Abstract

PROBLEM TO BE SOLVED: To solve the problem that programming operation when distributing a different number of rounds for each pattern and changing the distribution rate is complex in a game machine including a plurality of patterns.SOLUTION: A common data table where determination data are individually allocated to the same comparison value is used for a first special pattern and a second special pattern. Thus, when the comparison value is changed on the table, a probability variable ratio can be changed simultaneously to both of the first special pattern and the second special pattern. When a jackpot pattern random number value is identical, a 15 round probability variable pattern (001H) is allowed to result in the second special pattern while a second round probability variable pattern (003H) is allowed to result in the first special pattern.

Description

  The present invention relates to a gaming machine that variably displays a plurality of symbols for each event that has become a lottery trigger when a lottery is performed during a game, and in particular, an aspect of a winning symbol (or winning type, This is related to the process of determining the type of winning) by design.

  Conventionally, there are two start ports, a first start port and a second start port arranged in the game area, and when winning to each start port is detected, the first big hit lottery or the second big hit lottery is performed separately. A gaming machine is known (for example, refer to Patent Document 1). This known gaming machine derives and displays the first display mode or the second display mode (corresponding to the stop symbol of the first special symbol or the second special symbol) corresponding to each of the two jackpot lotteries. In order to derive and display each display mode separately, a first special symbol display and a second special symbol display are provided.

  Also, known game machines extract the first big hit symbol random number or the second big hit symbol random number when determining the display mode of the first special symbol or the second special symbol. These two jackpot symbol random numbers are used separately for the first jackpot lottery and the second jackpot lottery (that is, the first special symbol and the second special symbol). For this reason, a known gaming machine has a jackpot symbol table for each symbol, and among these, the first jackpot lottery table has a probability variation determination value (0 to 0) for the first jackpot symbol random number (0 to 9). 6) is set, and the probability variation determination value (0 to 69) for the second big hit symbol random number (0 to 99) is set in the other second big hit lottery table (FIG. 1). (See 16 (b).)

  In this case, the first jackpot symbol random number and the second jackpot symbol random number are different from each other in the range of all random values (0 to 9, 0 to 99). Since 7/10 and 70/100 are set, respectively, as a result, in the first big hit lottery and the second big hit lottery, the probability variation rush rates coincide with each other at 70%.

JP 2007-29242 A (pages 34-37, FIG. 16, FIG. 20, FIG. 21)

  However, in the case of a known game machine, if the basic game specifications (hit probability, probability change rush rate, etc.) are changed and the invention is implemented (for example, commercialized by specifications), it is necessary to correct two tables for each design. Therefore, the work of matching the tables becomes complicated. For example, when it is desired to change the probability variation entry rate of the entire gaming machine, it is necessary to change the probability variation determination values for two tables, and then check the consistency between the two tables. In the above example, if the probability change entry rate after change is 50%, for example, for one table, the probability change determination value of the first big hit symbol random number is changed from “0-6” before change to “0-4” In the other table, the probability variation determination value of the second big hit symbol random number is corrected from “0-69” before change to “0-49”, and the ratio of the probability variation determination values of both matches. It is necessary to check whether or not. At this time, if there is a mistake in the confirmation or a mistake in the correction, the ratio between the two does not match, resulting in inconsistency that the probability variation rush rate is different between the two symbols.

  Furthermore, in recent years, the demand for diversification of gaming specifications has increased, so in gaming machines having a plurality of symbols (the total number of jackpot determined random numbers stored is 8), while matching the probability variation rush rate between symbols, There are an increasing number of cases in which game specifications are adopted in which the number of rounds during a big hit is different for each symbol. Specifically, the number of rounds in a big hit is always the maximum (for example, 15 rounds) for one symbol, but the number of rounds is the maximum (for example, 15 rounds) for the probability variation big hit for the other symbol. And a game specification in which a minimum (for example, two rounds) is included at a predetermined ratio (for example, 4: 1).

  In such a background, the following problems are likely to occur in a configuration in which a table for each symbol is provided as in a known gaming machine. In other words, when setting the ratio of different big hit rounds by design or changing the rate later, create multiple tables for each design and modify each existing table. So, we have to make a match between the two. For this reason, the work related to the construction and correction of the table is very complicated, and work mistakes are likely to occur. In particular, when correcting a plurality of existing tables, a great deal of labor is required for the work of matching the tables before and after the correction. In extreme cases, the programmer may modify only one table and forget to modify the other table.

  Therefore, according to the present invention, even in a gaming machine having a plurality of symbols, different types of winning symbols (for example, those having different numbers of big hit rounds) can be easily distributed according to symbols, and the distribution rate can be changed. It is intended to provide a technology that can be reliably performed.

The present invention employs the following means in order to solve the above problems.
Solution 1: The gaming machine according to the present invention has an element acquisition means for acquiring a lottery element and a type determination element for each event, triggered by the occurrence of the first event or the second event during the game, and the element acquisition means. The event-specific storage means for storing the lottery element and the type determination element acquired by the above in accordance with the first event or the second event that triggered the acquisition up to a predetermined upper limit number, and the lottery stored in the event-specific storage means Based on the element, according to the first event or the second event that triggered the acquisition, a symbol-specific lottery execution means for executing an internal lottery corresponding to a predetermined first symbol or symbol, and symbol-specific lottery execution When the internal lottery is performed by the means, after the corresponding first or second symbol is variably displayed, the symbol display means for stopping and displaying the first or second symbol in a manner representing the result of the internal lottery, and the internal lottery Obtained in When selecting a plurality of types of winning symbols to be stopped and displayed by the symbol display means for each corresponding first or second symbol, and the internal lottery from which the winning is obtained corresponds to the first symbol In the case of corresponding to the second symbol, the winning symbol storage means for individually assigning and storing the type of winning symbol for each type determining element, and when winning by the internal lottery by the lottery executing means, Based on the stored type determination element, select one of a plurality of types of winning symbols stored in the winning symbol storage means for the first or second symbol corresponding to the internal lottery from which the winning was obtained. And a winning symbol determining means for automatically determining.

  The gaming machine of the present invention displays the result of the internal lottery using at least two symbols (first symbol, second symbol). The internal lottery may be performed corresponding to the first symbol or may be performed corresponding to the second symbol. Which symbol is used for the internal lottery depends on the event that triggered the acquisition of the lottery element. That is, when using a lottery element acquired in response to the occurrence of the first event, the internal lottery corresponding to the first symbol is used. On the other hand, when using a lottery element acquired in response to the occurrence of the second event, the symbol in the second symbol is used. Corresponding internal lottery. Note that the lottery element (and the type determining element) is stored for each event that triggers the acquisition (in association with the first event or the second event). When the conditions for executing the internal lottery (for example, the lottery element is stored and all symbols are unchanged), the internal lottery is executed based on the lottery element read from the memory. Is done. Then, after the symbol corresponding to the internal lottery is variably displayed, the symbol is stopped and displayed in a manner representing the result of the lottery.

  In the gaming machine of the present invention, even if the winning is obtained by internal lottery, if the type of the winning symbol that is stopped and displayed (stop display mode) is different, the profit that the player can obtain by winning (or given to the player) The size and content of the profits) may vary. For this reason, in the present invention, the difference in the type of winning symbol corresponds not only to the difference in the stop display mode by the symbol display means, but also to the difference in the type or type of winning obtained in the internal lottery. Further, “determining the type of winning symbol” includes determining “what type of winning the result of the internal lottery corresponds to”.

  In addition, in the gaming machine of the present invention, when winning is obtained by internal lottery, based on the type determination element acquired together with the lottery element, one of the types of winning symbols stored in the winning symbol storage means is selected. Selectively. At this time, the type determining element is handled in common in the first symbol and the second symbol for the storage by the winning symbol storage means, but the allocation of the winning symbol to the type determining element is the same in the first symbol and the second symbol. It is done individually. Therefore, for example, the same type of winning symbol can be assigned and stored for one type determining element in the first symbol and the second symbol, or different types of winning symbols can be assigned and stored. You can also In the former case, the result (the type of winning symbol) is the same regardless of whether the winning is performed by the internal lottery corresponding to either the first symbol or the second symbol. On the other hand, in the latter case, the result (the type of winning symbol) differs depending on whether the winner is won by the internal lottery corresponding to the first symbol or the second symbol.

  In this way, if a difference is made in the allocation of the types of winning symbols in advance for each of a plurality of symbols, a variety of games can be realized. For example, for the second symbol, only the winning symbol of the type that maximizes the profit received by the player is allocated, whereas in the first symbol, not only the type of profit that the player receives maximum is allocated, but also the profit Assume that the winning symbol of the type that minimizes is also assigned. In this case, when winning in the internal lottery corresponding to the first symbol, the player may obtain a minimum profit depending on the winning symbol selected at that time. When such a game specification (specification depending on the stored contents of the winning symbol storage means) is adopted for the gaming machine of the present invention, the player should win as much as possible with the second symbol rather than the first symbol. Since it is advantageous, it is possible to provide a game property that an important strategy for advancing the game is to generate as many events (second events) corresponding to the second symbol as possible during the game. For example, if the first event and the second event are generated by winning at different starting points, the player will play a game while paying attention to the winning at the starting point that generates the second event.

  Then, what kind of advantage there is in the form of memory adopted in the present invention is convenience when the basic game specifications are changed and executed. That is, on the memory of the winning symbol storage means, the type of winning symbol is assigned by symbol, but the memory of the type determining element for the symbol is shared (common) between the first symbol and the second symbol, so the following The following advantages are produced.

(1) For example, when the probability variation ratio of a gaming machine is set depending on the content stored in the type determination element (such as a comparison value or a range of random numbers that is a numerator of probability), the content stored in the type determination element on storage By changing / modifying, it is possible to easily change only the probability variation ratio without particularly changing the allocation for each symbol. Further, since the type determining element is common to the first symbol and the second symbol in terms of storage, it is not necessary to check whether the stored contents of the type determining element are consistent for each symbol. Note that “probability ratio” is a type that gives a player an opportunity to shift to a “high probability state” in which the winning probability of the internal lottery is changed higher than usual when a winning is obtained by the internal lottery. This is the ratio at which the winning symbol is selected.

(2) In addition, for a certain content type determining element (for example, a certain comparison value or a range of a certain random value), the winning symbol of the same type in the first symbol and the second symbol until then. (For example, the 15-round probability variation symbol) is assigned, the basic game specification is “The same result (15-round probability variation jackpot) will be obtained regardless of whether the first symbol or the second symbol is won, The probability variation ratio depends on the stored contents of the type determining element (range of random values). From this state, if you change the winning symbol only for the first symbol on the memory of the winning symbol storage means to another type (for example, 2-round probability variation symbol), you can easily change the basic game specifications without changing the probability variation ratio. (Ratio of the number of different rounds by design) can be changed. The game specification in this case is “the rate of probability change is the same, but a result of greater profit is obtained by winning with the second symbol than when winning with the first symbol”. Even if such a game specification change is made, the stored contents of the type determining element (which determines the probability variation ratio) are shared between the first symbol and the second symbol, so the probability variation ratio is consistent for each symbol. There is no need to check if it is.

  Solution 2: Also, in the solution 1, the winning symbol storage unit is different in type corresponding to the first symbol and in the case corresponding to the second symbol for the type determination element having the same contents. The winning symbols may be individually assigned and stored. Note that “same content” here means that the storage of type determination elements (comparison value, range of random values, etc.) is shared between the first symbol and the second symbol for the storage of the winning symbol allocation. Means that

  In this case, as described above, by providing a difference in the amount of profit received by the player according to the type of winning symbol, it is possible to provide as much variety as possible. In addition, even if the probability variation ratio at the time of winning is set depending on the content of the type determination element (range of random values that determines the numerator of probability) as described above, the content of the type determination element in memory Can be easily rearranged into a game specification in which the probability variation ratio is changed as a whole without worrying about the consistency between the first symbol and the second symbol.

  Solution 3: In Solution 1, the gaming machine according to the present invention is a special game that is different from normal when the first or second symbol is stopped and displayed in any kind of winning symbol by the symbol display unit. The special game execution means for executing the special game to which the condition is applied, and the amount of profit that the player should receive during the execution of the special game by the special game execution means are the types of winning symbols displayed by the symbol display means. You may further provide the profit setting means according to a pattern set differently according to it. In this case, the winning symbol storage means is set by the symbol-specific profit setting means depending on whether the internal lottery corresponds to the first symbol or the second symbol with respect to the winning species determining element having the same content. It is preferable that the winning symbols of different types of profits are individually assigned and stored.

  In this case, even if it corresponds to either the 1st symbol or the 2nd symbol, if it wins in the internal lottery and the 1st symbol or 2nd symbol is stopped and displayed in the mode of the winning symbol as a result, The gaming machine of the invention executes a special game and gives a profit to the player. As a benefit that a player can enjoy during this special game, there is generally one that a special winning opportunity is given. Special prize opportunities include, for example, a special variable prize device that does not operate during normal operation, and opens a special prize opening (large prize opening) multiple times (for example, a prescribed number of prizes during one opening) Or when about 30 seconds elapses, one release is ended, and such an opening operation is continuously performed about 15 times at a constant interval). When such special winning opportunities are granted, players can frequently generate winnings that do not occur during normal times, thereby gaining many winning benefits (such as paying out game media) per hour. can do.

  In addition, the solution means 3 provides a difference in the amount of profit that the player can enjoy during the special game, according to the type of winning symbol stopped and displayed at the time of winning. For example, some special games have virtually no chance of winning a prize and end within a relatively short time. Even if such a special game is executed, The profits received are relatively small. In the example of the special variable winning device described above, the time during which the winning opening is opened is extremely short, or the number of times of opening is extremely small. “Extremely short time” means, for example, in the case of a pachinko game machine in which game balls are continuously fired to play a game, the winning opening is opened more than the interval (time interval) at which the game balls are fired one by one. Means that the time is shorter. In such a short period of time, it is difficult to win a game ball substantially, and unless it happens that the game ball was flowing down to the nearest position at the timing just before the release, It is difficult to occur. Further, “the number of times is extremely small” means, for example, the minimum number (= 2 times) of more than once. In this way, during special games where almost no chance of winning a prize is given, either a prize will be generated or no prize will be generated at all. The profits that can be made are smaller. Alternatively, even if the special prize opening is long enough (for example, about 30 seconds), the number of times the special prize opening is opened during the special game is less than the maximum number (for example, at most Also, in the case where the number of times is 15 times), the profit that the player can enjoy is smaller than the maximum number of times.

  Therefore, for example, if a winning symbol of a type that increases the profit in the special game is assigned to the second symbol rather than the first symbol in memory for the type determining element having the same content, it corresponds to the first symbol. A player who wins with the second symbol is more profitable for the player than winning with the internal lottery. As a result, as described above, it is possible to give the player the motivation to “preferentially change the symbol that gives a more advantageous result”, thereby providing diversity to the game content. . Even in this case, the stored content of the type determining element is shared (common) between the first symbol and the second symbol, so even if the stored content is modified to change the game specifications, There is no need to check the consistency of each.

  Solution 4: In Solution 3, the gaming machine according to the present invention is configured so that when the first or second symbol is stopped and displayed in the form of a specific type of winning symbol by the symbol display unit, the special game is executed by the special game executing unit. High-probability state transition means for shifting to a high-probability state in which the probability of internal lottery by the symbol-by-design lottery execution means is changed to be higher than normal after completion may be further provided. In this case, when the internal lottery corresponds to the first symbol, the winning symbol storage means sets the profit set by the symbol-specific profit setting means for the winning symbol determining element having the same content. When the winning symbol of the type with the smallest size is allocated, while the internal lottery corresponds to the second symbol, the profit size set by the symbol-specific profit setting means is the largest among the selected types of winning symbols. It is preferable that a winning symbol of a type larger than the minimum is assigned and stored.

  According to the solution 4, when a specific type of winning symbol is stopped and displayed for both the first symbol and the second symbol, the player is given an opportunity to shift to a high probability state after the special game is over. . Therefore, even if the profit that can be enjoyed during the special game is extremely small, the internal lottery is performed under conditions (high probability) advantageous to the player after the special game is finished, so that the merit can be enjoyed there. it can. In the “high probability state”, in addition to the fact that the winning probability of the internal lottery is changed to be higher than normal as described above, the average symbol variation time is shortened compared to the normal time (time reduction state) ) A privilege may be added.

  Moreover, in the solution means 4, the following patterns can be mentioned as the stored contents of the winning symbol storage means.

(1) A specific type of winning symbol (probability variation) is assigned to both the 1st symbol and the 2nd symbol, but for the 1st symbol, the one with the extremely small profit in the special game is allocated among the specific types. As for the second pattern, those with relatively large profit (or the largest profit) are allocated.

(2) In (1) above, the player is clearly instructed (or suggested, disclosed, or notified) that the second symbol is a “probable variation” in terms of performance at the time of stop display. In addition, when a stop display is made, the player is concealed from the fact that it is a “probable variation” in the production, and the player is instructed in the production that it is a “probability variation” during the special game. Two types are assigned.

(3) A specific type of winning symbol (probability variation) is assigned to both the 1st symbol and the 2nd symbol, but for the 1st symbol, only those with extremely small profits during special games are allocated. As for the second pattern, two types are assigned: one with relatively large profit (or the largest profit) and medium profit.

  The above patterns (1) to (3) are merely examples, and are not particularly limited thereto. The “specific type” winning symbol referred to in the present invention may be a non-probable variable symbol (normal symbol). In any case, in the gaming machine of the present invention, it is easy to modify and change the stored contents of the winning symbol storage means, and it is not necessary to worry about the consistency between symbols one by one. The stored contents can be easily adapted to the game specifications.

  Solution 5: The gaming machine of the present invention has a function as at least an element acquisition means, an event-specific storage means, a symbol-specific lottery execution means, a symbol display means, and a winning symbol determination means in any of the solution means 1 to 4. A main control computer that executes a control program for fulfilling the control is provided. The main control computer functions as an element acquisition unit while generating at least first numerical data and second numerical data in a predetermined order from an initial value to a final value within each numerical value range. Therefore, the process which acquires the 1st and 2nd numerical data as a lottery element and a kind determination element, respectively, is triggered by the occurrence of the first or second event. The numerical data may be generated using hardware (for example, a random number generator), or may be generated (updated) on software as the program is executed.

  Further, the main control computer has a comparison value to be compared with the second numerical data in order from a predetermined head address and a type of the winning symbol corresponding to the first symbol in order to fulfill the function as the winning symbol storing means. 1 judgment data and 2nd judgment data indicating the type of winning symbol corresponding to the 2nd symbol, 1 byte each, for a plurality of comparison values having different values step by step for each storage area of 3 bytes in total A memory for storing a data table to which the first determination data and the second determination data are respectively assigned is included.

  Further, the main control computer compares the comparison value read from the head address of the data table with the execution of the control program with the second numerical value data in order to fulfill the function as the winning symbol determination means. When the data is less than the comparison value and the internal lottery corresponds to the first symbol, the first determination data is selected from the address obtained by adding 1 to the head address, while the second numerical data is the comparison value If the internal lottery corresponds to the second symbol, the process (1) for selecting the second determination data from the address obtained by adding 2 to the head address is executed.

  Alternatively, in the process (1), the comparison value read from the head address is compared with the second numerical data, and if the second numerical data is equal to or greater than the comparison value, the main control computer The comparison value read from the next-stage address obtained by adding 3 to the second numerical data is compared, the second numerical data is less than the comparison value, and the internal lottery matches the first symbol. When it corresponds, the first determination data is selected from the address obtained by adding 1 to the next-stage address, while the second numerical data is less than the comparison value, and the internal lottery corresponds to the second symbol. In this case, a process (2) for selecting the second determination data from the address obtained by adding 2 to the next stage address is executed.

  Alternatively, in the process (2), the comparison value read from the next stage address is compared with the second numerical data, and if the second numerical data is equal to or greater than the comparison value, the main control computer further The comparison value read from the new next stage address obtained by adding 3 to the next stage address is compared with the second numerical data, the second numerical data is less than the comparison value, and When the internal lottery corresponds to the first symbol, the first determination data is selected from the address obtained by adding 1 to the new next stage address, while the second numerical data is less than the comparison value, and When the internal lottery corresponds to the second symbol, the process (3) for selecting the second determination data from the address obtained by adding 2 to the new next stage address is executed.

  If the comparison value read from the new next-stage address in the process (3) is compared with the second numerical data, and the second numerical data is greater than or equal to the comparison value, then the main control computer Repeats the process of sequentially adding 3 to the address to read the comparison value and comparing it with the second numerical data. Here, it is determined whether it is “less than the comparison value” or “more than the comparison value”, but this is used to determine whether it is “less than the comparison value” or “greater than the comparison value”. It may be replaced.

  According to the solution means 5, the stored contents of the winning symbol storage means are [1] comparison value, [2] first determination data, [3] information of 3 bytes up to the second determination data as one set, and repeated memory It is constructed as a data table stored in the storage area. For the comparison value [1], for example, a plurality of data whose values increase stepwise is prepared in advance, and for each of the values, the first determination data [2] and [3 The second determination data is assigned as a set.

  In this case, due to the physical configuration of the data table, the comparison value of the first stage is stored at the head address (for 1 byte), and the comparison of the first stage is performed at the next address (head address +1). The first determination data indicating the winning symbol for the first symbol assigned to the value is stored. In the next address (first address + 2), second determination data indicating the winning symbol for the second symbol assigned to the first comparison value is stored. If the storage area so far (3 bytes, 3 addresses) is one set, the next stage comparison value (head address +3), which is the fourth from the top address, stores the comparison value of the next stage. The first judgment data assigned to the comparison value of the next stage is assigned to the fifth address (next stage address + 1), and the second judgment is assigned to the sixth address (next stage address + 2). Each data is stored. Similarly thereafter, [1] comparison value, [2] first determination data, and [3] second determination data are repeatedly stored in the memory every 3 bytes and 3 addresses.

  Process (1): Therefore, when the main control computer determines the winning symbol, first the data (comparison value) is read from the head address of the data table, and this is the second numerical data (for example, jackpot symbol random number) As a result, if the numerical data is less than the comparison value, this time, the value (1 or 2) for each symbol is added to the leading address, and the second address from the leading address for the first symbol. For the second symbol, by reading the stored contents of the third address from the head address, it is possible to select the determination data indicating the winning symbol of the first symbol or the second symbol.

  Process (2): If the numerical data is equal to or greater than the first comparison value in the above process (1), the main control computer skips the judgment data stored in the set with the first comparison value (to the first address). 3) and move to the next stage address. Then, the next stage comparison value is read again and compared with the numerical data. If it is less than the comparison value, the main control computer adds the value for each symbol to the next stage address, and from there the appropriate value Read judgment data.

  Process (3): If the numerical data is equal to or greater than the comparison value in the above process (2), the main control computer skips the comparison value read in process (2) and the determination data stored as a set ( 3 is added to the next stage address), and the next stage address is newly transferred. Then, the next stage comparison value is read again and compared with the numerical data, and if it is less than the comparison value, the main control computer adds the value for each symbol to the new next stage address, and from there Read appropriate judgment data.

  As described above, the main control computer repeats the processes (1), (2), (3),... Until the second numerical data becomes less than the comparison value on the data table, and the numerical data becomes the comparison value. If it is less than that, the type of winning symbol can be determined by selecting the comparison value and the determination data stored in the set. Thereby, the time required for the process of selecting the winning symbol can be shortened and the processing efficiency can be improved. Further, since the structure of the data table is very simple (repetition of the necessary minimum number of data), the memory usage capacity can be reduced accordingly.

  Moreover, as already described in the solving means 1 to 4, when the basic game specifications are changed, if the storage of the comparison value is changed on the data table, the first determination data stored in a set with this About the 2nd determination data, the content of the comparison value after a change can be reflected simultaneously. For this reason, it is not necessary to check the consistency of symbols after the change, and the number of programming work steps can be reduced accordingly.

  According to the gaming machine of the present invention, the allocation of the winning symbols of the first symbol and the second symbol to the type determining element is stored in one storage means (data table), and the allocation is performed for each symbol. Even if the stored content of the type determining element is changed or the allocation of the winning symbol to the same type determining element is changed for each symbol, it is possible to reliably prevent the inconsistency between symbols. In addition, since the work load required to correct or change the stored contents is reduced, it is possible to proceed with product development with a variety of game specifications easily in a short period of time, thereby greatly contributing to the activation of the game industry.

[Overall configuration of gaming machine]
The pachinko machine 1 mainly includes an outer frame unit 2, a glass frame unit 4, a tray unit 6 and a gaming machine frame (not shown) as its main body. Among these, the outer frame unit 2 is fixed to an island facility (not shown) in the game hall using a fastener such as a screw. The other glass frame unit 4, the tray unit 6, and a gaming machine frame (not shown) are attached to the island facility via the outer frame unit 2, and these operate in an openable manner via a hinge mechanism (not shown). An opening / closing axis of a hinge mechanism (not shown) extends in the vertical direction along the left end as viewed from the front of the pachinko machine 1.

  The above is a configuration example relating to the control of the pachinko machine 1. Next, control processing executed by the main control CPU 72 of the main controller 70 (main control computer) will be described.

[Reset start (main) processing]
When the pachinko machine 1 is powered on, the main control CPU 72 starts a reset start process. The reset start process restores the gaming state based on the backup information saved at the previous power shutdown (so-called power recovery) or conversely clears the backup information, thereby adjusting the initial state of the pachinko machine 1 Process. The reset start process is positioned as a main process (main control program) for guaranteeing a stable gaming operation of the pachinko machine 1 after adjusting the initial state.

  3 and 4 are flowcharts showing an example of the procedure of the reset start process. Hereinafter, the process performed by the main control CPU 72 will be described step by step.

  Step S101: First, the main control CPU 72 sets the top address of the stack area in the stack pointer.

Step S102: Subsequently, the main control CPU 72 sets the vector-type interrupt mode (mode 2) and corrects the default RST-type interrupt mode (mode 0). Thus, thereafter, the main control CPU 72 can refer to an arbitrary address (however, the least significant bit is 0) as an interrupt vector and execute a designated interrupt handler.
Step S103: The main control CPU 72 performs initial setting of the mask register.

  Step S104: The main control CPU 72 refers to the input signal from the previously cleared RAM clear switch and confirms whether or not the RAM clear switch has been operated (switch ON). If the RAM clear switch is not operated (No), next, Step S105 is executed.

  Step S105: The main control CPU 72 checks whether backup information is stored in the RAM 76, that is, whether a backup validity determination flag is set. If the backup ends normally in the previous power-off process and the backup validity determination flag (for example, “A55AH”) is set (Yes), then the main control CPU 72 executes step S106.

  Step S106: The main control CPU 72 executes a sum check on the backup information in the RAM 76. If the check result is normal (Yes), the backup validity determination flag is reset (for example, “0000H”), and then the main control CPU 72 executes step S107.

  Step S107: The main control CPU 72 executes an effect control return process. In this process, the main control CPU 72 transmits a return command to the effect control device 94. In response to this, the effect control device 94 restores the effect state (for example, the display mode of the effect symbol, the sound output content, the light emission state of various lamps, etc.) that was being executed at the time of the previous power shutdown.

  Step S108: The main control CPU 72 executes state return processing. In this processing, based on the backup information, the main control CPU 72 is a game state that was being executed at the time of the previous power shutdown (for example, special symbol display mode, internal probability state, operation memory content, various flag states, random number update state) Etc.). Then, the backed up PC register value is restored, and the processing is continued from the program address.

  On the other hand, when the RAM clear switch is operated at power-on (step S104: Yes), when the backup validity determination flag is not set (step S105: No), or when the backup information is not normal. (Step S106: No), the main control CPU 72 proceeds to Step S109.

  Step S109: The main control CPU 72 clears the stored contents of the RAM 76. Thereby, even if the backup information is stored in the RAM 76, the contents are deleted.

  Step S110: The main control CPU 72 also clears the command transmission request buffer secured in the buffer area of the RAM 76.

  Step S111: The main control CPU 72 executes an effect control output process. In this process, the main control CPU 72 outputs a command to be transmitted to the effect control device 94 after reset (command necessary for effect control).

  Step S112: The main control CPU 72 executes a CTC initialization process, and initializes a CTC (counter / timer circuit) that is a peripheral device. Then, the main control CPU 72 shifts to the main loop shown in FIG. 4 (connection symbol A → A).

  Step S113, Step S114: The main control CPU 72 executes the power interruption occurrence check process after prohibiting interruption. In this process, for example, a signal input from a power supply monitoring IC that is a peripheral device is referenced to monitor the occurrence of power interruption (decrease in supply voltage). When the power is cut off, the main control CPU 72 saves the register, backs up the entire contents of the RAM 76, and stops the processing (NOP). If the power is not shut off, the main control CPU 72 next executes step S115. There is also a known programming example in which the CPU executes the process at the time of the occurrence of power interruption as a non-maskable interrupt (NMI) process.

  Step S115: The main control CPU 72 executes an initial value update random number update process. In this process, the main control CPU 72 increments random numbers for updating (changing) initial values of various software random numbers. In this embodiment, various random numbers are generated on the program in addition to the big hit decision random number. These software random numbers are updated by a loop counter within a predetermined range in another interrupt process (step S201 in FIG. 5). In this process, the initial value of the loop counter is changed every time the random number value makes one round. doing. The initial value update random number is used to randomly change the initial value, and in step S115, the initial value update random number is updated. Note that the reason why step S115 is executed after the interruption is prohibited in step S113 is that the same process is executed in another interrupt process (step S202 in FIG. 5), and therefore overlap (conflict) with this. It is for preventing.

  Step S116, Step S117: The main control CPU 72 permits interruption and executes other random number update processing. The random numbers updated by this process are random numbers (reach determination random numbers, variation pattern determination random numbers, etc.) that are not involved in the determination of the jackpot type among software random numbers. This process is performed during the remaining time when a timer interrupt occurs during execution of the main loop and an interrupt management process described later is executed.

  Step S118: Next, the main control CPU 72 refers to the value of the interrupt counter, and determines whether or not the interrupt processing executed so far has exceeded a predetermined number (for example, twice). If the value of the interrupt counter does not exceed the predetermined value (No), the main control CPU 72 returns to step S113. On the other hand, if the value of the interrupt counter exceeds a predetermined value (Yes), the main control CPU 72 next executes step S119. As a result, at least two timer interrupts are generated during execution of the main loop, and the interrupt management process described later is executed. Further, the main control CPU 72 shuts off the power at the remaining time when the timer interrupt occurs. Generation check processing (step S114) and initial value update random number update processing (step S115) are executed.

  Step S119, Step S120: The main control CPU 72 executes an effect control output process. In this process, the main control CPU 72 outputs a command to be transmitted to the effect control device 94 (command necessary for effect control). The main control CPU 72 clears the port output request buffer secured in the buffer area of the RAM 76.

  Step S121: Next, the main control CPU 72 executes prize ball payout processing. In this process, a prize ball is awarded to the prize ball payout control device 92 based on the winning detection signals input from the various prize opening switches 80, 82, 84, 86 in another interruption process (step S203 in FIG. 5). A prize ball instruction command for instructing the number is output.

  Step S122, Step S123: The main control CPU 72 executes a special symbol game process and a normal symbol game process in the main loop. These processes are for specifically proceeding with the game in the pachinko machine 1. Among these, in the special symbol game process, the main control CPU 72 controls the variable display and stop display by the first and second special symbol display devices 34 and 36 described above, or the variable winning device 30 of the variable winning device 30 according to the display result. Control the operation. In the normal symbol game process, the main control CPU 72 controls the variable display and stop display by the normal symbol display device 33 described above, and controls the operation of the variable start winning device 28 according to the display result. For example, the main control CPU 72 stores a random number (ordinary random number per symbol) acquired in response to the passage of the start gate 20 in another interrupt management process (FIG. 5). Then, the main control CPU 72 reads out the random number value in the normal symbol game process and determines whether or not it falls within a predetermined hit range. When the random number value falls within the hit range, the normal symbol display device 33 displays the normal symbol in a variable manner and displays the stop of the normal symbol in a predetermined hit state. Then, the variable start winning device 28 is operated. On the other hand, if the random number value is out of the hit range, the main control CPU 72 performs a normal symbol stop display in a manner of deviation after the variable display. Details of the special symbol game process will be described later with reference to another flowchart.

  Step S124: Next, the main control CPU 72 executes external information processing. In this process, the main control CPU 72 outputs the above external information to the hall computer in the game hall through the external terminal board.

  Step S125: The main control CPU 72 executes test signal processing in the main loop. In this process, the main control CPU 72 generates a test signal indicating its own internal state (for example, during a big hit, when the probability variation function is activated, when the time shortening function is activated, or when an error is occurring), and this is output to the outside of the main controller 70. Output to. With this test signal, for example, the internal state of the main control CPU 72 can be tested outside the main controller 70.

  Step S126: Next, the main control CPU 72 executes an output management process. In this process, the port output request buffer secured in the buffer area of the RAM 76 is referred to, and the excitation states (ON or OFF) of various solenoids (the lower start opening solenoid 88 and the big winning opening solenoid 90) are output to the output port. .

  In this embodiment, an example in which the processes of steps S119 to S126 are incorporated in the main loop is given, but there is a known programming example in which the CPU executes the processes as a timer interrupt process.

[Interrupt management processing (timer interrupt processing)]
Next, interrupt management processing (timer interrupt processing) will be described. FIG. 5 is a flowchart illustrating an exemplary procedure of interrupt management processing. The main control CPU 72 executes an interrupt management process every predetermined time (for example, several milliseconds) based on the interrupt request signal from the counter / timer circuit. Each procedure will be described below.

  Step S200: First, the main control CPU 72 saves the values of the registers (accumulator A, flag register F, and general-purpose registers B to L) used during execution of the main loop in the save area of the RAM 76. Another value is written in the registers (A to L) after the value is saved during the interrupt management process.

  Step S201: Next, the main control CPU 72 executes a lottery random number update process. In this process, the main control CPU 72 updates the value of the counter for generating various random numbers for lottery. The value of each counter is incremented in the counter area of the RAM 76 and loops within a specified range. The various random numbers include, for example, jackpot symbol random numbers, normal symbol random numbers determined, and the like. Of these, the jackpot symbol random number is numerical data (second numerical data) that is sequentially updated in a range of 0 to 99, for example. In this embodiment, since the two symbols of the first special symbol and the second special symbol are used, a big hit symbol random number may be generated for each of these symbols. In this case, an initial value update random number may be prepared for each symbol.

  Step S202: The main control CPU 72 executes the initial value update random number update process also here. The content of the process is the same as described above.

  Step S203: The main control CPU 72 executes input processing. In this process, the main control CPU 72 inputs various switch signals from an input / output driver (PIO). Specifically, the passage detection signal from the gate switch 78, and the input state (ON / OFF) of the winning detection signal from the upper starting winning port switch 80, the lower starting winning port switch 82, the large winning port switch 84, and the winning port switch 86 are displayed. OFF).

  Step S204: Next, the main control CPU 72 executes switch input event processing. In this process, among the switch signals input in the previous input process, an event occurring during the game is determined based on detection signals from the gate switch 78, the upper start winning port switch 80, and the lower starting winning port switch 82. Depending on the event that has occurred, further processing is executed.

  In this embodiment, when a winning detection signal (ON) is input from the upper start winning opening switch 80, the main control CPU 72 generates an event (first event) that triggers an internal lottery corresponding to the first special symbol. Is determined. The main control CPU 72 determines that an event (second event) that triggers an internal lottery corresponding to the second special symbol has occurred when the winning detection signal (ON) is input from the lower start winning a prize opening switch 82. . When the passage detection signal (ON) is input from the gate switch 78, the main control CPU 72 determines that an event serving as a lottery trigger corresponding to the normal symbol has occurred. If it is determined that any event has occurred, the main control CPU 72 executes a process corresponding to each event. The processing executed when a winning detection signal is input from the upper start winning port switch 80 or the lower starting winning port switch 82 will be described later with reference to another flowchart.

  Step S205: Next, the main control CPU 72 executes display output management processing. In this process, the main control CPU 72 performs the normal symbol display device 33, the normal symbol operation memory lamp 33a, the first special symbol display device 34, the second special symbol display device 36, the first operation memory lamp 34a, and the second operation memory lamp 36a. The lighting state of the game state display device 38 and the like is controlled. Specifically, a drive signal (byte data) to be applied to each LED is generated and output from the output port. As a result, each LED is driven in a predetermined display mode (a mode of performing symbol variation display, stop display, working memory number display, game state display, etc.).

  Step S206: When the above processing is completed, the main control CPU 72 updates the interrupt counter. This counter is referred to in step S118 in the main loop described above.

  Steps S207 and S208: Then, the main control CPU 72 restores the saved values of the registers (A to L) and permits the interrupt. Thereafter, the main control CPU 72 returns to the main loop (program address indicated by the stack pointer).

[Start-up winning process]
Next, processing that is further executed in the switch input event processing (step S204) will be described. FIG. 6 is a flowchart illustrating a procedure example of the start winning process. Each procedure will be described below.

  Step S10: The main control CPU 72 confirms whether or not a winning detection signal is input from the upper start winning opening switch 80 corresponding to the first special symbol. When the input of the winning detection signal is confirmed (Yes), the main control CPU 72 executes the next step S12.

  Step S12: The main control CPU 72 refers to the value of the first special symbol working memory number counter to check whether the working memory number is less than four. The working memory number counter represents the number of jackpot determination random numbers and jackpot symbol random numbers (number of sets) stored in the random number storage area of the RAM 76. That is, the random number storage area of the RAM 76 is divided into four sections (for example, 2 bytes each) for each symbol (first special symbol, second special symbol), and each section contains a big hit decision random number and a big hit symbol random number. Each can be stored as a set. At this time, if the number of stored jackpot determined random numbers and jackpot symbol random numbers corresponding to the first special symbol does not reach four, the value of the first special symbol working memory number counter is less than 4 (Yes), In this case, the main control CPU 72 proceeds to the next step S14.

  Step S14: The main control CPU 72 adds one first special symbol working memory number. The first special symbol operation memory number counter is stored, for example, in a counting area of the RAM 76, and the main control CPU 72 increments (+1) the value. Based on the counter value added here, the lighting state of the first operation memory lamp 34a is controlled in the display output management process (step S205 in FIG. 5).

  Step S16: Then, the main control CPU 72 acquires a jackpot determination random number value (first numerical data) corresponding to the first special symbol from the random number generator 75 through the sampling circuit 77 (acquisition of lottery elements). The random value is acquired by specifying the pin address of the random number generator 75. In the case where the main control CPU 72 performs 8-bit processing, the address designation is performed twice for each upper byte and lower byte. When the main control CPU 72 reads the jackpot determination random number value from the designated address, it saves it as a jackpot determination random number corresponding to the first special symbol at the transfer source address.

  Step S17: Next, the main control CPU 72 acquires a jackpot symbol random number value (second numerical data) corresponding to the first special symbol from the counter area of the RAM 76 (acquisition of the type determining element). In this case, the random value is acquired by designating the address of the RAM 76. When the main control CPU 72 reads the jackpot symbol random number value from the designated address, it saves it as a jackpot symbol random number corresponding to the first special symbol at the transfer source address.

  Step S18: The main control CPU 72 transfers the saved jackpot decision random number and the jackpot symbol random number to the random number storage area corresponding to the first special symbol, and stores these random numbers as a set in an empty section in the area (store by event). means). The order (for example, first to fourth) is set in the plurality of sections. If all the first to fourth sections are empty at this stage, the random numbers are stored in order from the first section. Alternatively, if the first section is already filled and the other second to fourth sections are empty, the random numbers are stored in order from the second section.

  Step S20: The main control CPU 72 sets a first special symbol start opening prize flag. When the main control CPU 72 returns to the main loop, it refers to the value of the flag set here and transmits a start opening winning tone control command to the effect control device 94, and also gives a prize ball instruction to the prize ball payout control device 92. Send a command.

  When the above procedure is completed, or when no winning detection signal is input from the upper start winning opening switch 80 (step S10: No), or when the first special symbol operating memory number has reached 4 (step S12). : No), the main control CPU 72 then executes step S22.

  Step S22: The main control CPU 72 confirms whether or not a winning detection signal has been input from the lower start winning opening switch 82 corresponding to the second special symbol. If the input of the winning detection signal is not confirmed (No), the main control CPU 72 returns to the interrupt management process. On the other hand, when the input of the winning detection signal is confirmed (Yes), the main control CPU 72 executes the next step S24.

  Step S24: The main control CPU 72 refers to the value of the second special symbol working memory number counter to check whether the working memory number is less than four. Similarly to the above, the second special symbol operation memory number counter represents the jackpot determination random number and the number of jackpot symbol random numbers (the number of sets) stored in the random number storage area of the RAM 76. At this time, if the value of the second special symbol operation memory number counter reaches 4 (No), the main control CPU 72 returns to the interrupt management process. On the other hand, if the value of the second special symbol operation memory number counter is still less than 4 (Yes), the main control CPU 72 proceeds to the next step S26.

  Step S26: The main control CPU 72 increments the second special symbol operation memory number by one (increments the value of the second special symbol operation memory number counter).

  Step S28: The main control CPU 72 acquires a jackpot determination random number value (first numerical data) corresponding to the second special symbol from the random number generator 75 (acquisition of lottery elements). The method for acquiring the random value is the same as that in step S16 described above.

  Step S29: Next, the main control CPU 72 acquires a jackpot symbol random number value (first numerical data) corresponding to the second special symbol from the counter area of the RAM 76 (acquisition of type determining element). The method for acquiring the random value is the same as that in step S17 described above.

  Step S30: The main control CPU 72 transfers the saved jackpot decision random number and the jackpot symbol random number to the random number storage area corresponding to the second special symbol, and stores them in the empty section in the area as a set (memory for each event) ). The storage method is the same as step S18 described above.

  Step S32: The main control CPU 72 sets a second special symbol start opening prize flag. When the above procedure is completed, the main control CPU 72 returns to the interrupt management process.

[Special design game processing]
Next, the details of the special symbol game process executed during the main loop will be described. FIG. 7 is a flowchart showing a configuration example of the special symbol game process. The special symbol game process includes an execution selection process (step S1000), a special symbol change pre-process (step S2000), a special symbol change process (step S3000), a special symbol stop display process (step S4000), and a big hit game process (step S5000) subroutine group. Here, first, the basic flow of the special game management process will be described along each process.

  Step S1000: In the execution selection process, the main control CPU 72 selects a jump destination of a process to be executed next (any one of steps S2000 to S5000). For example, the main control CPU 72 designates the program address of the process to be executed next, and sets the end of the special symbol game process in the “jump table” as the jump destination and return address. Which process is selected as the next jump destination depends on the progress of the processes performed so far. For example, if both the first special symbol and the second special symbol have not yet started to be changed, the main control CPU 72 selects the special symbol change pre-process (step S2000) as the next jump destination. On the other hand, if the special symbol change pre-processing has already been completed, the main control CPU 72 selects the special symbol changing process (step S3000) as the next jump destination, and if the special symbol changing process has been completed, For example, the special symbol stop display processing (step S4000) is selected as the jump destination. In this embodiment, the jump destination address is specified by the “jump table” and the process is selected. However, apart from such a selection method, a “process flag”, a “process selection flag”, or the like is used. There is also a known programming example in which the CPU selects a process to be executed next. In such a programming example, the CPU CALLs each process in a single way, and at the top step, the conditional branch (continuation / return) is performed with reference to the flag one by one. There is no need for the CPU 72 to call each process one by one.

  Step S2000: In the special symbol variation pre-processing, the main control CPU 72 performs an operation of preparing conditions for starting the variation display of the first special symbol or the second special symbol. The specific processing content will be described later using another flowchart.

  Step S3000: In the special symbol variation processing, the main control CPU 72 performs drive control of the first special symbol display device 34 or the second special symbol display device 36 while counting the variation timer. Specifically, an ON or OFF drive signal (1 byte data) is output for each segment and dot (0th to 7th) of the 7-segment LED. The pattern of the driving signal changes with the passage of time, and thereby, the variation display of the first special symbol or the second special symbol is performed.

  Step S4000: In the special symbol stop display process, the main control CPU 72 performs drive control of the first special symbol display device 34 and the second special symbol display device 36. Similarly, an ON or OFF drive signal is output for each segment and dot of the 7-segment LED, but the drive signal pattern is constant, thereby stopping the display of the first special symbol and the second special symbol. Is done.

  Step S5000: The jackpot game process is selected when the first special symbol or the second special symbol is stopped and displayed in a big hit manner in the previous special symbol stop display process. When either the first special symbol or the second special symbol is stopped in the big hit display mode, the normal state is changed to the big hit gaming state (a gaming state advantageous to the player). During the big hit game, the big prize opening solenoid 90 is energized a predetermined number of times (for example, 15 times) for a predetermined time (for example, 30 seconds or until nine winnings are counted) in the big hit game processing, thereby the variable winning device 30 is Open operation with a fixed pattern (continuous operation of special electric accessory). In the meantime, by allowing the variable winning device 30 to win the game balls intensively, the player is given an opportunity to collect a lot of prize balls (special game execution means). The opening operation of the variable winning device 30 is referred to as “round”, and if the prescribed number of times is 15 in total, this may be collectively referred to as “15 round”. When the big hit game ends, the main control CPU 72 sets a game state flag indicating the state after the big hit game (high probability state, time reduction state). When the “high probability state” is reached, the probability variation function is activated, and the probability that the next jackpot will occur is higher (approximately 10 times) than usual (high probability state transition means). Further, when the “high probability state” is reached, the time shortening function is activated, and the variation time of the first special symbol or the second special symbol is reduced as a whole.

  In the present embodiment, the first special symbol and the second special symbol are provided as symbols relating to the big winning internal lottery in order to provide the following gaming characteristics, for example. That is, in this embodiment, the magnitude of the profit given to the player is different between the case where the first special symbol is stopped in the jackpot display mode and the case where the second special symbol is stopped in the jackpot display mode. Cases are provided. Such a difference in the magnitude of profit is realized, for example, by providing a difference in the type of winning symbol between the first special symbol and the second special symbol (design-specific profit setting means). Hereinafter, this point will be described.

[Setting example of different number of rounds by design]
For both the first special symbol and the second special symbol, the ratio that the jackpot type is “probability variation jackpot”, that is, the probability variation ratio is the same (for example, about 50% is “probability variation jackpot”). However, for the first special symbol, “probability variation jackpot” is set to be a jackpot of “2 rounds” (for example, about 10% of 50%). The big hit of “2 rounds” is a relatively short opening time per time (for example, about 0.3 seconds), and after a single opening operation, a predetermined interval (for example, about 1 to 2 seconds) is set. The second opening operation is performed, and the process ends only by that. For this reason, even if it becomes a big hit of “2 rounds”, the winning in the big winning opening does not occur or the winning of one game ball is barely generated, and the player can be won during the big hit. It can be said that there are almost no prize balls.

  On the other hand, for the second special symbol, all “probability variation jackpots” are jackpots of “15 rounds”. In this case, the opening time per time is relatively long (until 30 seconds or 9 winnings are counted as described above), and when a single opening operation ends, a predetermined interval (for example, about 1 to 2 seconds) ), And after performing the opening operation for 15 times, the big hit game ends. For this reason, when the “15 round” is a big hit, the winning prizes are intensively generated, so that the player receives a relatively large number of winning balls in a short time (for example, 14 payouts per winning prize). Can be earned.

  For this reason, from the player's point of view, the overall profit is greater for the second special symbol than for the first special symbol. Of course, for the first special symbol, the “probability variation jackpot” may be a jackpot of “15 rounds” (for example, about 40% of 50%), but may be a jackpot of “2 rounds”. For some reason, it is easier to feel a sense of security for a big hit with the second special symbol than a big hit with the first special symbol. Therefore, the pachinko machine 1 according to the present embodiment realizes a game property that “it is an important strategy for advancing the game to launch the game ball with the aim of winning the game ball in the lower start opening 28a as much as possible”. doing.

  However, the setting of the number of rounds as described above is merely an example, and the playability by the pachinko machine 1 is the type of winning symbol (winning type, winning type) for the first special symbol and the second special symbol, respectively. It depends on what ratio is allocated. For example, conversely to the above example, if the first special symbol does not have a “two rounds” jackpot, and the second special symbol has only a “two rounds” jackpot, this time the reverse The pachinko machine 1 will have a completely different game characteristic that “it is advantageous to avoid winning the lower start opening 28a as much as possible”.

  In the present embodiment, both the first special symbol and the second special symbol are assumed on the assumption that the example of the gaming specification given first (example in which only the first special symbol has a “2 round” jackpot) is adopted. When there is a working memory, the appeal of the player is enhanced by variably displaying the second special symbol in preference to the first special symbol. Hereinafter, a control method that prioritizes the variable display of the second special symbol will be described. Note that such control is not essential for the implementation of the present invention, and it is possible to adopt a control for evenly varying display of either symbol, or conversely, the first special symbol may be preferentially varied and displayed. Good.

[Special symbol change pre-treatment]
FIG. 8 is a flowchart showing an example of the procedure of special symbol variation pre-processing. Hereinafter, it demonstrates along each procedure.

  Step S2100: First, the main control CPU 72 checks whether or not the first special symbol working memory number or the second special symbol working memory number remains (greater than 0). This confirmation can be made with reference to the value of the working memory number counter stored in the RAM 76. When the number of working memories of both the first special symbol and the second special symbol is 0 (No), the main control CPU 72 executes a demonstration setting process in step S2500.

  Step S2500: In this process, the main control CPU 72 generates a demonstration effect command. The demonstration effect command is output to the effect control device 94 in the effect control output process (step S119 in FIG. 4). When the demo setting process is executed, the main control CPU 72 returns to the special symbol game process.

  On the other hand, if the value of any of the working memory number counters is greater than 0 (Yes), the main control CPU 72 next executes step S2200.

  Step S2200: The main control CPU 72 executes special symbol storage shift processing after prohibiting interruption. In this process, the main control CPU 72 preferentially reads out the lottery random numbers (big hit determination random number, big hit symbol random number) stored in the random number storage area of the RAM 76, which corresponds to the second special symbol. At this time, if random numbers are stored in two or more sections, the main control CPU 72 sequentially reads the random numbers from the first section, and moves (shifts) the remaining random numbers one by one to the previous section. Only when the random number corresponding to the second special symbol is not stored, the random number corresponding to the first special symbol is read and stored in another common storage area. Each random number stored in the common storage area is used for internal lottery in the next jackpot determination process. As a result, in the present embodiment, the variable display of the second special symbol is preferentially performed over the first special symbol.

  Step S2250: Next, the main control CPU 72 executes a special symbol operating memory number subtraction process. In this process, the main control CPU 72 subtracts one value of the working memory number counter (which corresponds to either the first special symbol or the second special symbol) stored in the RAM 76, and obtains the value after the subtraction. Set to “Number of working memories at start of change”. At this time, the working memory number counter to be subtracted corresponds to the one on which the random number stored in the previous step S2200 has been shifted. As a result, the display mode of the number stored by the first operation memory lamp 34a or the second operation memory lamp 36a changes (decreases by 1) in the display output management process (step S205 in FIG. 5). When the procedure so far is finished, the main control CPU 72 permits the interrupt and then executes step S2300.

  Step S2300: The main control CPU 72 executes a big hit determination process (internal lottery). In this process, the main control CPU 72 sets a range of the big hit value and determines whether or not the read random number value is included in this range. The range of the jackpot value set at this time is different between the normal state and the high probability state (probability variation state). In the high probability state, the range of the jackpot value is expanded to about 10 times that of the normal state. At this time, if the read random number value is included in the range of the big hit value, the main control CPU 72 sets the big hit flag (01H), and then proceeds to step S2400. In this embodiment, the jackpot value is determined by setting a range of the jackpot value on the program. However, the jackpot determination table is written in the ROM 74 in advance, and the jackpot determination is performed by reading this and comparing it with the random number value. There are also programming examples.

  Here, as described above, since the big hit determination random number value is read separately for the first special symbol or the second special symbol, the big hit determination process (internal lottery) is performed for each symbol. For example, if the random number value corresponding to the first special symbol is read in the previous step S2200, the jackpot determination is performed corresponding to the first special symbol. On the other hand, if the random number value corresponding to the second special symbol is read out, the big hit determination is performed corresponding to the second special symbol (designated lottery execution means). Here, in order to prioritize the variation of the second special symbol, it is assumed that the random number value corresponding to the second special symbol is read in step S2200.

  Step S2400: The main control CPU 72 determines whether or not a value (01H) is set for the big hit flag in the previous big hit determination process. If the value (01H) is not set in the jackpot flag (No), the main control CPU 72 next executes step S2404.

  Step S2404: The main control CPU 72 executes an off-time stop symbol determination process. In this process, the main control CPU 72 confirms whether the current fluctuation display corresponds to the first special symbol or the second special symbol, and sets the stop symbol number data at the time of the loss for the corresponding special symbol. To do. Specifically, if the big hit determination random number corresponding to the second special symbol and the big hit symbol random number have been preferentially shifted in the previous special symbol memory shift process, the main control CPU 72 displays the second special symbol display here. Stop symbol number data by the device 36 is set. On the other hand, if the memory of the big hit determination random number corresponding to the first special symbol is shifted, the main control CPU 72 sets the stop symbol number data by the first special symbol display device 34 here. The main control CPU 72 also generates a stop symbol number command and a lottery result command (at the time of loss) to be transmitted to the effect control device 94. These commands are transmitted to the effect control device 94 in the effect control output process (step S119 in FIG. 4).

  In this embodiment, since the 7-segment LED is used for each of the first special symbol display device 34 and the second special symbol display device 36, for example, the display mode of the stop symbol at the time of disconnection is always set to one segment (the center It is possible to fix the stop symbol number data to a common value (for example, 64H) for both symbols by only turning on the bar “-”). In this case, the storage capacity used in the program can be reduced, the processing load on the main control CPU 72 can be reduced, and the processing speed can be improved.

  Step S2406: Next, the main control CPU 72 executes a deviation variation pattern determination process. In this process, the main control CPU 72 determines the variation pattern number of the special symbol at the time of detachment for the first special symbol or the second special symbol. The variation pattern number is used to distinguish the variation display type (pattern) of the first special symbol or the second special symbol, or to correspond to the variation time required for the variation display. Except when the reach variation is performed, the variation time at the time of losing is determined based on, for example, “variable display start operation memory number (0 to 3)” set in step S2250.

  The above steps S2404 and S2406 are control procedures when the big hit determination result is out of order, but when the determination result is big hit (step S2400: Yes), the main control CPU 72 executes the following procedure.

  Step S2410: The main control CPU 72 executes a big hit stop symbol determination process. In this process, the main control CPU 72 determines the type of winning symbol (hit-stopping symbol number) for the first special symbol or the second special symbol that is won in the current internal lottery, based on the jackpot symbol random number. The relationship between the jackpot symbol random number value and the type of winning symbol for each symbol is defined in advance in the special symbol determination data table. For this reason, the main control CPU 72 can determine the type of winning symbol for each symbol based on the jackpot symbol random number based on the stored content by referring to the special symbol determination table in the symbol determination process for big hit. The detailed contents of the big hit stop symbol determination process will be described later with reference to another drawing together with the example of the special symbol determination data table.

  Step S2412: Next, the main control CPU 72 executes a hit variation pattern determination process. In this process, when the main control CPU 72 obtains the variation pattern determination random number from the counter area of the RAM 76, the main control CPU 72 determines the variation pattern (variation time) of the first special symbol or the second special symbol based on the value. Further, the main control CPU 72 sets the determined variation time value in the variation timer. Basically, since the hit hit fluctuation is performed at the time of hitting, if the reach determining random number is not used in this process, the acquisition of the reach determining random number may be omitted. In general, in the case of big hit reach fluctuation, a fluctuation time longer than that at the time of losing is determined.

  Step S2413: The main control CPU 72 determines the type of “probability variation symbol” or “non-probability variation (normal) symbol” based on the winning symbol type (big hit stop symbol number) determined in the previous step S2410, In the case of “probable variation”, a value (01H) is set in the probability variation flag. Further, the main control CPU 72 sets the number of rounds (2, 5, 15) during the big hit based on the type of winning symbol (stop symbol number at the time of big hit). The number of rounds set here is used in the big hit game process (step S5000 in FIG. 7).

  In step S2413, the main control CPU 72 determines the display mode of the stop symbol (big hit symbol) by the first special symbol display device 34 or the second special symbol display device 36 based on the big hit time stop symbol number. The main control CPU 72 also generates a stop symbol command and a lottery result command (at the time of a big hit) to be transmitted to the effect control device 94. The stop symbol command and the lottery result command are also transmitted to the effect control device 94 in the effect control output process.

  Step S2414: Next, the main control CPU 72 executes special symbol variation start processing. In this process, the main control CPU 72 selects the fluctuation pattern data based on the fluctuation pattern number (out of time / hit), and sets the fluctuation time value corresponding to the fluctuation pattern in the fluctuation timer. At the same time, the main control CPU 72 sets the variation start flag of the first special symbol or the second special symbol in the flag area of the RAM 76. Then, the main control CPU 72 generates a change start command to be transmitted to the effect control device 94. This variation start command is also transmitted to the effect control device 94 in the effect control output process. When the above procedure is completed, the main control CPU 72 returns to the special symbol game process.

[Figure 7: Special symbol change processing, special symbol stop display processing]
When returning to the special symbol game process, the main control CPU 72 sets the special symbol changing process (step S3000) as the next jump destination. In the special symbol variation processing, the main control CPU 72 loads the value of the variation timer from the register to the timer counter as described above, and then decrements the value of the timer counter as time elapses (clock pulse count). . The main control CPU 72 controls the variable display of the first special symbol or the second special symbol as described above until the value becomes 0 while referring to the value of the timer counter. When the value of the timer counter becomes 0, the main control CPU 72 sets the special symbol stop display in-progress process (step S4000) as the next jump destination.

  In the special symbol stop display process, the main control CPU 72 controls the stop display of the first special symbol or the second special symbol based on the stop symbol determined in the stop symbol determination process (steps S2404 and S2410 in FIG. 8). To do. The main control CPU 72 generates a symbol stop command to be transmitted to the effect control device 94. The symbol stop command is transmitted to the effect control device 94 in the effect control output process. When the stop symbol is displayed for a predetermined time in the special symbol stop display process, the main control CPU 72 deletes the symbol changing flag.

[Big-hit stop symbol determination processing: winning symbol determination means]
Next, FIG. 9 is a flowchart showing in detail a procedure example of the big hit stop symbol determination process. Hereinafter, the details of the processing will be described along each procedure.

  Step S500: The main control CPU 72 first sets “1” in the lower byte of the table offset value. This offset value is a value for offsetting an address when data is loaded on the special symbol determination data table. The table offset value will be further described later.

  Step S502: Next, the main control CPU 72 confirms whether or not the internal lottery in which the current winning (big win) is obtained corresponds to the second special symbol. Specifically, in the case where the jackpot determination random number and the jackpot symbol random number corresponding to the second special symbol are preferentially shifted in the previous special symbol memory shift process (step S2200 in FIG. 8), the main control CPU 72 Confirms that the current internal lottery corresponds to the second special symbol (Yes), and then proceeds to step S504.

  Step S504: The main control CPU 72 adds “1” to the lower byte of the table offset value set in the previous step S500. As a result, the lower byte of the table offset value is updated to “2”.

  Step S506: Next, the main control CPU 72 sets the address of the special symbol determination data table. The special symbol determination data table is stored in the table area of the ROM 74. Here, the head address of the special symbol determination data table in the ROM 74 is set to the table address of the current reading destination.

[Special symbol determination data table (1): winning symbol storage means]
FIG. 10 is a diagram showing an example of the special symbol determination data table (1) used in the big hit stop symbol determination process. In this data table, for example, “comparison value”, “first special symbol determination data (first determination data)”, and “second special symbol determination data (second determination data)” are each 1 byte in order from the head address. In this structure, a total of 3 bytes of data is stored in one set (for each stage). The “comparison value” is stored in the first (first) address among the 3 bytes, “first special symbol determination data” is stored in the second address, and “second special symbol is stored in the third address. Each of the “determination data” is stored.

  The “comparison value” is provided with four different values “50”, “70”, “90”, and “0FFH”, and the “first special symbol” for each “comparison value”. Determination data "and" second special symbol determination data "are assigned in order. Specifically, “000H” and “000H” are assigned to “50”, which is the smallest value among the comparison values that differ in stages. In the next stage, “001H” and “001H” are assigned to “70”, respectively. In the next stage, “002H” and “002H” are assigned to “90”, and “003H” and “001H” are assigned to the maximum value “0FFH”. Yes. Note that “0FFH” is for preventing the main control CPU 72 from running out of control when comparing numerical values on a program.

[Type of winning design]
The above-mentioned “first special symbol determination data” and “second special symbol determination data” are merely numerical data on the table, but in the program, each of these determination data includes the type of winning symbol, that is, the jackpot type (Big hit type) is assigned in advance. For example, in the special symbol determination data table (1), the winning symbol is assigned to each determination data as follows.

“000H”: 15 round non-probable (normal) design “001H”: 15 round probable design (1)
"002H": 15 round probability variation (2)
“003H”: 2-round probability variation

  Note that the “15-round probability variation (1)” and “15-round probability variation (2)” are basically the same, but they differ in the way in which the player is presented (corresponding performance pattern). Yes. That is, in this embodiment, since the first special symbol display device 34 and the second special symbol display device 36 are 7-segment LEDs, the player instantly determines the type of winning symbol simply by looking at the stop display mode. It is difficult (in fact, the display mode is difficult to judge visually). For this reason, when a player determines the type of winning symbol, the content of the production is relied upon exclusively.

  For example, for “15 round probability variable symbol (1)”, “3”-“3”-“3” corresponding to the probability variable symbol at the time of stop display by the first special symbol display device 34 or the second special symbol display device 36. The effect symbol D is displayed on the liquid crystal display 40 by the combination of (see FIG. 1 as appropriate). In this case, the player is clearly informed of the “15-round probability variation symbol” depending on the content of the performance.

  On the other hand, in the case of “15 round probability variation symbol (2)”, a combination of non-probability variation symbols (for example, “4”-“ 4 ”-“ 4 ”) is displayed, and the player performs an effect of the content of being promoted to a probable big jackpot during the big hit game (for example, displaying character information such as“ promotion of probable big hit ”). Teach that. By giving such a performance, the player was given a disappointing impression that he had missed the probable big hit, and later he was surprised and delighted that he was promoted to probable big hit. An effect to make it appear is obtained.

[See Fig. 9: Big hit stop symbol determination process]
Step S508: When the top address of the special symbol determination data table is set as the current reading destination in the previous step S506, the main control CPU 72 designates the table address and loads the comparison value. Specifically, the main control CPU 72 loads “50” from the head address of the special symbol determination data table (1).

  Step S510: The main control CPU 72 compares the comparison value with the jackpot symbol random number value, and determines whether or not the jackpot symbol random number value is within the range of the comparison value (less than the comparison value). As a result, if the jackpot symbol random number is equal to or greater than the comparison value (No), the main control CPU 72 then proceeds to step S512.

  Step S512: The main control CPU 72 adds “3” to the table address. Then, the added address is set as the current reading destination, and the process returns to step S508. In this case, an address obtained by adding 3 to the head address of the special symbol determination data table becomes a new table address of the current reading destination.

  Step S508: The main control CPU 72 loads the comparison value from the table address set at the current reading destination. In this case, the main control CPU 72 loads the comparison value by designating the next stage (third) address instead of the head address. Therefore, when the special symbol determination data table (1) of FIG. 10 is used, the main control CPU 72 loads “70” as the comparison value at the second stage.

  Thereafter, the main control CPU 72 compares the comparison value with the jackpot symbol random number value at step S510, and if the jackpot symbol random number value is equal to or greater than the comparison value (No), the process proceeds to step S512 and further adds “3” to the table address. To do. Then, when returning to step S508, the address of the next stage is further specified on the table and the comparison value is loaded.

  If the main control CPU 72 determines in step S510 that the jackpot symbol random number value is less than the comparison value in the process of repeatedly executing the processing of step S508 to step S512 (Yes), the process proceeds to step S514.

  Step S514: The main control CPU 72 sets “0” in the upper byte of the table offset value. As a result, “1” or “2” is completed as the table offset value by logically ORing the lower bytes set in the previous steps S500 and S504.

  Step S516, Step S518: The main control CPU 72 adds an offset value ("1" or "2") to the table address set at the current reading destination. Then, the main control CPU 72 acquires determination data from the table address after the addition.

  Step S520: The main control CPU 72 sets the big hit stop symbol number based on the determination data acquired in the previous step S518. When the above procedure is completed, the main control CPU 72 returns to the special symbol fluctuation pre-processing (FIG. 8).

In the following, a description will be given with some selection examples.
[Selection Example 1]
For example, it is assumed that winning is made by an internal lottery corresponding to the first special symbol, and the jackpot symbol random number at that time is any one of “0” to “49”. In this case, the contents of processing by the main control CPU 72 are as follows.

[See Fig. 9: Big hit stop symbol determination process]
In step S502, the main control CPU 72 determines that the internal lottery corresponds to the first special symbol (No), bypasses step S504, and proceeds to step S506. In this case, the lower byte of the table offset value remains “1”. If it is confirmed in step S510 that the jackpot symbol random number value is less than the comparison value (Yes), the table offset value is completed to “1” in step S514, and the address obtained by adding 1 to the head address in the next step S516. Load judgment data from (second).

[See FIG. 10: Special Symbol Determination Data Table (1)]
In this case, the main control CPU 72 designates the second address of the table and acquires “000H” from the storage area. As a result, for the first special symbol, “15 round non-probable variation” is selected as the type of winning symbol.

[Selection Example 2]
Next, selection example 2 will be described. For example, it is assumed that winning is made by an internal lottery corresponding to the second special symbol, and the jackpot symbol random number at that time is one of “0” to “49”. In this case, the contents of processing by the main control CPU 72 are as follows.

[See Fig. 9: Big hit stop symbol determination process]
The main control CPU 72 determines in step S502 that the internal lottery corresponds to the second special symbol (Yes), and adds “1” to the lower byte of the table offset value in the next step S504. In this case, the lower byte of the table offset value is “2”. When it is confirmed in step S510 that the jackpot symbol random number is less than the comparison value (Yes), the table offset value is completed to “2” in step S514, and the address obtained by adding 2 to the top address in the next step S516. Load judgment data from (third).

[See FIG. 10: Special Symbol Determination Data Table (1)]
In this case, the main control CPU 72 designates the third address of the table and acquires “000H” from the storage area. As a result, for the second special symbol, the above-mentioned “15 round uncertain variation” is selected as the type of winning symbol.

[Selection Example 3]
Similarly, for example, when the internal lottery corresponding to the first special symbol is won, and the jackpot symbol random value at that time is less than the comparison value of the next stage, that is, from “50” to “69”, The main control CPU 72 acquires “001H” as the determination data. In this case, “15 round probability variation (1)” is selected as the type of winning symbol for the first special symbol. Selection example 3 gives the same result for the second special symbol.

[Selection Example 4]
Alternatively, when the jackpot symbol random number is less than the comparison value of the next stage, that is, any of “70” to “89”, the main control CPU 72 acquires “002H” as the determination data. In this case, “15 round probability variation (2)” is selected as the winning symbol type for the first special symbol. Selection example 4 also has the same result for the second special symbol.

[Selection example 5: First special symbol]
When the jackpot symbol random number is less than the comparison value at the final stage in the table, that is, between “90” and “99”, the main control CPU 72 acquires “003H” as the determination data. In this case, “2-round probability variation symbol” is selected as the type of winning symbol for the first special symbol.

[Selection Example 6: Second special symbol]
On the other hand, when the internal lottery corresponding to the second special symbol is won and the jackpot symbol random number is any one of “90” to “99”, the main control CPU 72 acquires “001H” as the determination data. In this case, for the second special symbol, “15 round probability variation symbol (1)” is selected as the type of winning symbol. In this case, different types of winning symbols are selected for the first special symbol and the second special symbol even if the acquired jackpot symbol random values are the same.

[Usefulness of special symbol determination data table (1)]
Here, mention is made of the usefulness of the special symbol determination data table (1) employed in the present embodiment.

(1) When the probability variation ratio is changed In the current special symbol determination data table (1), the proportion of non-probability variation symbols is set with the minimum comparison value “50”, so the probability variation ratio (50%) depends on this. Is set. Therefore, if the comparison value “50” is changed to a smaller value, the proportion of the non-probable variation in the whole is reduced, and the probability variation ratio can be changed relatively high. On the contrary, if the minimum comparison value is changed to a value larger than “50”, the probability variation ratio can be changed accordingly. In any case, the stored content of both the first special symbol determination data “000H” and the second special symbol determination data “000H” is simply changed in the table to the stored content of the comparison value “50”. Changes will be involved at the same time. For this reason, it is not necessary to confirm whether or not the probability variation ratio is consistent among the symbols in the changed table, and the program can be easily corrected accordingly.

(2) When the ratio of the number of rounds is changed In the current special symbol determination data table (1), the first special symbol has a ratio of 20% to “15 round probability variable symbol (1)” and “15 round probability variable symbol (2 ) ”And“ 2 Round Probability Variations ”are distributed at the remaining 10%, but“ 15 Round Probability Variation (1) ”is distributed at 30% for the second special symbol. “15 rounds probable variation (2)” is distributed at the rate of the remaining 20%. For the comparison value “0FFH”, the memory of “2 round probability variation symbol” is allocated in the first special symbol, whereas the memory of “15 round probability variation symbol (1)” is allocated in the second special symbol. This is because they are assigned.

  From this state, for example, if the determination data of the second special symbol for the comparison value “0FFH” is rewritten from “001H” to “003H” in the table, the second special symbol is also at the same rate as the first special symbol. The number of rounds can be distributed, and the ratios of “15 round probability variation symbol (1)” and “15 round probability variation symbol (2)” can also be completely matched between symbols. In this case, since the minimum comparison value “50” is not changed, the probability variation ratio itself does not change. In this way, in the special symbol determination data table (1), the ratio of the number of rounds can be changed for each symbol by simply rewriting the stored contents of the determination data for a certain comparison value, or conversely, the proportion of the same number of rounds between symbols can be set. Can be easily performed.

  In the present embodiment, various data tables can be applied in addition to the special symbol determination data table (1). Hereinafter, other examples of the data table will be described.

[Special symbol determination data table (2)]
FIG. 11 is a diagram illustrating an example of the special symbol determination data table (2). The data table (2) is provided with five values “50”, “70”, “90”, “95”, and “0FFH” that are different in stages as “comparison values”. Of these, “000H” and “000H” are assigned to “50” which is the smallest value, and “001H” and “001H” are assigned to “70” at the next stage. It has been. In the next stage, “002H” and “002H” are assigned to “90”, and in the next stage, “003H” and “001H” are assigned to “95”. Yes. Then, “003H” and “002H” are assigned to the maximum value “0FFH”. In the special symbol determination data table (2), the winning symbols are assigned to the determination data “000H” to “003H” in the same manner as described above.

  In the case of the special symbol determination data table (2), the comparison values “95” and “0FFH” are all assigned “003H” determination data in the first special symbol, but “001H” in the second special symbol. ”,“ 002H ”. For this reason, when the jackpot symbol random number value is within the same range (90 to 99), the “2 round probability variation symbol” is always distributed in the first special symbol, but the “15 round probability variation symbol (1) in the second special symbol. ) ”Or“ 15 round probability variation (2) ”.

  Even when the special symbol determination data table (2) is used, it is possible to realize the same gaming property as in the above embodiment. However, in the special symbol determination data table (2), since the ratio of the “15 round probability variation symbol (2)” selected in the second special symbol is high, the tendency of the production content (the probability variation promotion effect during the big hit) Can be changed).

[Special symbol determination data table (3)]
Next, FIG. 12 is a diagram illustrating an example of the special symbol determination data table (3). In this data table (3), six values “50”, “70”, “90”, “95”, “98”, and “0FFH” that are different in stages are provided as “comparison values”. Among these, the allocation of the determination data to the determination values “50” to “95” is the same as that in the special symbol determination data table (2). “003H” and “002H” are assigned to “98” in the next stage, but “003H” and “004H” are assigned to the maximum value “0FFH”. ing.

  In the special symbol determination data table (3), the winning symbols are assigned to the determination data of “000H” to “003H” in the same manner as described above. For the determination data of “004H”, for example, “5 round probability change” is used. "Design" is assigned. The “5-round probability variation pattern” has 5 rounds of big hits, and the number of winning balls obtained during the big hits is reduced as compared with 15 rounds. However, since the game moves to the high probability state after 5 rounds, the player is given an opportunity to receive an internal lottery under the high probability state. Therefore, if the player can win 15 rounds next time, the player can acquire more prize balls while digesting the 15 rounds.

  In the case of the special symbol determination data table (3), for the comparison values “95”, “98”, “0FFH”, determination data of “003H” is all assigned in the first special symbol, but the second special symbol is assigned. In this case, determination data “001H”, “002H”, and “004H” are respectively assigned. For this reason, when the jackpot symbol random number value is within the same range (90 to 99), the “2 round probability variation symbol” is always distributed in the first special symbol, but the “15 round probability variation symbol (1) in the second special symbol. ) ”,“ 15-round probability variation symbol (2) ”, or“ 5-round probability variation symbol ”.

  For this reason, when the special symbol determination data table (3) is used, it is possible to realize a gameability different from that of the above embodiment. In other words, “2 round probability variation” may be selected for the first special symbol, and “5 round probability variation” may be selected for the second special symbol. There will be a type of winning symbol. For this reason, it is certainly more advantageous for the player to win in the internal lottery corresponding to the second special symbol than to the first special symbol, but it does not mean that anything can be won if it can be won in the second special symbol. And winning as much as possible with the “15 round probability variation” will be the most profitable for me. For this reason, when playing a game with the pachinko machine 1, it is advantageous to change the second special symbol by winning the lower starting prize opening 28a as much as possible, but it is important to allocate more of the 15 round probability variation symbols among them. It becomes possible to realize a game such as “become a good strategy”.

  As described above, according to the present embodiment, the basic game specifications can be diversified according to the stored contents of the special symbol determination data table, thereby realizing various games. In addition, it is easy to change the stored contents of the data table, and it is difficult for the inconsistency between symbols to occur. Therefore, it is possible to change the game specifications of the pachinko machine 1 at a low cost within a short period of time. It is possible to provide products of other varieties to the market in a shorter cycle. From the player's point of view, if a wide variety of game specifications are available, you will be attracted to the pachinko machine 1 and you can select the one that suits your taste from various game specifications. There is an advantage that you can.

  In the present embodiment, the special symbol determination data tables (1) to (3) exemplified above can be used as appropriate. In this case, various playability can be given according to the pattern of the table mounted on the pachinko machine 1, and the range of variation development as a product can be expanded accordingly.

  In addition, in the special symbol determination data tables (2) and (3), it is possible to easily achieve consistency between symbols when changing the probability variation ratio, and when changing the ratio of the number of rounds, different proportions are set for each symbol. Or matching the proportions between symbols can be easily performed.

  The present invention can be implemented with various modifications without being limited to the above-described embodiment. In one embodiment, a different number of rounds is assigned only for the probability variation symbol, but a different number of rounds can be allocated for the non-probability variation symbol. For example, on the special symbol determination data table, the first special symbol has a distribution of “2-round non-probable (normal) symbol” and “15 round non-probable (normal) symbol”, but the second special symbol “ Only “15 round non-probable (normal) symbols” can be assigned.
