characterized by comprising a type setting means and executing a plurality of the game content determination processes using the symbol type set by the symbol type setting means.

  Therefore, according to the first aspect of the present invention, when there are a plurality of symbols having the same combination of choices, the symbol type setting means sets a common symbol type for these symbols. That is, a plurality of symbols having the same combination of options are grouped into one group, and a common symbol type is set for the plurality of symbols belonging to the group. For this reason, the number of symbol types is smaller than the number of symbols selected by the symbol selecting means. As a result, the game content determination processing execution means can execute a plurality of game content determination processes using a smaller number of symbol types than the symbol selected by the symbol selection means, so the data capacity of the program used for each game content determination process is reduced. This can reduce the burden on the game control means. It should be noted that as the number of symbol types increases, the burden on the game control means can be more effectively reduced by setting the symbol type by applying the present invention.

  As a specific result, the result of the symbol variation game is a big hit. When the specific result is a big hit, the specific game state is a big hit game effect (a big hit game state) started after the symbol variation game that is a big hit.

  As the game content determination process, a variation pattern selection process for selecting one variation pattern from a plurality of variation patterns as a base of the symbol variation game (Claim 3), a special game state is given after the end of the specific gaming state Special game state determination process for determining whether or not to perform (Claim 3), and a specific game state selection process for selecting one specific game state from a plurality of specific game states when determining the specific game state (Claim) 3).

  In addition, when there are a plurality of symbols having the same combination of choices selected in the plurality of game content determination processes, a method for setting a common symbol type for these symbols includes the following. As an example, there are four types of symbols A, B, C, and D, three types of game content determination processing are game content determination processings 1, 2, and 3, and an option selected in the game content determination processing 1 is option A1 , A2, the choices selected in the game content determination process 2 are the two options B1 and B2, and the choices selected in the game content determination process 3 are the choices C1 and C2. . For example, based on the symbols A and D, when the option A1 is selected in the game content determination processing 1, the option B1 is selected in the game content determination processing 2, and the option C1 is selected in the game content determination processing 3, the symbols A, A common symbol type 1 is set for D. On the other hand, if the option A2 is selected in the game content determination process 1, the option B2 is selected in the game content determination process 2, and the option C2 is selected in the game content determination process 3 based on the symbols B and C, A common symbol type 2 is set for C.

  Here, “setting the symbol type” means, for example, temporarily setting a flag corresponding to the symbol type, and specifically “0”, “1”, “2” in a specific storage area. It means that a numerical value indicating a flag such as is temporarily stored.

Claim 2 is based on the winning of a game ball at the start winning opening, the symbol variation game for varying a plurality of types of special symbols, and the plurality of types of effect symbols determined based on the special symbols are varied in a plurality of columns. In the gaming machine provided with a game control means for giving a specific gaming state advantageous to a player when the result of the symbol variation game is a specific result, the plurality of types of special symbols are: It exists for each type of specific result, and whether or not to give a special game state to the plurality of types of special symbols, the type of variation pattern that is the base of the symbol combination game, and after the end of the specific game state and information associated indicating whether the game control means, is executed and the main control unit for controlling the whole gaming machine, game effects based on a control command from the main control unit And a sub-control means for controlling that, the main control unit includes a specific result determination means for determining whether the symbol variable game result is a particular result, the symbol variation game by the identification result determining means When it is determined that the result is a specific result, based on the random value extracted by random number lottery, a symbol selecting means for selecting one special symbol indicating the specific result from the plurality of types of special symbols, A game content determination process executing means for executing a plurality of game content determination processes for determining game content, and the sub-control means determines the effect symbol based on the special symbol selected by the symbol selection means, multiple game content determination process executing means, which in a plurality of the game content determination process, based on the special symbol selected by said pattern selecting means, preset And choice selection means for selecting one option from a selection, when there are a plurality of symbols groups combination of the selected option consists of equal plurality of special symbols, the symbol classification setting means for setting a different pattern types for each symbol group The gaming machine is characterized in that a plurality of the game content determination processes are executed using the symbol type set by the symbol type setting means.

  Therefore, according to the second aspect of the present invention, when there are a plurality of symbol groups composed of a plurality of symbols having the same combination of choices, the symbol type setting means sets a different symbol type for each symbol group. That is, a plurality of symbols having the same combination of options are grouped into one symbol group, and a common symbol type is set for the plurality of symbols belonging to the symbol group. For this reason, the number of symbol types is smaller than the number of symbols selected by the symbol selecting means. As a result, the game content determination processing execution means can execute a plurality of game content determination processes using a smaller number of symbol types than the symbol selected by the symbol selection means, so the data capacity of the program used for each game content determination process is reduced. This can reduce the burden on the game control means. It should be noted that as the number of symbol types increases, the burden on the game control means can be more effectively reduced by setting the symbol type by applying the present invention.

Fluctuation pattern of the invention according to claim 3, in claim 1 or 2, a plurality of the game content determination process in which the game content determination process executing means for executing, for selecting one of variation patterns from a plurality of the fluctuation pattern selection process, wherein the special game state determination process of determining whether or not to grant the special game state after completion of the specific game state, and, when applying the specific game state, one identified from a plurality of specific game state The gist of the invention is that two or more processes are selected from the specific game state selection process for selecting the game state.

  Therefore, according to the third aspect of the present invention, the game content determination processing execution means uses a smaller number of symbol types than the symbol selected by the symbol selection means, and the variation pattern selection processing, special game state determination processing, and identification Two or more processes selected from the game state selection process can be executed. Thereby, since the data capacity of a program can be reduced by each process, the burden concerning a game control means can be reduced more effectively.

  The plurality of game content determination processes are preferably composed of as many processes as possible. This is because the more content the game content determination process has, the more effectively the burden on the game control means can be reduced when a plurality of game content determination processes are executed based on the symbol type. The plurality of game content determination processes may include a variation pattern selection process that is an essential process when a symbol variation game is performed.

  Here, as the variation pattern selection processing, processing for selecting one variation pattern distribution table from a plurality of variation pattern distribution tables, or one variation pattern from a plurality of variation patterns allocated to the variation pattern distribution table. The process of selecting is included.

  Note that the special gaming state in which it is determined whether or not to be granted in the special gaming state determination process includes a special symbol probability variation (so-called probable variation) in which the jackpot lottery probability varies with a high probability. Also, as a special game state, the normal symbol probability variation in which the probability that the normal symbol will stop with the winning symbol combination fluctuates with high probability, the mini digital (ordinary symbol) variation time is shortened, and the electric tulip (electric chew) Examples include shortening the normal symbol variation time to increase the frequency of opening, and shortening the special symbol variation time in which the variation time of the main digital (special symbol) is shortened. Therefore, the special gaming state determination process includes a process for determining whether or not to give a special symbol probability variation, a normal symbol probability variation, a normal time variation time reduction, a special symbol variation time reduction, and the like.

Further, the specific game state selected in the specific game state selection process includes the number of times of opening of the big prize opening (number of rounds) in the big hit game state, the opening effect for informing the start of the big hit game state, An interval effect executed between rounds, an ending effect for informing the end of the big hit gaming state, and the like can be given. Therefore, the specific game state selection process includes a process of setting the number of rounds. Further, the specific game state selection process includes a process of setting the contents and time of an opening effect, an interval effect, and an ending effect.
According to a fourth aspect of the present invention, in the third aspect, the game content determination process includes a special winning opening state selection process for selecting one specific gaming state from a plurality of specific gaming states in which the number of opening of the large winning opening is different. Special symbol variation time shortening determination process for determining the special symbol variation time reduction, Normal symbol variation time shortening determination process for determining the regular symbol variation time reduction, Opening effect time selection process for selecting the opening effect time, Interval effect The gist of the present invention further includes at least one of an interval effect time selection process for selecting the time of the ending effect and an ending effect time selection process for selecting the time of the ending effect.

The invention according to claim 5 is the symbol number table in which the symbol number for identifying the symbol is listed in any one of claims 1 to 4 and the symbol type number for identifying the symbol type is listed. The symbol selection number is determined based on the random number value, and the symbol selection number is determined based on the random number value, and the symbol number is located in the determined allocation order. The symbol type setting means determines from the symbol type number table the symbol type number located at the same location as the arrangement order determined by the symbol selection means, and the symbol type determination unit determines the symbol type The gist is to set the symbol type with reference to the number.

Therefore, according to the fifth aspect of the present invention, the symbol selecting means selects a symbol by referring to data designated by a random number value from the symbol number table in which symbol numbers are listed. On the other hand, the symbol type setting means sets the symbol type by referring to the data designated by the symbol number arrangement order from the symbol type number table in which the symbol type numbers are listed. That is, the symbol selection means and the symbol type setting means specify one value (symbol, symbol type) by the same method, so that the design of the game control means is not complicated.

As described in detail above, according to the first to fifth aspects of the present invention, it is possible to provide a gaming machine that can reduce the burden on the game control means by simplifying the symbol determination and reducing the data capacity. Can do.

In particular, according to the invention described in claim 5 , the design of the game control means is not complicated.

Normal reach means that in the above-mentioned production symbol E1 (left symbol, right symbol, middle symbol), the left symbol and right symbol are stopped at the same symbol, the middle symbol is changed, and then the symbol symbol combination is stopped. An effect that leads to Superreach refers to an effect in which, for example, a special effect is performed in a state where the left symbol and the right symbol are stopped at the same symbol, and after the middle symbol is changed, the symbol combination is stopped and the symbol combination is derived. That is, the fluctuation patterns P1, P2, P5, P6, P9, and P10 are patterns that serve as a base for the jackpot effect in which the middle symbol stops at the same symbol as the left symbol and the right symbol in the case of normal reach 1 to 6. ing. Further, the fluctuation patterns P3, P4, P7, P8, P11, and P12 are patterns that become the base of the jackpot effect in which the middle symbol stops at the same symbol as the left symbol and the right symbol after developing to super reach 1-6. Is shown. It should be noted that the appearance rates of super reach 1-6 (probability of changing patterns P3, P4, P7, P8, P11, P12) are the same as the appearance rates of normal reach 1-6 (change patterns P1, P2, P5, P6). (Probability of selecting P9 and P10). In addition, the super reach 1-6 has high reliability which becomes a big hit compared with the normal reach 1-6. Also, the time for the big hit effect (symbol variation time) varies for each of the variation patterns P1 to P12.

  The main ROM 31b shown in FIG. 4 stores a loss variation pattern distribution table (see FIG. 13). The variation patterns P13 to P17 are distributed in the loss variation pattern distribution table. The variation patterns P13 to P17 are classified into a variation pattern P13 for loss effect and a variation pattern P14, P15, P16, P17 for loss reach effect. The variation pattern distribution random numbers are distributed to the variation patterns P13 to P17. Each variation pattern P13 to P17 is associated with the time and content of the game effect. Here, the fluctuation patterns P14 and P15 indicate patterns for normal reach 7 and 8, and the fluctuation patterns P16 and P17 indicate patterns for super reach 7 and 8, respectively. The variation pattern P13 indicates a pattern that serves as a base for a loss effect (normal variation) for deriving a loss symbol combination (a symbol combination from which a symbol combination that is a big hit or reach is not derived). Fluctuation patterns P14 and P15 indicate patterns that serve as a base for a lost reach effect in which the middle symbols stop at a symbol different from the left symbol and the right symbol in the case of normal reach 7 and 8. Fluctuation patterns P16 and P17 indicate patterns that become the base of the lost reach effect in which the middle symbol stops at a symbol different from the left symbol and the right symbol after developing to super reach 7 and 8, respectively. Note that the appearance rate of the super reach 7 and 8 (probability of selecting the variation patterns P16 and P17) is lower than the appearance rate of the normal reach 7 and 8 (probability of selecting the change patterns P14 and P15). Further, the time for the lost effect and the lost reach effect (symbol variation time) is different for each variation pattern P13 to P17.

  Next, various processes related to the symbol combination game executed by the main CPU 31a (such as jackpot determination, reach determination, jackpot symbol, lost symbol, variation pattern determination, etc.) will be described. The main ROM 31b shown in FIG. 4 stores programs (specific result determination program, symbol selection program, game content determination processing execution program, symbol type setting program, etc.) used for the various processes described above.

  The specific result determination program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “specific result determination means”. That is, the main CPU 31a determines whether or not the result of the symbol variation game (and the result of the symbol combination game) is a big hit. More specifically, the main CPU 31a reads out the jackpot determination random number value and the jackpot symbol random number value updated at predetermined intervals from the main RAM 31c, triggered by the establishment of the start winning condition, and those values. Is stored (stored) in a random number storage area of the main RAM 31c. Then, immediately before the start of the symbol combination game, the main CPU 31a compares the jackpot determination random number stored in the random number storage area of the main RAM 31c with the jackpot determination value stored in the main ROM 31b to determine whether or not it is a big hit. A big hit judgment (hit lottery) is performed. In the present embodiment, the numerical values that can be taken by the jackpot determination random number are 0 to 946 (total of 947 different integers). Then, the main CPU 31a uses the three jackpot determination values determined in advance from the numbers that can be taken as the jackpot determination random numbers, and sets the jackpot lottery probability to 3/947 (= 315.7 / 1) to the jackpot. Make a decision.

  When the determination result of the big hit determination is negative (the value of the big hit determination random number and the big hit determination value do not match), the main CPU 31a shown in FIGS. 3 and 4 determines the loss. Then, the main CPU 31a determines that the special symbol B1 is a symbol “−” indicating a loss. Further, the main CPU 31a stores the data corresponding to the determined special symbol B1 in the main RAM 31c until the processing related to the next symbol variation game is performed. Further, the main CPU 31a compares the reach determination random number value read from the main RAM 31c with the reach determination value stored in the main ROM 31b, and determines whether to execute the lose reach. When the determination result of reach determination is affirmative (the value of the reach determination random number and the reach determination value match), the main CPU 31a determines the loss reach. Further, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and determines any one of the variation patterns P14, P15, P16, P17 for the lost reach effect based on the value.

  When the determination result of the reach determination is negative (the reach determination random number value and the reach determination value do not match), the main CPU 31a shown in FIGS. 3 and 4 determines a loss (a loss without a reach). . Then, the main CPU 31a reads the variation pattern distribution random number value from the main RAM 31c, and determines the variation pattern P13 for the loss effect based on the value.

  On the other hand, when the determination result of the jackpot determination is affirmative (the value of the jackpot determination random number and the jackpot determination value match), the main CPU 31a determines the jackpot. When the big hit is determined, the main CPU 31a determines the special symbol B1, which is a symbol related to the stop symbol (the effect symbol E1) derived in the symbol combination game, based on the symbol selection program. The symbol selection program is a program for causing the main CPU 31a to function as “symbol selection means”. That is, the main CPU 31a determines the special symbol B1 indicating any one of “0” to “9” based on the value of the jackpot symbol random number stored in the random number storage area of the main RAM 31c. More specifically, the main CPU 31a determines the symbol number specified based on the value of the jackpot symbol for random numbers from the symbol number table (see FIG. 5A), and refers to the determined symbol number for special. The design B1 is selected. The symbol number indicates the arrangement order of the special symbols B1 distributed in the symbol number table. For example, when the jackpot symbol random number is “0”, the main CPU 31a selects the symbol number “0” located on the leftmost in the symbol number table, and when the jackpot symbol random number is “7”, the main CPU 31a Selects the symbol number “7” located eighth from the left in the symbol number table. Then, the main CPU 31a stores a value (symbol number value) indicating the arrangement order of the selected special symbol B1 in the main RAM 31c as stop symbol data.

  The main CPU 31a shown in FIGS. 3 and 4 executes a plurality of game content determination processes for determining game contents based on the game content determination process execution program. The game content determination process execution program is a program for causing the main CPU 31a to function as “game content determination process execution means”. The game content determination process includes three processes: a special game state determination process, a special winning opening state selection process (specific game state selection process), and a variation pattern selection process. The special gaming state determination process includes two processes: a special symbol probability variation determination process and a normal symbol probability variation determination process.

  In the special symbol probability variation determination process, the main CPU 31a determines whether or not to give the special symbol probability variation after the end of the jackpot game effect. More specifically, the main CPU 31a selects special symbol probability variation flag data from the special symbol probability variation flag setting table (see FIG. 6) based on the special symbol type flag, and special symbol probability variation flag data is specially selected. The symbol probability variation flag is stored in the flag storage area of the main RAM 31c. For example, in the case of the special symbol type flag 00H, the main CPU 31a selects the special symbol probability variation flag 00H and determines that the special symbol probability variation is not given (non-probability variation). In the case of the special symbol type flags 01H and 02H, the main CPU 31a selects the special symbol probability variation flag 01H and determines that the special symbol probability variation is given. That is, the main CPU 31a has a function as “option selection means” for selecting one option from a plurality of preset options.

  If it is determined that the special symbol probability variation is to be given, the main CPU 31a starts giving the special symbol probability variation after the end of the jackpot game effect. Then, when the special symbol probability variation is started, the main CPU 31a uses 15 jackpot determination values from the possible values of the jackpot determination random number and determines the jackpot determination probability as 15/947. I do. That is, the number of jackpot determination values when the special symbol probability changes is five times that before the special symbol probability change. The special symbol probability variation may be continued until the next jackpot game effect is started, or the symbol variation display is executed a plurality of times (for example, 10,000 times). It may be continued for a while.

  Further, in the normal symbol probability variation determination process, the main CPU 31a shown in FIGS. 3 and 4 determines whether or not the normal symbol probability variation is given after the big hit game effect is finished. Specifically, the main CPU 31a selects the normal symbol probability variation flag data from the normal symbol probability variation flag setting table (see FIG. 7) based on the special symbol type flag, and uses the normal symbol probability variation flag data as the ordinary symbol probability variation flag data. The probability variation flag is stored in the flag storage area of the main RAM 31c. That is, since the same method as the case of the special symbol probability variation flag is used to select the normal symbol probability variation flag data to be the normal symbol probability variation flag, the main CPU 31a also functions as “option selection means” here. . In the present embodiment, regardless of any of the special symbol type flags 00H, 01H, and 02H, the main CPU 31a always selects the normal symbol probability variation flag 01H and determines that the normal symbol probability variation is always given.

  In the big prize opening state selection processing, the main CPU 31a shown in FIGS. 3 and 4 selects one big hit game effect from a plurality of big hit game effects when giving the big hit game effect. More specifically, the main CPU 31a selects table data for a special winning opening from a special winning table setting selection table (see FIG. 8) based on the special symbol type flag, and uses the special winning prize table data as a large winning prize. It is stored in the main RAM 31c as a mouth setting table. For example, in the case of the special symbol type flags 00H and 01H, the main CPU 31a selects the special winning opening setting table 0 (see FIG. 9). In the case of the special symbol type flag 02H, the main CPU 31a selects the special winning opening setting table 1 (see FIG. 10). Note that the same method as that for the special symbol probability variation flag and the normal symbol probability variation flag is used to select the table data for the special winning symbol as the grand prize opening setting table. Functions as "selection means". When the big prize opening setting table 0 is selected, the big prize opening number of times is “15” and the big prize opening time is “25 seconds”. When the special winning opening setting table 1 is selected, a big winning game effect is executed in which the number of special winning openings is “2” and the special winning opening is “0.5 seconds”.

  In the variation pattern selection process, the main CPU 31a shown in FIG. 3 and FIG. 4 selects variation pattern table data from the big hit variation pattern distribution selection table (see FIG. 11) based on the special symbol type flag, The variation pattern table data is stored in the main RAM 31c as a variation pattern distribution table address. In addition, since the same method as the case of the special symbol probability variation flag, the normal symbol probability variation flag, and the big prize opening setting table is used to select the variation pattern table data to be the variation pattern distribution table address, here However, the main CPU 31a functions as “option selection means”. For example, when the variation pattern distribution table address 1 is selected, the main CPU 31a assigns the big hit time variation pattern distribution table T1 (FIG. 12 (FIG. 12)) to which the variation pattern selected when the special symbol probability variation is not given. See a)). Then, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, any one of the variation patterns P1, P2, P3, P4 for the big hit effect from the big hit time variation pattern distribution table T1. Select one. When the variation pattern distribution table address 2 is selected, the main CPU 31a determines that the variation pattern selected when the normal special symbol probability variation is given is a big hit variation pattern distribution table T2 ( Reference is made to FIG. Then, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, any one of the variation patterns P5, P6, P7, and P8 for the big hit effect from the big hit time variation pattern distribution table T2. Select one. Further, when the variation pattern distribution table address 3 is selected, the main CPU 31a determines the big hit hour variation pattern distribution table T3 (FIG. 12C) to which the variation pattern selected when the sudden probability variation is given. Refer to)). Then, the main CPU 31a reads the value of the variation pattern distribution random number from the main RAM 31c, and based on the value, any one of the variation patterns P9, P10, P11, P12 for the big hit effect from the big hit time variation pattern distribution table T3. Select one.

  The special symbol type flag is set based on the symbol type setting program and the stop symbol data stored in the main RAM 31c. The symbol type setting program is a program for causing the main CPU 31a shown in FIGS. 3 and 4 to function as “symbol type setting means”. That is, when there are a plurality of special symbols B1 having the same combination of selected options, the main CPU 31a sets a special symbol type flag common to these special symbols B1. In other words, the main CPU 31a sets a different special symbol type flag for each symbol group when there are a plurality of symbol groups composed of a plurality of special symbols B1 having the same combination of selected options. More specifically, the main CPU 31a selects from the symbol type number table (see FIG. 5B) a special symbol type flag that is located at the same location as the arrangement order (the symbol number) serving as stop symbol data. ing. For example, when the symbol number is “0”, the main CPU 31a selects the symbol type flag 00H located at the leftmost in the symbol type number table, and when the symbol number is “7”, the main CPU 31a selects the symbol type The symbol type flag 02H located at the eighth position from the left in the number table is selected. That is, the symbol type flag is specified using the same technique as that for the symbol number. A specific example of specifying the symbol type flag is shown below.

  By the way, the design number of this embodiment is ten types of 0-9. The game content determination process includes four types: the special symbol probability fluctuation determination process, the normal symbol probability fluctuation determination process, the big prize opening state selection process, and the fluctuation pattern selection process. Further, two types of options selected in the special symbol probability variation determination process are the special symbol probability variation flags 00H and 01H, and one option selected in the normal symbol probability variation determination process is 1 of the normal symbol probability variation flag 01H. It is a kind. Also, the choices selected in the special winning opening state selection process are two types of the special winning prize setting tables 0 and 1, and the choices selected in the variation pattern selection process are the variation pattern allocation table addresses 1, 2, and 2. 3 types.

  When the symbol number is any one of “0”, “2”, “4”, “6”, “8”, the special symbol probability variation flag 00H is selected in the special symbol probability variation determination process, The normal symbol probability fluctuation flag 01H is selected in the normal symbol probability fluctuation determination process, the big prize opening setting table 0 is selected in the big prize opening state selection process, and the fluctuation pattern distribution table address 1 is selected in the fluctuation pattern selection process. . For this reason, the main CPU 31a shown in FIGS. 3 and 4 sets a special symbol type flag 00H common to symbol numbers 0, 2, 4, 6, and 8. In addition, when the symbol number is any one of “1”, “3”, “5”, “9”, the special symbol probability variation flag 01H is selected in the special symbol probability variation determination process, and the normal symbol probability variation The normal symbol probability variation flag 01H is selected in the determination processing, the large winning opening setting table 0 is selected in the large winning opening state selection processing, and the variation pattern distribution table address 2 is selected in the variation pattern selecting processing. Therefore, the main CPU 31a sets a special symbol type flag 01H common to symbol numbers 1, 3, 5, and 9. Further, when the symbol number is “7”, the special symbol probability variation flag 01H is selected in the special symbol probability variation determination processing, the normal symbol probability variation flag 01H is selected in the normal symbol probability variation determination processing, and the winning prize state The special winning opening setting table 1 is selected in the selection process, and the variation pattern allocation table address 3 is selected in the variation pattern selection process. Therefore, the main CPU 31a sets a common special symbol type flag 02H for the symbol number 7.

  Thereafter, the main CPU 31a shown in FIGS. 3 and 4 stores the set special symbol type flag in the flag storage area of the main RAM 31c. The main CPU 31a executes a plurality of the game content determination processes using the special symbol type flag stored in the main RAM 31c.

  The main CPU 31a having determined the special symbol B1 and the variation pattern sets the variation time associated with each variation pattern in the main RAM 31c as a variation timer (stored in the timer storage area of the main RAM 31c), and displays the special symbol display. The apparatus 51 is caused to start changing the special symbol B1. When the main CPU 31a instructs the overall control CPU 37a of the overall control board 37 to perform control, a control command or the like is used as a control signal (8-bit signal), and the signal is output via the output port 41 and the output buffer 42. Output at a predetermined timing. Specifically, the main CPU 31a first generates a variation pattern designation command for designating a variation pattern and instructing the start of symbol variation, and sets it as a control command (stored in the main RAM 31c). Next, the main CPU 31a sets a symbol number designation command for designating the special symbol B1 (symbol number) as a control command (stored in the main RAM 31c). The control commands set here are output in the order of the variation pattern designation command and the symbol number designation command in the subsequent output processing (not shown). Further, the main CPU 31a subtracts the variation timer set at the beginning of the variation every interrupt (4 ms). When the variation time associated with the variation pattern has elapsed (when the variation timer reaches 0 ms), the main CPU 31a causes the special symbol display device 51 to display the special symbol B1 determined at the start of variation. Further, the main CPU 31a sets (outputs) an effect symbol stop designation command that instructs to stop symbols in each column as a control command in accordance with the passage of the variation time.

  In the big hit gaming state, there are an opening period, a round period (a period in which the big winning opening 24 is open), and an ending period. In the opening period, an opening effect is performed to announce the start of the jackpot gaming state. In the round period, an interval effect is performed between rounds during the jackpot game. In the ending period, the end of the jackpot gaming state is notified. Ending production is executed. Therefore, the main CPU 31a shown in FIGS. 3 and 4 generates an opening designation command for instructing the start of the opening period after the production symbol stop designation command is outputted, and outputs it as a control command. Next, the main CPU 31a outputs a round designation command for instructing the start of the round period as a control command. Specifically, the main CPU 31a instructs the start of the first to fifteenth round periods when the special prize opening setting table 0 (see FIG. 9) is selected in the special prize opening state selection process. The 1st to 15th round designation commands are sequentially output as control commands. The main CPU 31a also instructs the first and second rounds to start the first and second round periods when the special prize opening setting table 1 (see FIG. 10) is selected in the special prize opening state selection process. The specified command is output in order as a control command. Thereafter, the main CPU 31a outputs an ending designation command for instructing the start of the ending period as a control command.

Further, the main CPU 31a outputs a read signal (INT signal or strobe signal) for instructing the overall control board 37 to read a control command constituting the control signal in accordance with the output timing of the control signal. And output via the output buffer 42.
(3-2) Electrical configuration of overall control board 37

  As shown in FIG. 4, the overall control board 37 includes an overall control CPU 37a. The general control CPU 37a is electrically connected to an input buffer 43 for inputting control signals and read signals output from the main CPU 31a. Further, an input port 44 is electrically connected to the input buffer 43, and a control signal is input to the overall control CPU 37a via the input port 44.

  In addition, an overall ROM 37b and an overall RAM 37c are connected to the overall control CPU 37a. The overall control CPU 37a updates the values of various random numbers used for determining the game effect at predetermined intervals. The overall control CPU 37a sets the updated value in the setting area of the overall RAM 37c and rewrites the value before the update. For example, the random number storage area of the overall RAM 37c stores a random number for lost left symbol, a random number for lost symbol, a random number for lost right symbol, and the like.

  When a variation pattern designation command is input, the overall control CPU 37a shown in FIGS. 3 and 4 stores the variation pattern designated by the variation pattern designation command in the overall RAM 37c. If it is determined that a symbol number designation command has been input, the overall control CPU 37a stores the special symbol B1 designated by the symbol number designation command in the overall RAM 37c.

  Furthermore, the overall control CPU 37a determines the effect design E1 based on the special design B1 stored in the overall RAM 37c. For example, when the special symbol B1 stored in the overall RAM 37c is any one of “0” to “9”, the variation pattern stored in the overall RAM 37c is any of the variation patterns P1 to P12 for the big hit effect. Or one. In this case, the overall control CPU 37a determines the effect symbol E1 (effect symbol left, middle, right) to be finally stopped by the symbol display device 18 so that all the columns are the same type of symbol. Specifically, the overall control CPU 37a determines the effect symbol left, the effect symbol in the effect symbol, and the effect symbol right (each effect symbol is the same type) based on the special symbol B1. For example, if the special symbol B1 is “0”, the effect symbol E1 is “0”, and if the special symbol B1 is “1”, the effect symbol E1 is “1”. The determined effect symbol left, the effect symbol, and the effect symbol right are derived to the symbol display device 18 as a final symbol combination. Then, the overall control CPU 37a stores data corresponding to the determined effect symbol left, effect symbol, and effect symbol right in the overall RAM 37c.

  The special symbol B1 stored in the overall RAM 37c shown in FIGS. 3 and 4 is “−”, and the variation pattern stored in the overall RAM 37c is any one of the variation patterns P14 to P17 for losing reach production. If it is, the overall control CPU 37a determines the loss reach. In this case, the overall control CPU 37a determines the effect symbols left, middle, and right so that the left column and the right column are the same type of symbols, and the middle column is a different type of symbols from the left and right columns. Specifically, the effect symbol left and the effect symbol right (both effect symbols are of the same type) are determined based on the value of the random number for the left symbol. Then, based on the value of the random symbol for losing symbol, the effect symbol is determined. If the value of the random symbol for losing pattern and the random number value for the losing left symbol (or the value of the random number for the losing right symbol) match, the overall control CPU 37 a The production pattern is determined so that (right) does not match. In the present embodiment, the numbers that can be taken by random numbers for the left symbol for lost, the random number for right for lost, and the random number for middle for lost are 10 integers from 0 to 9, and one numerical value corresponds to each type of symbol. It is attached.

  When the special symbol B1 stored in the overall RAM 37c shown in FIGS. 3 and 4 is “−” and the variation pattern stored in the overall RAM 37c is the variation pattern P13 for losing effect, the overall control CPU 37a. Decides to lose. In this case, the overall control CPU 37a determines the effect symbols left, middle, and right so that all the columns do not become the same type of symbols. Specifically, the effect symbol left is determined based on the value of the lost symbol for the left symbol, the effect symbol is determined based on the value of the random symbol for the middle symbol, and the effect is determined based on the value of the random number for the right symbol Determine the symbol right. When the value of the random number for the lost symbol and the value of the random number for the right symbol for the match match, the overall control CPU 37a determines the effect symbol right so that the effect symbol left and the effect symbol right do not match.

  Then, the overall control CPU 37a uses, as control commands, a change pattern designation command for designating a change pattern stored in the overall RAM 37c, as a control command, and the voice / lamp control board 34. This is output to the lamp control CPU 34a. As a result, the specific contents of the game effects executed by the display control board 33 and the sound / lamp control board 34 are comprehensively controlled by the overall control board 37.

  Further, the overall control CPU 37a shown in FIGS. 3 and 4 outputs an effect symbol left designation command for designating the effect symbol left of the effect symbol E1 to the display control CPU 33a as a control command. Similarly, the overall control CPU 37a sends, to the display control CPU 33a, an effect symbol right designation command that designates the effect symbol right of the effect symbol E1 and an effect symbol middle designation command that designates the effect symbol within the effect symbol E1 as control commands. Output.

  Thereafter, when the effect symbol stop designation command is input from the main CPU 31a shown in FIGS. 3 and 4, the overall control CPU 37a uses the input effect symbol stop designation command as a control command, the display control CPU 33a and the voice / lamp. Output to the control CPU 34a.

  When the opening designation command is input from the main CPU 31a, the overall control CPU 37a outputs the input opening designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a. Next, when the first to fifteenth round designation commands or the first and second round designation commands are inputted from the main CPU 31a, the overall control CPU 37a sequentially uses the inputted round designation commands as control commands. Output to the display control CPU 33a. Thereafter, when the ending designation command is input from the main CPU 31a, the overall control CPU 37a outputs the input ending designation command as a control command to the display control CPU 33a and the sound / lamp control CPU 34a.

The overall control CPU 37a shown in FIGS. 3 and 4 uses the above control commands and the like as control signals (8-bit signals), and outputs the signals via the output port 45 and the output buffer 46 at a predetermined timing. Further, the overall control CPU 37a, in accordance with the output timing of the control signal, instructs the display control board 33 and the voice / lamp control board 34 to read a control command constituting the control signal (INT signal or , The strobe signal) is output via the output port 45 and the output buffer 46.
(3-3) Electrical configuration of display control board 33

  As shown in FIG. 3, the display control board 33 includes the display control CPU 33a, and a display ROM (not shown) and a display RAM (not shown) are connected to the display control CPU 33a. The display RAM temporarily stores (sets) various information that can be appropriately rewritten during the operation of the pachinko machine 10.

  The display ROM stores a plurality of types of display effect data used when the symbol combination game is performed. The display effect data is information for the display control CPU 33a to control the display content (symbol fluctuation or the like) of the symbol display device 18, that is, information for instructing the symbol display device 18 to execute the display effect. .

  Further, the display ROM includes one type of opening period display effect data, 15 types of round period display effect data, and one type of ending period display effect data used in the jackpot gaming state after the symbol combination game. It is remembered. Opening period display effect data is stored in association with the opening period. Each round period display effect data is stored in association with each of the first to fifteenth round periods. Each ending period display effect data is stored in association with the ending period. The display effect data for the opening period, the display effect data for the round period, and the display effect data for the ending period are displayed on the symbol display device 18 by the display control CPU 33a for the effects of the opening period, the first to fifteenth round periods, and the ending period. This is information for instructing execution.

  When the change pattern designation command is input from the overall control CPU 37a shown in FIGS. 3 and 4, the display control CPU 33a stores the change pattern designated by the change pattern designation command in the display RAM. It has become.

  Further, when the effect symbol left designation command is input from the overall control CPU 37a, the display control CPU 33a stores the effect symbol left designated by the command in the display RAM. Similarly, when the presentation design right designation command is input from the overall control CPU 37a, the display control CPU 33a stores the production design right designated by the command in the display RAM, and when the production design middle designation command is inputted. The effect symbols designated by the command are stored in the display RAM.

  Thereafter, when the effect symbol stop designation command is input from the overall control CPU 37a shown in FIGS. 3 and 4, the display control CPU 33a displays the effect symbols left, right, and center stored in the display RAM input at the start of the variation. Based on the above, the symbol display device 18 is instructed to stop the effect symbol E1. As a result, the designated effect symbol E1 is stopped and displayed on the symbol display device 18.

  When the variation pattern designation command is input, the display control CPU 33a sets (generates) any one of the plurality of types of display effect data stored in the display ROM, and sets the display effect. Data is stored in a storage area of the display RAM. Thereby, the display control CPU 33a performs display control based on the variation pattern designation command and the display effect data. More specifically, the display control CPU 33a converts display effect data stored in the display RAM into a symbol signal and outputs the symbol signal to the symbol display device 18. As a result, the symbol display device 18 can perform a predetermined display based on the symbol signal.

  Further, when the opening designation command is input, the display control CPU 33a sets (generates) the opening period display effect data stored in the display ROM, and stores the set opening period display effect data in the display RAM. It is designed to be stored in the area. As a result, the display control CPU 33a performs display control based on the opening designation command and the display effect data for the opening period. When the first to fifteenth round designation commands (or the first and second round designation commands) are input, the display control CPU 33a selects any of the 15 types of round period display effect data stored in the display ROM. One is set (generated), and the set display effect data for the round period is stored in the storage area of the display RAM. Thus, the display control CPU 33a performs display control based on each round designation command and round period display effect data.

When the ending designation command is input, the display control CPU 33a shown in FIG. 3 sets (generates) the ending period display effect data stored in the display ROM, and displays the set ending period display effect data. The data is stored in a RAM storage area. As a result, the display control CPU 33a performs display control based on the ending designation command and the ending period display effect data. More specifically, the display control CPU 33a converts the display effect data for the opening period, the display effect data for the round period, and the display effect data for the ending period stored in the display RAM into a symbol signal and outputs it to the symbol display device 18. . As a result, the symbol display device 18 can perform a predetermined display based on the symbol signal.

The light effect data is information for the sound / lamp control CPU 34a to control the light output mode of the top lamp 16. The voice effect data is information for the voice / lamp control CPU 34a to control the voice output mode (sound effect type, language voice type, voice output time, etc.) of the speaker 17.

  Further, the voice / lamp ROM stores one type of opening period effect data and one type of ending period effect data used in the big hit gaming state after the symbol combination game. The opening period effect data is stored in association with the opening period. Ending period effect data is stored in association with each ending period. The opening period effect data and the ending period effect data are information for the voice / lamp control CPU 34a to instruct the top lamp 16 and the speaker 17 to execute effects during the opening period and the ending period.

  When the change pattern designation command is input from the overall control CPU 37a shown in FIGS. 3 and 4, the voice / lamp control CPU 34a displays the change pattern designated by the change pattern designation command in the voice / lamp RAM. To come to remember.

  Thereafter, when the production symbol stop designation command is input from the overall control CPU 37a, the voice / lamp control CPU 34a instructs the top lamp 16 to stop the light emission and also instructs the speaker 17 to stop the voice output. ing.

The set light emission effect data is stored in the storage area of the voice / lamp RAM. Thereby, the voice / lamp control CPU 34a performs the light emission control based on the light emission effect data corresponding to the variation pattern designation command. More specifically, the sound / lamp control CPU 34a converts the light emission effect data stored in the sound / lamp RAM into a light emission control signal and outputs it to the top lamp 16. As a result, the top lamp 16 can perform a predetermined light emission operation (lighting, blinking, etc.) based on the light emission control signal.

  When a change pattern designation command is input, the voice / lamp control CPU 34a shown in FIG. 3 sets (generates) one of the plurality of types of voice effect data stored in the voice / lamp ROM. Thus, the set audio production data is stored in the storage area of the audio / lamp RAM. Thereby, the voice / lamp control CPU 34a performs voice control based on the voice effect data corresponding to the variation pattern designation command. More specifically, the sound / lamp control CPU 34 a converts sound effect data stored in the sound / lamp RAM into a sound signal and outputs the sound signal to the speaker 17. As a result, the speaker 17 can perform a predetermined output operation (sound output) based on the audio signal.

  Further, when the opening designation command is input, the voice / lamp control CPU 34a sets (generates) the opening period effect data stored in the voice / lamp ROM, and the set opening period effect data is set to the voice / lamp control data. The data is stored in the storage area of the lamp RAM. As a result, the sound / lamp control CPU 34a performs light emission control and sound control based on the opening designation command and the opening period effect data. When the ending designation command is input, the sound / lamp control CPU 34a sets (generates) ending period effect data stored in the sound / lamp ROM, and the set ending period effect data is set to the sound / lamp RAM. Are stored in the storage area. Accordingly, the sound / lamp control CPU 34a performs light emission control and sound control based on the ending designation command and the ending period effect data. More specifically, the sound / lamp control CPU 34a converts the opening period effect data and the ending period effect data stored in the sound / lamp RAM into light emission control signals and sound signals, and outputs them to the top lamp 16 and the speaker 17. To do. As a result, the top lamp 16 and the speaker 17 can perform predetermined light emission and audio output based on the light emission control signal and the audio signal.

  Next, processing (timer interrupt processing) performed by the main CPU 31a of the main control board 31 will be described. Note that a program for performing this process is executed in the main CPU 31a every predetermined interrupt period (every 4 ms).

  In FIG. 14, the main CPU 31a proceeds to the process (input process) of step S100 and executes the subroutine shown in FIG.

  The subroutine of FIG. 15 includes the processes of steps S200 to S204. In step S <b> 200, the main CPU 31 a determines whether or not a game ball has won the start winning opening 22. When the game ball wins (step S200: Y), the main CPU 31a proceeds to the process of step S201. On the other hand, when the game ball has not won (step S200: N), the main CPU 31a ends this subroutine without performing the processing of steps S201 to S204.

  In step S201, the main CPU 31a determines whether or not the number of special symbol reservation balls of the game ball that is added in step S202 described later and subtracted in step S301 described later is less than “4” at the present time. . When the number of special symbol reservation balls is less than 4 (step S201: Y), the main CPU 31a proceeds to the process of step S202. On the other hand, when the number of special symbol reservation balls is 4 or more (step S201: N), the main CPU 31a executes this subroutine without performing the processing of steps S202 to S204 without adding the number of special symbol reservation balls. finish. That is, in the pachinko machine 10 of this embodiment, the upper limit of the number of special symbol reservation balls is set to four.

  In step S202, the winning of the game ball is determined in step S200, and it is determined in step S201 that the number of special symbol reservation balls is less than 4. Therefore, the main CPU 31a sets the number of special symbol reservation balls to one. After the addition, the process proceeds to step S203. In step S203, the main CPU 31a obtains a jackpot determination random number that is updated as needed in a random number update process described later, and proceeds to the process of step S204. Note that the big hit determination random number acquired here is used when performing the process of step S302 described later. In step S204, the main CPU 31a stores the big hit determination random number acquired in step S203 in the random number storage area of the main RAM 31c. Then, the main CPU 31a ends this subroutine.

  When the subroutine shown in FIG. 15 is completed, the main CPU 31a proceeds to the process of step S101 (random number update process) shown in FIG. 14, and executes the subroutine shown in FIG.

  The subroutine of FIG. 16 includes the processes of steps S800 to S808. In step S800, the main CPU 31a determines whether or not the big hit determination random number added by 1 in step S801 described later is 946. When the big hit determination random number is not 946 (step S800: N), the main CPU 31a proceeds to the process of step S801. On the other hand, when the big hit determination random number is 946 (step S800: Y), the main CPU 31a proceeds to the process of step S802.

  In step S801, the main CPU 31a adds 1 to the jackpot determination random number, and proceeds to the process of step S803. In step S802, since the main CPU 31a determines that the big hit determination random number is 946 in step S800, the main CPU 31a clears the big hit determination random number (sets it to 0), and proceeds to the processing of step S803. . That is, in steps S800 to S802, the main CPU 31a performs a process of adding one to the big hit determination random number and returning it to 0 when it is added up to 946. Therefore, the big hit determination random number is updated one by one within the range of 0 to 946.

  In step S803, the main CPU 31a determines whether or not the reach determination random number added by 1 in step S804 described later is 240. If the reach determination random number is not 240 (step S803: N), the main CPU 31a proceeds to the process of step S804. On the other hand, if the reach determination random number is 240 (step S803: Y), the main CPU 31a proceeds to the process of step S805.

  In step S804, the main CPU 31a adds 1 to the reach determination random number, and proceeds to the process of step S806. In step S805, since the reach determination random number is determined to be 240 in step S803, the main CPU 31a clears the reach determination random number (sets it to 0), and proceeds to step S806. . That is, in steps S803 to S805, the main CPU 31a performs a process of adding one to the reach determination random number and returning to 0 when 240 is added. Therefore, the reach determination random number is updated one by one within the range of 0 to 240.

  In step S806, the main CPU 31a determines whether or not the variation pattern distribution random number added by 1 in step S807 described later is 99. If the fluctuation pattern distribution random number is not 99 (step S806: N), the main CPU 31a proceeds to the process of step S807. On the other hand, when the variation pattern distribution random number is 99 (step S806: Y), the main CPU 31a proceeds to the process of step S808.

  In step S807, the main CPU 31a adds 1 to the variation pattern distribution random number and ends this subroutine. In step S808, the main CPU 31a determines that the variation pattern distribution random number is 99 in step S806. Therefore, the main CPU 31a clears the variation pattern distribution random number (sets it to 0) and ends this subroutine. . That is, in steps S806 to S808, the main CPU 31a performs a process of adding the variation pattern distribution random numbers one by one and returning to 0 when 99 is added. Therefore, the fluctuation pattern distribution random numbers are updated one by one within the range of 0 to 99.

  When the subroutine shown in FIG. 16 ends, the main CPU 31a proceeds to the process of step S102 shown in FIG. In step S102, the main CPU 31a determines whether or not a symbol combination game is being performed on the symbol display device 18. When the symbol combination game is being performed (step S102: Y), the main CPU 31a proceeds to the process of step S104 without performing the process of step S103. On the other hand, when the symbol combination game is not performed (step S102: N), the main CPU 31a proceeds to the process of symbol S103 (symbol changing game start processing) and executes the subroutine shown in FIG.

  The subroutine of FIG. 17 includes the processes of steps S300 to S304. In step S300, the main CPU 31a determines whether or not the number of special symbol reservation balls is “0” at the present time. When the number of special symbol reservation balls is other than 0 (1 to 4) (step S300: N), the main CPU 31a proceeds to the process of step S301 in order to start the symbol variation game. On the other hand, when the number of special symbol reservation balls is 0 (step S300: Y), the main CPU 31a executes this subroutine without performing the processing of steps S301 to S304 without further subtracting the number of special symbol reservation balls. finish.

  In step S301, the main CPU 31a subtracts 1 from the number of special symbol reservation balls, and proceeds to the process of step S302. In step S302, the main CPU 31a performs a jackpot determination by comparing the jackpot determination random number stored in the random number storage area of the main RAM 31c in step S204 with the jackpot determination value. Here, there are three jackpot determination values “7”, “321”, and “635”. If the comparison result does not match (step S302: N), the main CPU 31a shifts to the processing of step S304 (losing variation processing) to execute the subroutine shown in FIG. .

  The subroutine in FIG. 18 includes the processes of steps S401 to S403. In step S401, the main CPU 31a acquires the reach determination random number that is updated as needed in the random number update process, proceeds to the process of step S402 (variation pattern determination process), and executes the subroutine shown in FIG. .

  The subroutine of FIG. 19 includes the processes of steps S700 to S702. In step S700, the main CPU 31a obtains the variation pattern distribution random numbers updated as needed in the random number update process, and proceeds to the process in step S701. In step S701, the main CPU 31a determines any one of the variation patterns P13 to P17 based on the loss variation pattern distribution table (see FIG. 13) and the variation pattern distribution random number acquired in step S700. .

  Then, the main CPU 31a proceeds to the process of step S702. In step S702, the main CPU 31a outputs the variation pattern determined in step S701 as a variation pattern designation command to the overall control CPU 37a of the overall control board 37, and ends this subroutine.

  When the subroutine shown in FIG. 19 ends, the main CPU 31a proceeds to the process (design determination process) in step S403 shown in FIG. In step S403, the main CPU 31a determines the special symbol B1 in the symbol variation game to be performed this time to be a symbol “−” indicating a loss, and ends the present subroutine.

  Further, when the subroutine shown in FIG. 18 ends, the main CPU 31a ends the subroutine shown in FIG.

  On the other hand, if the comparison result is the same (step S302: Y), the main CPU 31a shifts to the processing of step S303 (big hit variation processing) in order to win the symbol variation game to be performed from now on, as shown in FIG. Run a subroutine.

  The subroutine in FIG. 20 includes the processes of steps S500 to S514. In step S500, the main CPU 31a confirms the jackpot symbol random number stored in the random number storage area of the main RAM 31c, and proceeds to the process of step S501. In step S501, the main CPU 31a selects a symbol number specified based on the value of the jackpot symbol random number confirmed in step S500 from the symbol number table (see FIG. 5A), and proceeds to the processing of step S502. To do. In step S502, the main CPU 31a stores the value of the selected symbol number as stop symbol data in the main RAM 31c, and proceeds to the processing of step S503.

  In step S503, the main CPU 31a selects a special symbol type flag corresponding to the stopped symbol data (symbol number) stored in the main RAM 31c from the symbol type number table (see FIG. 5B), and performs the process of step S504. Migrate to In step S504, the main CPU 31a stores the special symbol type flag in the flag storage area of the main RAM 31c, and proceeds to the processing in step S505 (special symbol probability variation determination processing).

  In step S505, the main CPU 31a obtains the special symbol probability variation flag data from the special symbol probability variation flag setting table (see FIG. 6) based on the special symbol type flag stored in the flag storage area of the main RAM 31c in step S504. select. Thereby, it is determined whether or not the special symbol probability variation is given after the end of the big hit game effect. In the subsequent step S506, the main CPU 31a stores the selected special symbol probability variation flag data as a special symbol probability variation flag in the flag storage area of the main RAM 31c, and proceeds to the processing of step S507 (normal symbol probability variation determination processing). .

  In step S507, the main CPU 31a selects the normal symbol probability variation flag data from the normal symbol probability variation flag setting table (see FIG. 7) based on the special symbol type flag stored in the flag storage area of the main RAM 31c. Thereby, it is determined whether or not the normal symbol probability variation is given after the end of the big hit game effect. In the following step S508, the main CPU 31a stores the selected normal symbol probability variation flag data as a normal symbol probability variation flag in the flag storage area of the main RAM 31c, and proceeds to the processing of step S509 (large winning opening state selection processing). .

  In step S509, the main CPU 31a selects table data for the special winning a prize mouth from the special winning mouth setting selection table (see FIG. 8) based on the special symbol type flag stored in the flag storage area of the main RAM 31c. As a result, the movement of the big winning opening 24 in the big hit game production (the number of times of opening the big winning opening and the opening time of the big winning opening) is determined. In the subsequent step S510, the main CPU 31a stores the big prize mouth table data in the main RAM 31c as the big prize mouth setting tables 0 and 1 (see FIGS. 9 and 10). Here, the big winning opening setting tables 0 and 1 stored in the main RAM 31c are used in the process (big hit process) of step S104 shown in FIG. Then, the main CPU 31a proceeds to the process of step S511 (variation pattern selection process).

  In step S511, the main CPU 31a selects variation pattern table data from the variation table distribution selection table for big hit (see FIG. 11) based on the special symbol type flag stored in the flag storage area of the main RAM 31c. The process proceeds to step S512. In step S512, the main CPU 31a stores the variation pattern table data in the main RAM 31c as a variation pattern distribution table address, and proceeds to the processing in step S513.

  In step S513, the main CPU 31a, based on the variation pattern distribution random number stored in the random number storage area of the main RAM 31c, corresponds to the big hit hour variation pattern distribution table corresponding to the variation pattern distribution table address stored in the main RAM 31c. A variation pattern is selected from (see FIGS. 12A to 12C). In subsequent step S514, the main CPU 31a stores the variation pattern as a variation pattern number in the main RAM 31c, and ends the present subroutine. The variation pattern designation command for designating the selected variation pattern is output in the next and subsequent output processing (not shown).

  When the subroutine shown in FIG. 20 is finished, the main CPU 31a finishes the subroutine shown in FIG. 17, and proceeds to the processing in step S104 shown in FIG. In step S104, the main CPU 31a performs the jackpot determination similar to step S302 shown in FIG. When the determination result of the big hit determination is not a big hit, the main CPU 31a proceeds to the process of step S105. On the other hand, when the determination result of the big hit determination is a big hit, the main CPU 31a checks the big winning opening setting table stored in the main RAM 31c in the step S510 shown in FIG. Then, the main CPU 31a performs the following processing based on the special winning opening setting table stored in the main RAM 31c. That is, the main CPU 31a generates an opening designation command for instructing the start of the opening period, and outputs it to the overall control CPU 37a of the overall control board 37 as a control command. Next, the main CPU 31a outputs a round designation command instructing the start of the round period to the overall control CPU 37a as a control command. Specifically, when the special winning opening setting table 0 (see FIG. 9) is stored in the main RAM 31c, the main CPU 31a instructs the first to fifteenth rounds to start the first to fifteenth round periods. The designated commands are sequentially output to the overall control CPU 37a as control commands. Further, when the big prize opening setting table 1 (see FIG. 10) is stored in the main RAM 31c, the main CPU 31a sends the first and second round designation commands for instructing the start of the first and second round periods. The control commands are sequentially output to the overall control CPU 37a. Thereafter, the main CPU 31a outputs an ending designation command for instructing the start of the ending period to the overall control CPU 37a as a control command. Then, the main CPU 31a proceeds to the process of step S105.

  In step S105, the main CPU 31a stands by until 4 ms elapses after the process of step S100 is started. After 4 ms elapses, the main CPU 31a proceeds to the process of step S100 again.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) In the pachinko machine 10 of the present embodiment, the special symbol type flag 00H common to the special symbols B1 of “0”, “2”, “4”, “6”, “8” is set, and “1” , “3”, “5”, “9”, the common special symbol type flag 01H is set for the special symbol B1, and the special symbol type flag 02H is set for the special symbol B1 of “7”. As a result, the main CPU 31a can execute the game content determination process using the special symbol type flags having three types (three types) less than the special symbol B1 types (10 types). Accordingly, as compared with the case where the special symbol B1 is used, the special symbol probability variation flag setting table (see FIG. 6), the normal symbol probability variation flag setting table (see FIG. 7), and the winning prize setting selection table (FIG. 8). And the number of data in the big hit hour variation pattern distribution selection table (see FIG. 11) decreases. More specifically, the number of data in each table decreases from twice the number of special symbol B1 (10 × 2 = 20) to twice the number of symbol type (3 × 2 = 6). As a result, since the data area stored in the main ROM 31b can be compressed, the burden on the main CPU 31a when performing processing using each table can be reduced. Further, it becomes easy to secure the data area of the main ROM 31b, and it becomes easy to add a new program to the main ROM 31b, so that the development burden can be reduced. In addition, there are 10 types of special symbols B1 in the present embodiment, but the more special symbols B1 are, the more effect is obtained by executing the game content determination process using the special symbol type flag instead of the special symbols B1. Become prominent.

  (2) In step S501 of the present embodiment, the main CPU 31a selects the special symbol B1 by referring to the symbol number designated by the value of the jackpot symbol random number from the symbol number table (see FIG. 5A). It is carried out. In step S503, the main CPU 31a sets the special symbol type flag by referring to the symbol number arrangement order from the symbol type number table (see FIG. 5B). That is, in steps S502 and S503, the main CPU 31a specifies one value (special symbol B1 and special symbol type flag) by the same method, so that a program for operating the main CPU 31a can be shared to some extent.

  The same applies to the processing in steps S505, S507, S509, and S511. In the process of step S505 (special symbol probability variation determination processing), the main CPU 31a refers to the special symbol probability variation flag data selected from the special symbol probability variation flag setting table (see FIG. 6) based on the special symbol type flag. Thus, the special symbol probability variation flag is selected. Further, in the process of step S507 (ordinary symbol probability fluctuation determination process), the main CPU 31a receives the normal symbol probability fluctuation flag data selected from the normal symbol probability fluctuation flag setting table (see FIG. 7) based on the special symbol type flag. By referring to, the normal symbol probability variation flag is selected. Further, in the process of step S509 (large winning opening state selection processing), the main CPU 31a uses the special winning symbol setting flag based on the special winning symbol setting selection table (see FIG. 8) based on the special symbol type flag. By referring to, the winning prize opening setting table is selected. Further, in the process of step S511 (variation pattern selection process), the main CPU 31a refers to the variation pattern table data selected from the variation table distribution selection table (see FIG. 11) for the big hit based on the special symbol type flag. By doing so, the variation pattern distribution table address is selected. That is, in steps S505, S507, S509, and S511, the main CPU 31a specifies one value (special symbol probability variation flag, normal symbol probability variation flag, big prize opening setting table, variation pattern allocation table address) by the same method. Therefore, also in this case, a program for operating the main CPU 31a can be shared to some extent.

  (3) By the way, it is conceivable to execute a plurality of game content determination processes using the special symbol B1 without using the special symbol type flag. In this case, if the number or type of the special symbol B1 is changed, the symbol number table (see FIG. 5A), the symbol type number table (see FIG. 5B), the special symbol probability variation flag setting table (see FIG. 6). ), The contents of the normal symbol probability variation flag setting table (see FIG. 7), the big winning opening setting selection table (see FIG. 8) and the big hit variation pattern distribution selection table (see FIG. 9) need to be changed. There is. On the other hand, when changing the number or type of the special symbol B1 in the present embodiment, it is only necessary to change the symbol number table and the symbol type number table among the above-mentioned tables, so that the design change is easy.

  (4) In this embodiment, the production symbol E1 is created not by the main CPU 31a but by the overall control CPU 37a, so that the burden on the main CPU 31a can be further reduced.

  In addition, you may change embodiment of this invention as follows.

  The game content determination process of the above embodiment has three types of special game state determination process, specific game state selection process, and variation pattern selection process, but the game content determination process may be two or less types, There may be four or more types. The special gaming state determination process of the above embodiment is a special symbol probability fluctuation determination process and a normal symbol probability fluctuation determination process, but a process for determining a special symbol fluctuation time reduction (special symbol fluctuation time reduction determination process). There may also be a process for determining shortening of the variation time of the normal symbol (ordinary symbol variation time shortening determination process). Furthermore, although the specific game state selection process of the above-described embodiment was a big prize opening state selection process, a process of selecting an opening effect time (opening effect time selection process) and a process of selecting an interval effect time (interval effect) There may be a time selection process), a process of selecting an ending effect time (ending effect time selection process), and the like.

  In the above embodiment, the normal symbol probability variation flag that can be selected from the normal symbol probability variation flag setting table (see FIG. 7) by the main CPU 31a is only one type of the ordinary symbol probability variation flag 01H. However, there may be a plurality of types of normal symbol probability variation flags that can be selected from the normal symbol probability variation flag setting table. For example, in addition to the normal symbol probability variation flag 01H of the above embodiment, there may be a normal symbol probability variation flag 00H indicating that the normal symbol probability variation is not given (non-probability variation).

  -In the big hit fluctuation process (refer FIG. 20) of the said embodiment, you may change the order of step S505, S506, step S507, S508, step S509, S510 and step S511-S514. For example, the processes of steps S507 and S508 may be performed first, and then the processes of steps S505 and S506 may be performed.

  In the above embodiment, the production symbol E1 is determined by the overall control CPU 37a, but may be determined by the main CPU 31a. In the above embodiment, since the burden on the main CPU 31a is reduced by using the special symbol type flag for execution of the game content determination process, it is easy to determine the effect symbol E1 by the main CPU 31a.
