Next, the game in the gaming machine 100 of the present embodiment will be described together with various tables stored in the main ROM 300b.

As described above, in the gaming machine 100 of the present embodiment, two types of games, a special game and a normal game, proceed in parallel, and a low-probability gaming state is defined as a gaming state when both of these games are advanced. Alternatively, the game proceeds in any of the gaming states in which any of the high-probability gaming states and the non-time-saving gaming state or the time-saving gaming state are combined.

The details of each game state will be described later, but the low-probability game state is a game state in which the probability of acquiring the right to execute a large role game in which the large winning opening 128 is opened is set low, and the high-probability game state is set. This is a gaming state in which the probability of acquiring the right to perform a major role game is set high.

Further, the non-time-saving game state is a game state in which the movable piece 122b is unlikely to be opened and the game ball is difficult to enter the second starting port 122, and the time-saving game state is compared to the non-time-saving game state. However, the movable piece 122b is likely to be in the open state, and the game ball is likely to enter the second starting port 122. The initial state of the gaming machine 100 is set to a low-probability gaming state and a non-time-saving gaming state, and this gaming state is referred to as a normal gaming state in the present embodiment.

When the player operates the operation handle 112 to launch the game ball into the game area 116 and the game ball flowing down the game area 116 enters the first start port 120 or the second start port 122, the player is allowed to play the game. A lottery for whether or not to give a profit (hereinafter referred to as a "major role lottery") is held. In this big role lottery, if a big hit is won, the big winning opening 128 is opened and a big winning game is executed so that the game ball can enter the big winning opening 128, and after the big winning game is finished. The gaming state is set to any of the above gaming states. The major role lottery method will be described below.

As will be described in detail later, when a game ball enters the first start port 120 or the second start port 122, various random numbers related to the big win lottery (big hit determination random number, hit symbol random number, reach group determination random number, reach). The mode determination random number and the fluctuation pattern random number) are acquired, and each of these random number values is stored in the special figure reservation storage area of the main RAM 300c. In the following, various random numbers stored in the special figure hold storage area when the game ball enters the first start port 120 are collectively referred to as special 1 hold, and the game ball enters the second start port 122. The various random numbers stored in the special figure hold storage area are collectively called special 2 hold.

The special figure reservation storage area of the main RAM 300c includes a first special figure reservation storage area and a second special figure reservation storage area. The first special figure reserved storage area and the second special figure reserved storage area each have four storage units (first to fourth storage units). Then, when the game ball enters the first start port 120, the special 1 hold is stored in order from the first storage unit of the first special figure hold storage area, and when the game ball enters the second start port 122, the special 1 hold is stored. 2 Holds are stored in order from the first storage unit of the second special figure hold storage area.

For example, when a game ball enters the first starting port 120, if the hold is not stored in any of the first to fourth storage units of the first special figure hold storage area, the first storage unit is used. Special 1 Hold is memorized. Further, for example, when a game ball enters the first starting port 120 in a state where the special 1 hold is stored in the first storage unit to the third storage unit, the special 1 hold is set to the fourth storage unit. Remember. Further, even when the game ball enters the second starting port 122, the special 2 hold is stored in the 1st to 4th storage units of the 2nd special figure hold storage area in the same manner as described above. Special 2 hold is stored in the storage unit with the smallest number (ordinal number).

However, the number of special 1 hold (X1) and the number of special 2 hold (X2) that can be stored in the first special figure hold storage area and the second special figure hold storage area are set to four, respectively. Therefore, for example, when the game ball enters the first starting port 120, if four special 1 holdings are already stored in the first special figure holding storage area, the first starting port 120 is entered. No new special 1 hold is memorized by entering the game ball. Similarly, when the game ball enters the second starting port 122, if four special 2 holdings are already stored in the second special figure holding storage area, the game to the second starting port 122 is played. No new special 2 hold is memorized by entering the ball.

FIG. 6 is a diagram illustrating a jackpot determination random number determination table. When a game ball enters the first starting port 120 or the second starting port 122, one jackpot determination random number is acquired from the range of 0 to 65535. Then, when the big win lottery is started, that is, the big hit determination random number determination table is selected according to the game state when the big hit is determined, and the selected jackpot determination random number determination table and the acquired jackpot determination random number are used. A big role lottery will be held.

When starting the big win lottery for the special 1 hold and the special 2 hold in the low probability game state, as shown in FIG. 6A, the low probability big hit determination random number determination table is referred to. According to this low probability jackpot determination random number determination table, if the jackpot determination random number is 10001 to 10164, it is determined to be a jackpot, and if it is another jackpot determination random number, it is determined to be a loss. Therefore, the jackpot probability in this case is about 1 / 399.6.

Further, in the high-probability gaming state, when the big winning combination lottery is started for the special 1 hold and the special 2 hold, as shown in FIG. 6B, the high-probability big hit determination random number determination table is referred to. According to this high-accuracy jackpot-determined random number determination table, if the jackpot-determined random number is 10001 to 11640, it is determined to be a jackpot, and if it is another jackpot-determined random number, it is determined to be a loss. Therefore, the jackpot probability in this case is about 1 / 39.96. As described above, in the high-probability gaming state, the jackpot probability is 10 times higher than in the low-probability gaming state. The jackpot determination random numbers (10001 to 10164) that are "big hits" in the low-probability gaming state are also "big hits" in the high-probability gaming state.

FIG. 7 is a diagram illustrating a winning symbol random number determination table. When a game ball enters the first starting port 120 or the second starting port 122, one winning symbol random number is acquired from the range of 0 to 99. Then, when the determination result of "big hit" is derived by the above-mentioned big role lottery, the type of the special symbol is determined by the acquired winning symbol random number and the winning symbol random number determination table. At this time, when the "big hit" is won by the special 1 hold, the symbol random number judgment table for the special 1 is selected as shown in FIG. 7 (a), and the "big hit" is won by the special 2 hold. As shown in FIG. 7B, a symbol random number determination table for special 2 is selected. In the following, the special symbol determined by the hit symbol random number, that is, the special symbol determined when the jackpot judgment result is obtained is called the jackpot symbol, and the special symbol determined when the loss judgment result is obtained. The design is called a lost design.

According to the special 1 hit symbol random number determination table shown in FIG. 7 (a) and the special 2 hit symbol random number determination table shown in FIG. 7 (b), the figures are shown according to the acquired values of the winning symbol random numbers. As you can see, the type of special symbol (big hit symbol) is determined. In addition, when the large role lottery result is "missing" and the lottery result is derived by holding special 1, special symbol X is determined as a lost symbol without performing a lottery, and the lottery result is special 2 When it is derived by holding, the special symbol Y is determined as the lost symbol without performing a lottery. That is, the winning symbol random number determination table is referred only when the big winning lottery result is "big hit", and is not referred to when the big winning lottery result is "missing".

FIG. 8 is a diagram illustrating a reach group determination random number determination table. A plurality of reach group determination random number determination tables are provided, and one table is selected according to the hold type, the number of holds, and the fluctuation state set in association with the game state. When the game ball enters the first starting port 120 or the second starting port 122, one reach group determination random number is acquired from the range of 0 to 10066. As described above, when the major winning combination lottery result is derived, a process of determining a variable effect pattern for notifying the major winning combination lottery result is performed. In the present embodiment, when the result of the large winning combination lottery is "missing", the group type is first determined by the reach group determination random number and the reach group determination random number determination table in determining the variation effect pattern.

For example, when the game state is set to the non-time saving game state and the fluctuation state is normally set to 1 fluctuation state, when the big role lottery result of "loss" is derived based on the special 1 hold, If the number of special 1 holdings (hereinafter, simply referred to as “holding number”) at the time of performing the big winning combination lottery is 0, the reach group determination random number determination table 1 is selected as shown in FIG. 8A. Similarly, if the number of holds is 1, as shown in FIG. 8 (b), the reach group determination random number determination table 2 is selected, and if the number of holds is 2, or 3, as shown in FIG. 8 (c). As shown, the reach group determination random number determination table 3 is selected. In FIG. 8, the group x described in the group type column indicates an arbitrary group number. Therefore, various group numbers are determined as the group type according to the acquired reach group determination random number and the type of the reach group determination random number determination table to be referred to.

As described above, in the present embodiment, the table for determining the variation effect pattern is determined based on the variation state in addition to the set gaming state. That is, the variable state is a concept in which the table to be referred to to determine the variable effect pattern is defined, and is set separately from the game state.

If the result of the big role lottery is "big hit", the group type is not decided when the variable effect pattern is decided. That is, the reach group determination random number determination table is referred only when the big win lottery result is "miss", and is not referred to when the big win lottery result is "big hit".

FIG. 9 is a diagram illustrating a reach mode determination random number determination table. This reach mode determination random number judgment table is selected when the big role lottery result is "miss", and the reach mode determination random number judgment table at the time of loss, and the big hit selected when the big role lottery result is "big hit". It is roughly divided into the time reach mode determination random number judgment table. The loss time reach mode determination random number determination table is provided for each group type determined as described above, and the jackpot reach mode determination random number determination table is provided for each game state and symbol type. Further, each reach mode determination random number determination table may be provided for each hold type. Here, an example of a lost reach mode determination random number determination table for group x referred to in a predetermined game state and symbol type is shown in FIG. 9A, and an example of a jackpot reach mode determination random number determination table is shown in FIG. 9 (a). Shown in b).

When the game ball enters the first starting port 120 or the second starting port 122, one reach mode determination random number is acquired from the range of 0 to 250. Then, when the result of the above-mentioned major role lottery is "missing", as shown in FIG. 9A, a random number for determining the reach mode at the time of losing corresponding to the group type determined by the above-mentioned group type lottery. The determination table is selected, and the variable mode number is determined based on the selected random number for determining the reach mode at the time of loss and the random number for determining the reach mode. If the result of the above-mentioned big win lottery is "big hit", as shown in FIG. 9B, the big hit reach mode determination random number determination table corresponding to the read game state and the type of symbol Is selected, and the variable mode number is determined based on the selected jackpot reach mode determination random number determination table and the reach mode determination random number.

Further, in each reach mode determination random number determination table, the reach mode determination random number is associated with the variation pattern random number determination table described later together with the variation mode number, and at the same time when the variation mode number is determined, the variation pattern The random number judgment table is determined. In FIG. 9, the table x described in the column of the variation pattern random number determination table indicates an arbitrary table number. Therefore, the variation mode number and the table number of the variation pattern random number determination table are determined according to the acquired reach mode determination random number and the type of the reach mode determination random number determination table to be referred to. Further, in the present embodiment, the variation mode number and the variation pattern number described later are set in hexadecimal. In the following, when a hexadecimal number is indicated, "H" is added, but the description of XXH in FIGS. 9 to 11 indicates an arbitrary value indicated by the hexadecimal number.

As described above, when the result of the large winning combination lottery is "missing", first, the group type is determined by the reach group determination random number determination table and the reach group determination random number shown in FIG. Then, the variation mode number and the variation pattern random number determination table are determined by the reach mode determination random number determination table and the reach mode determination random number shown in FIG. 9 according to the determined group type and the game state.

On the other hand, when the big win lottery result is "big hit", the big hit reach mode determination random number determination table shown in FIG. And the reach mode determination random number, the variation mode number and the variation pattern random number determination table are determined.

FIG. 10 is a diagram illustrating a variation pattern random number determination table. Here, the variation pattern random number determination table x of a predetermined table number x is shown, but in addition to this, a large number of variation pattern random number determination tables are provided for each table number.

When the game ball enters the first starting port 120 or the second starting port 122, one variation pattern random number is acquired from the range of 0 to 238. Then, the variation pattern number is determined as shown in the figure based on the variation pattern random number determination table determined at the same time as the variation mode number and the acquired variation pattern random number.

When the big winning combination lottery is performed in this way, the variable mode number and the variable pattern number are determined according to the big winning combination lottery result, the determined symbol type, the game state, the number of holdings, the holding type, and the like. These variation mode numbers and variation pattern numbers specify the variation effect pattern, and the mode and time of the variation effect are associated with each of them. In the following, the fluctuation mode number and the fluctuation pattern number may be collectively referred to as fluctuation information.

FIG. 11 is a diagram illustrating a fluctuation time determination table. As described above, when the variation mode number is determined, the variation time 1 is determined according to the variation time 1 determination table shown in FIG. 11 (a). According to this variation time 1 determination table, the variation time 1 is associated with each variation mode number, and the corresponding variation time 1 is determined according to the determined variation mode number.

Further, when the fluctuation pattern number is determined as described above, the fluctuation time 2 is determined according to the fluctuation time 2 determination table shown in FIG. 11B. According to the fluctuation time 2 determination table, the fluctuation time 2 is associated with each fluctuation pattern number, and the corresponding fluctuation time 2 is determined according to the determined fluctuation pattern number. The total time of the fluctuation times 1 and 2 determined in this way is the time of the fluctuation effect for notifying the result of the big winning combination lottery, that is, the fluctuation time.

When the variation mode number is determined as described above, the variation mode command corresponding to the determined variation mode number is transmitted to the sub-control board 330, and when the variation pattern number is determined, the determined variation The variation pattern command corresponding to the pattern number is transmitted to the sub-control board 330. In the sub-control board 330, the first half mode of the variation effect is mainly determined based on the received variation mode command, and the second half aspect of the variation effect is mainly determined based on the received variation pattern command. It becomes. In the following, the variable mode command and the variable pattern command may be collectively referred to as a variable command, and the details thereof will be described later.

FIG. 12 is a diagram illustrating a special electric accessory operating ram set table. This special electric accessory actuated ram set table stores various data for controlling the major role game, and during the major role game, the special electric accessory actuated ram set table is referred to to win a large prize. The solenoid 128c is energized and controlled. In reality, a plurality of special electric accessory operating ram set tables are provided for each type of jackpot symbol, and the corresponding table is set at the start of the jackpot game according to the determined type of jackpot symbol. Here, for convenience of explanation, control data of all jackpot symbols is shown in one table.

When the special symbols A to D, which are the jackpot symbols, are determined, as shown in FIG. 12, the jackpot game is executed with reference to the special electric accessory operating ram set table. The big role game is composed of a plurality of round games in which the big winning opening 128 is opened and closed a predetermined number of times. According to this special electric accessory operating ram set table, the opening time (waiting time until the first round game is started) and the maximum number of special electric accessory operating times (round game executed during one major role game). (Number of times), the number of times the special electric accessory opening / closing is switched (the number of times the large winning opening 128 is opened in one round), the solenoid energizing time (the energizing time of the large winning opening solenoid 128c for each opening of the large winning opening 128, that is, 1 Opening time of the large winning opening 128 of each round), specified number (maximum number of winnings to the large winning opening 128 in one round game), effective closing time of the large winning opening 128 (closing time of the large winning opening 128 between round games) That is, the interval time) and the ending time (the waiting time from the end of the last round game to the restart of the normal special game (variation display of the special symbol described later)) are used as control data for the major game. , Each type of jackpot symbol is stored in advance as shown in the figure.

FIG. 13 is a diagram illustrating a game state setting table for setting a game state after the end of a major role game. As shown in FIG. 13, when the special symbol A is determined, it is set to the low probability game state after the end of the big role game, and when the special symbols B to D are determined, the high probability is set after the end of the big role game. The game state is set, and the number of times the high-probability game state is continued (hereinafter referred to as "high probability number") is set to 10,000 times. This means that the high-probability gaming state continues until the result of the big win lottery is confirmed 10,000 times. However, the above-mentioned high-probability number of times indicates the maximum number of continuations in the high-probability gaming state of 1, and if a big hit is won before reaching the above-mentioned number of continuations, the game state is set again. It will be done. Therefore, when the high-probability game state is set after the end of the big role game, if the lottery result of the loss is derived 10,000 times without deriving the lottery result of the big hit in the high-probability game state, the low-probability game is performed. The game state will be changed to the state.

Further, when the special symbol A is determined, it is set to the non-time saving game state after the end of the big role game, and when the special symbols B to D are determined, it is set to the time saving game state after the end of the big role game. At the same time, the number of times the time-saving game state is continued (hereinafter, referred to as "time-saving number of times") is set to 10,000 times. This means that the time-saving game state continues until the result of the big role lottery is confirmed 10,000 times. However, the above-mentioned number of time reductions indicates the maximum number of continuations in the time-saving game state of 1, and if a big hit is won before reaching the above number of continuations, the game state is set again. It will be.

Here, the game state, the number of high accuracy times, and the number of time reductions are set according to the type of the jackpot symbol, but the big role game is set according to both the type of the jackpot symbol and the game state at the time of winning the jackpot. The game state, the number of times of high accuracy, and the number of times of shortening the time may be set after the end of.

FIG. 14 is a diagram illustrating a hit determination random number determination table. When a game ball flowing down the game area 116 passes through the gate 124, a determination process of a normal symbol associated with whether or not to control energization of the movable piece 122b of the second starting port 122 (hereinafter referred to as "general drawing lottery"). ) Is performed.

As will be described in detail later, when the game ball passes through the gate 124, one hit determination random number is acquired from the range of 0 to 99, and four of these random numbers are stored in the normal figure reservation storage area of the main RAM 300c. Is stored as the upper limit. That is, the normal figure reservation storage area includes four storage units for storing the winning determination random numbers. Therefore, when the game ball passes through the gate 124 in a state where the hit decision random number is stored in all four storage units of the normal figure reservation storage area, the hit decision random number is stored based on the passage of the game ball. There is no such thing. In the following, the hit determination random number that the game ball passes through the gate 124 and is stored in the normal figure hold storage area is referred to as a normal figure hold.

When starting the normal drawing lottery in the non-time saving game state, as shown in FIG. 14A, the hit determination random number determination table for the non-time saving game state is referred to. According to this non-time saving game state hit determination random number determination table, when the hit determination random number is 0, the hit symbol is determined as the type of the normal symbol, and when the hit determination random number is 1 to 99, A lost symbol is determined as the type of normal symbol. Therefore, the probability that the winning symbol is determined in the non-time saving game state, that is, the winning probability is 1/100. As will be described in detail later, when the winning symbol is determined in this general drawing lottery, the movable piece 122b of the second starting port 122 is controlled to be in the open state, and when the lost symbol is determined, the second starting port 122 is determined. The movable piece 122b of the above is maintained in the closed state.

Further, when starting the normal drawing lottery in the time-saving game state, as shown in FIG. 14B, the hit determination random number determination table for the time-saving game state is referred to. According to the hit determination random number determination table for the time-saving game state, when the hit determination random number is 0 to 98, the hit symbol is determined as the type of the normal symbol, and when the hit determination random number is 99, it is normal. A lost symbol is determined as the type of symbol. Therefore, the probability that the winning symbol is determined in the time-saving game state, that is, the winning probability is 99/100.

FIG. 15A is a diagram for explaining a normal symbol fluctuation time data table, and FIG. 15B is a diagram for explaining an open / close control pattern table. As described above, when the general drawing lottery is performed, the fluctuation time of the normal symbol is determined. The normal symbol fluctuation time data table is referred to when the fluctuation time of the normal symbol is determined when the winning symbol or the lost symbol is determined by the ordinary symbol lottery. According to this normal symbol variation time data table, the variation time is determined to be 10 seconds when the gaming state is set to the non-time saving gaming state, and varies when the gaming state is set to the time saving gaming state. The time is determined to be 1 second. When the fluctuation time is determined in this way, the normal symbol display 168 is displayed in a variable manner (blinking display) over the determined time. Then, when the winning symbol is determined, the normal symbol display 168 is turned on, and when the lost symbol is determined, the normal symbol display 168 is turned off.

Then, when the winning symbol is determined by the ordinary symbol lottery and the normal symbol display 168 is turned on, the movable piece 122b of the second starting port 122 has an open / close control pattern as shown in FIG. 15 (b). Energization is controlled by referring to the table. Actually, the open / close control pattern table is provided for each game state, and the corresponding table is set at the start of energization of the normal electric accessory solenoid 122c according to the game state when the normal symbol is determined. However, here, for convenience of explanation, control data corresponding to each gaming state is shown in one table.

When the winning symbol is determined, as shown in FIG. 15B, the opening / closing control of the second starting port 122 is controlled with reference to the opening / closing control pattern table. According to this opening / closing control pattern table, the time before opening the normal electric power (waiting time until the opening of the second starting port 122 is started), the maximum number of times of switching the opening / closing of the normal electric accessory (the number of times of opening the second starting port 122). , The solenoid energizing time (the energizing time of the ordinary electric accessory solenoid 122c for each opening number of the second starting port 122, that is, the opening time of the second starting port 122 once), the specified number (the total of the second starting port 122). The maximum number of prizes that can be awarded to the second start port 122 during opening), the normal electric closing effective time (the closing time between each opening of the second starting port 122, that is, the pause time), and the normal electric effective state time (the second start). The second start port is the waiting time from the end of the last opening of the mouth 122) and the waiting time for ending the normal power (waiting time after the lapse of the normal power effective state time until the variable display of the normal symbol described later is resumed). The control data of 122 is stored in advance for each gaming state as shown in the figure.

As described above, the opening / closing control conditions for opening / closing the second start port 122 are associated with the non-time-saving game state and the time-saving game state as the game progress conditions, respectively, and the non-time-saving game state is associated with the non-time-saving game state. It becomes easier for the game ball to enter the second starting port 122 than in the game state. That is, in the time-saving game state, as long as the game ball passes through the gate 124, the drawing lottery is performed one after another, and the second starting port 122 is frequently opened, so that the player consumes the cost of the game ball. It is possible to perform a big role lottery while reducing the number of players.

The opening / closing condition of the second starting port 122 defines three elements: the winning probability of the normal symbol, the time for displaying the fluctuation of the normal symbol, and the opening time of the second starting port 122. Then, in the present embodiment, in two of these three elements, the time-saving game state is set more advantageously than the non-time-saving game state, so that the time-saving game state is more advantageous than the non-time-saving game state. , It is set so that the game ball can easily enter the second starting port 122. However, with respect to one or three of the above three elements, the time-saving gaming state may be set more advantageously than the non-time-saving gaming state. In any case, the time-saving game state is more advantageous than the non-time-saving game state for at least one element, so that the time-saving game state is generally more advantageous than the non-time-saving game state. The game ball may easily enter the 122. That is, when the gaming state is set to the non-time saving gaming state, the movable piece 122b is controlled to open and close according to the first condition, and when the gaming state is set to the time saving gaming state, from the first condition. The opening and closing of the movable piece 122b may be controlled according to the second condition in which the movable piece 122b is likely to be opened.

Next, the display mode of the base display 304 and the calculation method of the base ratio displayed on the base display 304 will be described.

FIG. 16 is a diagram illustrating a display mode of the base display 304. On the main control board 300, the base ratio when the gaming states are the low-probability gaming state and the non-time-saving gaming state is displayed on the base display 304. Here, as will be described in detail later, the base ratio is derived for each preset section (every 60,000 out balls), and the general winning opening 118, the first starting opening 120, and the first starting opening 120 with respect to the number of out balls are derived. 2 The total value (number of payouts) of the number of prize balls paid out when the game ball enters the starting port 122 is shown as a percentage (%).

As shown in FIG. 16, on the base display 304, the base ratio of the current section and the base ratio of the previous section are switched and displayed at preset intervals (for example, 5 seconds).

The base display 304 is a 7-segment display 304a, 304b, and an identifier "bc" or "bb" for identifying whether it is the base ratio of the current section or the base ratio of the previous section is displayed. Further, the base display 304 has 7 segments 304c and 304d, and the base ratio corresponding to the identifier "bc" or "bb" is displayed in two digits.

Therefore, assuming that the base ratio of the current section is 30%, when displaying the base ratio of the current section, "bc" is displayed on the 7-segments 304a and 304b, and "30" is displayed on the 7-segments 304c and 304d. Is displayed. Further, assuming that the base ratio of the previous section is 38%, when displaying the base ratio of the previous section, "bb" is displayed on the 7-segments 304a and 304b, and "38" is displayed on the 7-segments 304c and 304d. Is displayed.

FIG. 17 is a diagram illustrating a section of the base ratio displayed on the base display 304. Here, between the time when the gaming machine 100 is manufactured and the time when the gaming machine 100 is installed in the hall and the game is played by the player, an inspection at the time of manufacturing, a test run (operation check) in the hall, and the like are performed. Game balls will be fired and ejected during such inspections during manufacturing and test runs in halls, but if the number of out balls and the number of ejects during this period are counted, the game will be played by the player. There is a risk that it will not be possible to accurately derive the base ratio during the period.

Therefore, as shown in FIG. 17A, the first section (non-target section) in which the total number of out balls detected by the out ball detection switch 129s is 0 to 300 is inspected at the time of manufacturing or in a hall. Exclude from the target for deriving the base ratio as an out ball detected before the game by the player such as a test run. Similarly, the number of payouts paid out in the section where the number of out balls is 0 to 300 is also excluded from the target for deriving the base ratio. In this non-target section, as shown in FIG. 17B, when displaying the base ratio of the current section, the identifier "bc" is blinked and the base ratio is lit up as "---". do. Further, since the previous section does not exist, when displaying the base ratio of the previous section, the identifier "bb" is blinked and the base ratio is lit up as "---".

Then, the number of out balls from 301 to 60300 is set as the first section, and in the first section, the base ratio is derived at any time (in real time), and when displaying the base ratio of the current section, the identifier "bc" is used. "Is displayed, and the derived base ratio is lit up. At this time, while the number of out balls is from 301 to 6299 (while the number of out balls in the section is 5999 or less), the identifier "bc" is blinked and displayed to derive the base ratio of the current section. Notify that the sample is small and the base ratio is not stable. After that, when the number of out balls becomes 6300 or more (the number of out balls in the section becomes 6000 or more), there are many samples for deriving the base ratio of the current section by lighting and displaying the identifier "bc". , Notifies that the base ratio is stable.

In addition, since the previous section does not exist in the first section, when displaying the base ratio of the previous section, the identifier "bb" is blinked and the base ratio is lit up as "---". do.

Further, in the second section where the number of out balls is 60301 to 120300, the base ratio is derived at any time (in real time) as in the first section, and when the base ratio of the current section is displayed, it is out. The identifier "bc" is lit or blinking according to the number of balls, and the derived base ratio is displayed. Further, in the second section, when displaying the base ratio of the previous section, the identifier "bb" is lit and displayed, and the final base ratio of the first section is lit and displayed.

In this way, the base ratio derived in real time is displayed as the base ratio of the current section every 60000 (every nth section) excluding the first 300 out balls, and the n-1th time. The final base ratio of the section of is displayed as the base ratio of the previous section.

As a result, the number of out balls and the number of discharged balls before the game by the player, such as inspection at the time of manufacturing and test run (operation check) in the hall, can be excluded from the target for deriving the base ratio. The ratio can be derived accurately.

When deriving the base ratio, the base ratio may temporarily exceed 100%. For example, when the first ball in the section enters the first starting port 120, the number of out balls is 1, while the number of payouts is the prize ball obtained by entering the first starting port 120. It becomes a number (for example, 3), and the base ratio is 300%. In such a case, since the base display 304 can display the base ratio only in two digits, it is notified that the base ratio exceeds 100% by lighting and displaying "99.".

FIG. 18 is a diagram illustrating a method of calculating the base ratio. In FIG. 18, the base ratio is derived assuming that the number of payouts is “3456” and the number of out balls is “10000”.

As described above, the base ratio is a value obtained by finally converting the number of emissions to the number of out balls for each section into%. This indicates that only two digits after the decimal point are required for the result of division.

Such "% conversion" points correspond to multiplying by the multiplicand "100". Therefore, it can be expressed by the formula of base ratio = number of payouts ÷ number of out balls x 100. However, when the number of payouts ≤ the number of out balls, the values are after the decimal point in the order of this formula, and for example, the main CPU 300a cannot calculate.

Therefore, the calculation order is changed, and the calculation is performed in the order of base ratio = number of payouts × 100 ÷ number of out balls (first, the number of payouts is multiplied by the multiplicand, and then divided by the number of out balls). By doing so, it is possible to complete the operation result only with an integer without performing the operation after the decimal point.

Further, in the present embodiment, the value after the decimal point when converted to% is rounded off. However, since the main CPU 300a cannot handle numbers after the decimal point and the calculation is performed in binary, the number of payouts × the number of multiplicands “100” and the number of out balls are doubled first to double the base ratio. Ask for. Then, if the least significant bit (corresponding to the value after the decimal point) of the value (binary number) twice the obtained base ratio is "1" (if the value after the decimal point is 0.5 or more), the obtained base After adding "1" to the value of twice the ratio, the value is halved (shifted by 1 bit to the right) to round up the decimal point, and the least significant bit (below the decimal point) of the value twice the obtained base ratio. If (corresponding to the value) is "0" (if the number after the decimal point is less than 0.5), the value that is twice the obtained base ratio is halved (shifted to the right) to reduce the number after the decimal point. truncate. As a result, the value after the decimal point can be rounded off.

Specifically, in the main CPU 300a, the division is replaced with a subtraction, and the integer number "691200", which is 2 x the number of payouts (3456) x 100, is doubled to the integer "10000", which is the number of out balls. Subtract the number multiplied by the predetermined integer "128 (2 x 2 to the 6th power)", and then change the integer to "64 (2 x 2 to the 5th power)" → "32 (2 x 2 to the 4th power)". → "16 (2 x 2 to the 3rd power)" → "8 (2 x 2 to the 2nd power)" → "4 (2 x 2 to the 1st power)" → "2 (2 x 2 to the 0th power)" → " Change in the order of "1 (2 x 2 to the -1st power)" (shift 1 bit to the right), multiply by the divisor, and subtract from the dividend. Here, the integer to be multiplied by the divisor starts from 2 × 64 because the display of the base ratio is in the range of 0 to 99, and when the base ratio is 100% or more, “99.” is displayed. This is because it is not necessary to subtract a numerical value of "2 x 128 (2 to the 7th power)" or more because of the specifications.

Specifically, as shown in FIG. 18, in the first calculation, the division is less than the divisor, so the process proceeds to the next step. Then, in the second calculation, since the divisor ≥ divisor, the divisor "64 (2 x 32) x 10000" is subtracted from the divisor "691200" to update the divisor to "51200" and the quotient "0" to "64". Is added to update the quotient to "64 (1000000B in binary)". In the third to fifth operations, the division is less than the divisor, so the process proceeds to the next step. In the sixth calculation, since the division ≥ divisor, subtract the divisor "4 (2 x 2) x 10000" from the division "51200" to update the division to "11200" and add "4" to the quotient "64". In addition, the quotient is updated to "68 (1000100B in binary)". In the 7th operation, the division is less than the divisor, so the process proceeds to the next step. In the 8th calculation, since the division ≥ divisor, the division "1 (2 x 0.5) x 10000" is subtracted from the division "11200" to update the division to "1200" and the quotient "68" to "1". Is added to update the quotient to "69 (1000101B in binary)".

After that, in the ninth calculation, the updated quotient "69 (1000101B in binary)" is divided by 2 (shifted by 1 bit to the right) to obtain the final base ratio. At this time, if the quotient is simply divided by 2, the quotient is "34.5". However, as described above, the main CPU 300a cannot handle the decimal point, so if the least significant bit of the quotient is "1B", the quotient is "1B". After shifting "69" to the right by 1 bit, add "1" to make the quotient "35 (0100011B in binary)".

According to such an operation example, division can be realized only by simple operations such as addition, subtraction, and multiplication, and by only integers. Further, here, since it is sufficient to repeat the calculation nine times, the calculation process can be performed quickly. In addition, the base ratio can be rounded to the nearest whole number.

Next, the main processing of the main control board 300 as the game progresses in the gaming machine 100 will be described with reference to a flowchart.

(CPU initialization process of main control board 300)
FIG. 19 is a flowchart illustrating the CPU initialization process (S100) in the main control board 300.

When power is supplied from the power supply board, a system reset occurs in the main CPU 300a, and the main CPU 300a performs the following CPU initialization process (S100).

(Step S100-1)
When the power is turned on, the main CPU 300a reads a boot program from the main ROM 300b as an initial setting process, and performs setting processes necessary for executing various processes.

(Step S100-3)
The main CPU 300a sets the wait processing time in the timer counter.

(Step S100-5)
The main CPU 300a determines whether or not the power supply cutoff warning signal is detected. The main control board 300 is provided with a power supply cutoff detection circuit, and when the power supply voltage becomes equal to or less than a predetermined value, a power supply cutoff warning signal is output from the power supply detection circuit. If the power off warning signal is detected, the process is moved to step S100-3, and if the power off warning signal is not detected, the process is moved to step S100-7.

(Step S100-7)
The main CPU 300a determines whether or not the wait time set in step S100-3 has elapsed. As a result, if it is determined that the wait time has elapsed, the process is transferred to step S100-9, and if it is determined that the wait time has not elapsed, the process is transferred to step S100-5.

(Step S100-9)
The main CPU 300a executes a process necessary for permitting access to the main RAM 300c.

(Step S100-11)
The main CPU 300a determines whether or not the backup valid flag indicating that the backup is valid is on. As a result, if it is determined that the backup valid flag is on, the process is transferred to step S100-13, and if it is determined that the backup valid flag is not on, the process is transferred to step S100-19.

(Step S100-13)
The main CPU 300a executes a process necessary for calculating a checksum of a used area (F000H to F1FFH) in the main RAM 300c.

(Step S100-15)
The main CPU 300a executes a process necessary for calculating a checksum of an unused area (F210H to F228H) in the main RAM 300c.

(Step S100-17)
The main CPU 300a determines whether the checksum calculated in step S100-13 and step S100-15 does not match the checksum saved when the power is turned off. As a result, if it is determined that the two do not match, the process is transferred to step S100-19, and if it is determined that the two do not match (match), the process is transferred to step S100-21.

(Step S100-19)
The main CPU 300a performs an initialization process for clearing an unused area of the main RAM 300c.

(Step S100-21)
The main CPU 300a determines whether or not the RAM clear flag is turned on. A RAM clear button (not shown) is provided on the back surface of the game board 108, and when the RAM clear button is pressed, the RAM clear detection switch detects the pressing operation of the RAM clear button and controls the main control. The RAM clear signal is output to the board 300. When the power is turned on while the RAM clear button is pressed, the RAM clear signal is input and the RAM clear flag is turned on. Then, when it is determined that the RAM clear flag is on, the process is transferred to step S100-23, and when it is determined that the RAM clear flag is not turned on, the process is transferred to step S100-29.

(Step S100-23)
The main CPU 300a performs an initialization process for clearing the used area of the main RAM 300c.

(Step S100-25)

(Step S100-27)
The main CPU 300a performs a transmission process (stores the command in the transmission buffer) of a payout command (RAM clear designation command) for transmitting to the payout control board 310 that the used area of the main RAM 300c has been cleared.

(Step S100-29)
The main CPU 300a performs a power restoration process related to power restoration in the main RAM 300c.

(Step S100-31)
The main CPU 300a performs a transmission process (stores the command in the transmission buffer) of a subcommand (power restoration designation command) for transmitting to the sub-control board 330 that the power has been restored from the power failure.

(Step S100-33)
The main CPU 300a performs a transmission process (stores the command in the transmission buffer) of a payout command (power return designation command) for transmitting to the payout control board 310 that the power has been restored from the power failure.

In this way, when clearing the RAM, the checksum is calculated first, and if the checksums do not match, the unused area is initialized first, and then the used area is initialized. On the other hand, if the checksums match, it is determined whether the RAM clear flag is on, and if the RAM clear flag is on, the used area is initialized.

As a result, when the RAM clear flag is turned on, it is not necessary to initialize the unused area. Therefore, when the RAM clear switch is operated, the data related to the base ratio (unused area) that is not desired to be initialized is initialized. You don't have to change it.

(Step S100-35)
The main CPU 300a includes a special symbol type designation command at power-on indicating the special symbol type, a special 1 hold designation command indicating the special 1 hold number (X1), and a special 2 hold designation command indicating the special 2 hold number (X2). Power-on subcommands for sending commands necessary for producing the initial state at power-on, such as the special symbol winning order command that indicates the stored special 1 hold and special 2 hold winning order, to the sub-control board 330. Executes set processing (commands are stored in the send buffer).

That is, when the hit symbol random number goes around from the initial value update random number for the hit symbol random number to the initial value update random number -1 for the hit symbol random number by the update process of the hit symbol random number described later, the hit symbol random number is obtained at that time. It will be updated to the initial value update random number for the winning symbol random number.

(Step S100-43)
The main CPU 300a analyzes the received data (main command) received from the payout control board 310 and executes various processes according to the received data.

(Step S100-45)
The main CPU 300a performs a process for transmitting a subcommand stored in the transmission buffer to the sub-control board 330.

(Step S100-47)
The main CPU 300a performs a process for permitting an interrupt.

(Step S100-49)
The main CPU 300a updates the reach group determination random number, the reach mode determination random number, and the variation pattern random number, and thereafter repeats the process from step S100-33. In the following, the reach group determination random number, the reach mode determination random number, and the variation pattern random number for determining the variation effect pattern are collectively referred to as a variation effect random number.

Next, interrupt processing on the main control board 300 will be described. Here, the save process (XINT interrupt process) and the timer interrupt process when the power is turned off will be described.

(Evacuation processing when the power of the main control board 300 is turned off (XINT interrupt processing))
FIG. 20 is a flowchart illustrating an evacuation process (XINT interrupt process) when the power is turned off in the main control board 300. The main CPU 300a monitors the power supply disconnection detection circuit, and when the power supply voltage falls below a predetermined value, it interrupts during the interrupt permission period of the CPU initialization process (between the processes of steps S100-41 and S100-33).

(Step S300-21)
The main CPU 300a checks the power off warning signal.

(Step S300-23)
The main CPU 300a determines whether or not the power supply cutoff warning signal is detected. As a result, if it is determined that the power off warning signal has been detected, the process is transferred to step S300-19, and if it is determined that the power off warning signal has not been detected, the process is transferred to step S300-25. ..

(Step S300-25)
The main CPU 300a subtracts 1 from the value of the loop counter set in step S300-19.

(Step S300-27)
The main CPU 300a determines whether the counter value of the loop counter is not 0. As a result, if it is determined that the counter value is not 0, the process proceeds to step S300-21, and if it is determined that the counter value is 0, the process proceeds to the CPU initialization process (step S100) described above.

When the power is actually cut off, the operation of the gaming machine 100 is stopped while looping steps S300-19 to S300-27.

(Timer interrupt processing of main control board 300)
