  Next, games 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 the low probability game state is used as the gaming state when proceeding with both of these games. Alternatively, the game progresses in any gaming state in which any gaming state in the high probability gaming state and any gaming state in the non-short-time gaming state or the short-time gaming state are combined.

  Although the details of each gaming state will be described later, the low probability gaming state is a gaming state in which the probability of acquiring a right to execute a major game in which the big prize opening 128 is opened is set low, and the high probability gaming state This is a gaming state in which the probability of acquiring the right to execute a big game is set high.

  The non-short game state is a game state in which the movable piece 122b is less likely to be in the open state and the game ball is less likely to enter the second start port 122. The short-time game state is more than the non-short game state. Also, the movable piece 122b is likely to be in an open state, and a game ball is likely to enter the second start port 122. Note that 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 this embodiment.

  When the player operates the operation handle 112 to fire a game ball in 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 game is given to the player. A lottery for determining whether or not to give a profit (hereinafter referred to as a “larger lottery”) is performed. In this big game lottery, when a big win is won, the big winning hole 128 is opened and a big ball game that allows a game ball to enter the big winning hole 128 is executed. The gaming state is set to one of the above gaming states. In the following, a lottery lottery method is described.

  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 (big hit decision random number, hit symbol random number, reach group decision random number, reach reach) related to the big role lottery Mode decision random numbers and fluctuation pattern random numbers) are acquired, and each random number value is stored in the special figure storage area of the main RAM 300c. Hereinafter, various random numbers stored in the special figure holding storage area after the game ball has entered the first start port 120 are collectively referred to as special one hold, and the game ball enters the second start port 122. The various random numbers stored in the special figure storage area are collectively called special 2 reservation.

  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. Each of the first special figure reservation storage area and the second special figure reservation storage area has four storage units (first to fourth storage units). When a game ball enters the first start port 120, the special 1 hold is stored in order from the first storage unit in the first special figure storage area, and when the game ball enters the second start port 122, the special ball is stored. 2 reservations are stored in order from the first storage unit of the second special figure storage area.

  For example, when a game ball enters the first start port 120, if no hold is stored in any of the first to fourth storage units in the first special figure storage area, the first storage unit Special 1 hold is stored. Also, for example, when a game ball enters the first start port 120 in a state where special 1 hold is stored in the first storage unit to the third storage unit, the special 1 hold is stored in the fourth storage unit. Remember. In addition, even when a game ball enters the second start port 122, the special 2 reservation is stored in the first storage unit to the fourth storage unit of the second special figure storage area as described above. No special 2 reservation is stored in the storage unit with the smallest number (ordinal number).

  However, the number of special 1 reservations (X1) and the number of special 2 reservations (X2) that can be stored in the first special figure reservation storage area and the second special figure reservation storage area are each set to four. Therefore, for example, when a game ball enters the first start opening 120, if four special 1 reservations are already stored in the first special figure storage area, Special 1 hold is not newly stored by entering a game ball. Similarly, when a game ball enters the second start port 122 and four special 2 holds are already stored in the second special figure storage area, a game to the second start port 122 is stored. The special 2 hold is not newly memorized when the ball enters.

  FIG. 6 is a diagram illustrating a jackpot determination random number determination table. When a game ball enters the first start port 120 or the second start port 122, one big hit determination random number is acquired from the range of 0 to 65535. Then, when the big game lottery is started, that is, the jackpot determination random number determination table is selected according to the gaming state when the jackpot determination is performed, and the selected jackpot determination random number determination table and the acquired jackpot determination random number A lottery drawing is held.

  In the low-probability gaming state, when starting the big role lottery for special 1 hold and special 2 hold, as shown in FIG. According to the low probability jackpot determined random number determination table, when the jackpot determined random number is 10001 to 10164, it is determined to be a jackpot, and when it is any other jackpot determined random number, it is determined to be lost. Therefore, the jackpot probability in this case is about 1 / 399.6.

  Also, in the high-probability gaming state, when starting the big lottery for special 1 hold and special 2 hold, as shown in FIG. According to the high-accuracy jackpot determination random number determination table, if the jackpot determination random number is 10001-1640, it is determined to be a jackpot, and if it is any other jackpot determination random number, it is determined to be lost. Therefore, the jackpot probability in this case is about 1 / 39.96. Thus, in the case of a high probability gaming state, the jackpot probability is 10 times that in the case of a low probability gaming state. Note that the jackpot determination random number (10001 to 10164) that becomes “big hit” in the low probability gaming state becomes “big hit” even in the high probability gaming state.

  FIG. 7 is a diagram for explaining the winning symbol random number determination table. When a game ball enters the first start port 120 or the second start port 122, one winning design random number is acquired from the range of 0-99. Then, when the determination result of “big hit” is derived by the above-mentioned big game lottery, the type of special symbol is determined by the acquired winning symbol random number and the winning symbol random number determination table. At this time, if “big hit” is won by special 1 hold, as shown in FIG. 7A, the special random number judgment table for special 1 is selected, and “big win” is won by special 2 hold. For example, as shown in FIG. 7B, the special random number design random number determination table is selected. Below, the special symbol determined by the winning symbol random number, that is, the special symbol determined when the jackpot determination result is obtained is called the jackpot symbol, and the special symbol determined when the loss determination result is obtained. The design is called a lost design.

  According to the special symbol random number determination table for special 1 shown in FIG. 7 (a) and the special random number determination table for special 2 shown in FIG. 7 (b), depending on the value of the acquired random symbol random number, As described above, the type of special symbol (big hit symbol) is determined. In addition, when the lottery result is “losing” and the lottery result is derived by special 1 hold, the special symbol X is determined as the lost symbol without performing the lottery, and the lottery result is the special 2 When derived by holding, the special symbol Y is determined as a lost symbol without performing a lottery. In other words, the winning symbol random number determination table is referred to only when the big drawing lottery result is “big win”, and is not referred to when the big drawing lottery result is “lost”.

  FIG. 8 is a diagram for explaining 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 hold number, and the change state set in association with the game state. When a game ball enters the first start port 120 or the second start port 122, one reach group determination random number is acquired from the range of 0-10006. As described above, when the big drawing lottery result is derived, a process for determining a variation effect pattern for notifying the big drawing lottery result is performed. In the present embodiment, if the lottery result is “losing”, the group type is first determined by the reach group determination random number and the reach group determination random number determination table when determining the variation effect pattern.

  For example, when the gaming state is set to the non-temporary gaming state and the variation state is normally set to 1 variation state, when the lottery result of “losing” is derived based on the special 1 hold, If the special 1 holding number (hereinafter, simply referred to as “holding number”) when performing the lottery lottery is 0, the reach group determination random number determination table 1 is selected as shown in FIG. Similarly, if the number of holds is 1, the reach group determination random number determination table 2 is selected as shown in FIG. 8B, and if the number of holds is 2 or 3, the table shown in FIG. As shown, the reach group determination random number determination table 3 is selected. In FIG. 8, a 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.

  Thus, in this embodiment, the table for determining the variation effect pattern is determined based on the variation state in addition to the set game state. That is, the change state is defined as which table is used to determine the change effect pattern, and is a concept set separately from the game state.

  In addition, when the lottery lottery result is “big hit”, the group type is not determined in determining the variation effect pattern. That is, the reach group determination random number determination table is referred to only when the big drawing lottery result is “losing”, and is not referred to when the big drawing lottery result is “big hit”.

  FIG. 9 is a diagram for explaining a reach mode determination random number determination table. This reach mode determination random number determination table is a lost mode reach mode determination random number determination table that is selected when the lottery lottery result is “losing”, and a jackpot that is selected when the lottery lottery result is “big hit” The time reach mode decision random number judgment table is roughly divided. The lose time reach mode determination random number determination table is provided for each group type determined as described above, and the big hit time reach mode determination random number determination table is provided for each gaming state and symbol type. Each reach mode determination random number determination table may be provided for each hold type. Here, FIG. 9A shows an example of the lose mode reach mode determination random number determination table for group x referred to in a predetermined game state and symbol type, and FIG. 9A shows an example of the big hit time reach mode determination random number determination table. Shown in b).

  When a game ball enters the first start port 120 or the second start port 122, one reach mode determination random number is acquired from the range of 0 to 250. If the result of the lottery lottery is “losing”, as shown in FIG. 9A, the lost reach mode random number corresponding to the group type determined by the group type lottery is shown. The determination table is selected, and the variation mode number is determined based on the selected lose time reach mode determination random number determination table and the reach mode determination random number. Also, if the result of the big game lottery is “big hit”, as shown in FIG. 9B, the big hit hour reach mode determination random number determination table corresponding to the read gaming state and symbol type Is selected, and the variation mode number is determined based on the selected jackpot hour reach mode determination random number determination table and the reach mode determination random number.

  In each reach mode determination random number determination table, the reach mode determination random number is associated with a change pattern random number determination table, which will be described later, together with the change mode number, and at the same time the change mode number is determined, the change pattern A random number determination 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. In the present embodiment, the variation mode number and the variation pattern number described later are set in hexadecimal. In the following description, “H” is added to indicate a hexadecimal number, but “H” in FIGS. 9 to 11 indicates an arbitrary value indicated by a hexadecimal number.

  As described above, when the lottery lottery result is “losing”, 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 based on the lost time 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 gaming state.

  On the other hand, if the lottery lottery result is “big hit”, the big hit time reach mode determination random number determination table shown in FIG. 9 according to the decided big hit symbol (special symbol type), the gaming state at the time of the big win, etc. And the reach mode determination random number, the change mode number and change pattern random number determination table is determined.

  FIG. 10 is a diagram for explaining the variation pattern random number determination table. Here, a variation pattern random number determination table x of a predetermined table number x is shown, but many other variation pattern random number determination tables are provided for each table number.

  When a game ball enters the first start port 120 or the second start port 122, one variation pattern random number is acquired from the range of 0 to 238. Based on the variation pattern random number determination table determined simultaneously with the variation mode number and the obtained variation pattern random number, the variation pattern number is determined as illustrated.

  As described above, when the big character lottery is performed, the variation mode number and the variation pattern number are determined according to the result of the big character lottery, the determined symbol type, the gaming state, the number of holds, the hold type, and the like. These variation mode number and variation pattern number specify the variation effect pattern, and the variation effect mode and time are associated with each of them. Hereinafter, the variation mode number and the variation pattern number may be collectively referred to as variation information.

  FIG. 11 is a diagram for explaining the variation 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. According to this variation time 1 determination table, 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.

  As described above, when the variation pattern number is determined, the variation time 2 is determined according to the variation time 2 determination table shown in FIG. According to the variation time 2 determination table, the variation time 2 is associated with each variation pattern number, and the corresponding variation time 2 is determined according to the determined variation pattern number. The total time of the variation times 1 and 2 determined in this way becomes the variation production time for notifying the lottery result, that is, the variation time.

  When the variation mode number is determined as described above, a 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 A 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 of the variation effect is mainly determined based on the received variation mode command, and the second half of the variation effect is mainly determined based on the received variation pattern command. It becomes. Hereinafter, the variation mode command and the variation pattern command may be collectively referred to as a variation command, and details thereof will be described later.

  FIG. 12 is a diagram for explaining the special electric accessory operating ram set table. The special electric accessory actuated ram set table stores various data for controlling the major actor game. During the major actor game, the special electric accessory actuated ram set table is referred to, The solenoid 128c is energized and controlled. Actually, a plurality of special electric accessory actuating ram set tables are provided for each jackpot symbol type, and the corresponding table is set at the start of the big bonus game according to the determined jackpot symbol type. Here, for convenience of explanation, control data for all jackpot symbols is shown in one table.

  When the special symbols A to D, which are jackpot symbols, are determined, as shown in FIG. 12, a big game is executed with reference to the special electric accessory operating ram set table. The big game is composed of a plurality of round games in which the grand prize winning opening 128 is opened and closed a predetermined number of times. According to this special electric accessory actuated ram set table, the opening time (waiting time until the first round game is started), the special electric accessory maximum actuating number (round game executed during one major game) The number of times of opening / closing switching of the special electric accessory (number of times of opening of the large winning opening 128 during one round), solenoid energization time (energization time of the large winning opening solenoid 128c for each opening of the large winning opening 128, ie, 1 Number of times of winning the winning prize opening 128), the prescribed number (the maximum number of winnings possible to the winning prize opening 128 in one round game), the closing time of the winning prize opening (the closing time of the winning prize opening 128 between round games) In other words, interval time), ending time (from the end of the last round game until normal special game (variable display of special symbols described later) is resumed) Waiting time), as control data for major role game, for each type of bonus game symbol, it is stored in advance as shown.

  FIG. 13 is a diagram illustrating a game state setting table for setting the game state after the end of the big game. As shown in FIG. 13, when the special symbol A is determined, the low probability gaming state is set after the end of the big game, and when the special symbols B to D are determined, the high probability is set after the end of the main character game. In addition to being set to the gaming state, the number of continuations of the high probability gaming state (hereinafter referred to as “high probability number”) is set to 10,000 times. This means that the high-probability gaming state continues until the big-game lottery result is determined 10,000 times. However, the above-mentioned high-accuracy count indicates the maximum number of continuations in the high probability gaming state of 1. If the jackpot is won before reaching the above continuation count, the gaming state is set again. Will be done. Accordingly, when the high probability gaming state is set after the end of the big game, if the lottery lottery result is derived 10,000 times without deriving the jackpot lottery result in the high probability gaming state, the low probability game The gaming state will be changed to the state.

  In addition, when the special symbol A is determined, it is set to the non-time-saving gaming state after the end of the big game, and when the special symbols B to D are determined, the time-saving gaming state is set after the end of the main character game. In addition, the number of continuations of the short-time gaming state (hereinafter referred to as “short-time number of times”) is set to 10,000. This means that the short-time gaming state continues until the big game lottery result is determined 10,000 times. However, the above short time count indicates the maximum number of continuations in the short time gaming state of 1, and if the big win is won before reaching the above continuation number of times, the gaming state is set again. It will be.

  In this case, the game state, the number of high-accuracy times, and the number of time reductions are set according to the type of jackpot symbol, but depending on both the type of jackpot symbol and the game state at the time of winning the jackpot symbol, You may set the game state and the number of high-accuracy times and time savings after the end of.

  FIG. 14 is a diagram for explaining the hit determination random number determination table. When a game ball flowing down the game area 116 passes through the gate 124, a normal symbol determination process (hereinafter referred to as “normal drawing lottery”) associated with whether or not to energize the movable piece 122b of the second start port 122 is controlled. ) Is performed.

  As will be described in detail later, when the game ball passes through the gate 124, one hit-determined random number is acquired from the range of 0 to 99, and four random number values are stored in the general-purpose reserved storage area of the main RAM 300c. Is stored as the upper limit. That is, the usual-pending storage area includes four storage units that save the winning random numbers. Accordingly, when a game ball passes through the gate 124 in a state in which the hit random numbers are stored in all the four storage units of the usual reserved storage area, the hit random numbers are stored based on the passage of the game balls. There is nothing. Hereinafter, the winning random number stored in the usual figure storage area after the game ball passes through the gate 124 is referred to as the usual figure holding.

  When the general drawing lottery is started in the non-short game state, as shown in FIG. 14 (a), the random number determination table for non-time game state is determined. According to the per-determined random number determination table for the non-short-time gaming state, when the hit determined random number is 0, the hit symbol is determined as the normal symbol type, and when the hit determined random number is 1 to 99, The lost symbol is determined as the normal symbol type. Therefore, the probability that the winning symbol is determined in the non-short 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 the open state, and when the lost symbol is determined, the second starting port 122 is determined. The movable piece 122b is maintained in the closed state.

  In addition, when the regular drawing lottery is started in the short-time gaming state, as shown in FIG. 14 (b), the per-decision random number determination table for the short-time gaming state is referred to. According to the per-determined random number determination table for the short game state at this time, when the winning determined random number is 0 to 98, the winning symbol is determined as the normal symbol type, and when the winning determined random number is 99, A lost symbol is determined as the symbol type. Therefore, the probability that the winning symbol is determined in the short-time gaming state, that is, the winning probability is 99/100.

  FIG. 15A is a diagram for explaining a normal symbol variation time data table, and FIG. 15B is a diagram for explaining an opening / closing control pattern table. As described above, when the regular drawing lottery is performed, the variation time of the normal symbol is determined. The normal symbol variation time data table is referred to when determining the variation time of the normal symbol when the winning symbol or the lost symbol is determined by the general symbol lottery. According to this normal symbol variation time data table, when the gaming state is set to the non-short-time gaming state, the variation time is determined to be 10 seconds, and when the gaming state is set to the short-time gaming state, the variation Time is determined to be 1 second. When the variation time is determined in this way, the normal symbol display 168 is varied and displayed (flashing display) over the determined time. 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.

  When the winning symbol is determined by the regular symbol lottery and the normal symbol indicator 168 is lit, the movable piece 122b of the second start port 122 is opened and closed as shown in FIG. 15B. The energization is controlled with reference to the table. Actually, the opening / closing control pattern table is provided for each gaming state, and the corresponding table is set at the start of energization of the ordinary electric accessory solenoid 122c according to the gaming state when the ordinary 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 second start port 122 is controlled to open and close with reference to the opening and closing control pattern table. According to this open / close control pattern table, the time before the opening of the normal electric power (the waiting time until the opening of the second start port 122 is started), the maximum number of switching times of the normal electric accessory (the number of times of opening the second start port 122) , Solenoid energization time (the energization time of the ordinary electric accessory solenoid 122c every time the second start port 122 is opened, that is, one open time of the second start port 122), the specified number (the total of the second start port 122) The maximum possible number of winnings at the second start port 122 during opening), the ordinary power closing time (the closing time between each opening of the second starting port 122, that is, the rest time), the normal power effective state time (second starting) The waiting time from the end of the last opening of the mouth 122), the waiting time for the end of ordinary power transmission (the waiting time until the normal symbol variation display to be described later is resumed after elapse of the ordinary power transmission valid time) 122 control data To, for each gaming state, is stored in advance as shown.

  As described above, the non-time-saving gaming state and the time-saving gaming state are associated with the opening / closing control conditions for opening and closing the second start port 122 as the game progress conditions. It becomes easier for a game ball to enter the second starting port 122 than in the gaming state. In other words, in the short-time gaming state, as long as the game ball passes through the gate 124, the lottery is drawn one after another, and the second start port 122 is frequently opened, so that the player can use the game ball. It becomes possible to perform a lottery lottery while reducing.

  The opening / closing condition of the second start port 122 defines three elements: the normal symbol winning probability, the normal symbol variation display time, and the second start port 122 opening time. And in this embodiment, by setting the time-saving gaming state more advantageously than the non-time saving gaming state in two of these three elements, the time-saving gaming state is more advantageous than the non-time saving gaming state. The game ball is set to be easy to enter the second start port 122. However, among the above three elements, one or three elements may be set more advantageously in the short-time gaming state than in the non-short-time gaming state. In any case, the short-time gaming state is advantageous for at least one element compared to the non-short-time gaming state, so that the time-short gaming state is comprehensively more advantageous than the non-time-short gaming state. What is necessary is just to make a game ball enter into 122 easily. That is, when the gaming state is set to the non-short-time 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 short-time gaming state, It is sufficient that the movable piece 122b is controlled to open and close according to the second condition that tends to be in the open state.

  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 for explaining a display mode of the base display 304. In the main control board 300, the base ratio when the gaming state is 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 (the number of out balls is 60000), and the general winning port 118, the first start port 120 and the first start port 120 with respect to the number of out balls. 2 The total number (the number of payouts) of prize balls to be paid out when a game ball enters the start port 122 is shown as a percentage (%).

  As shown in FIG. 16, the base indicator 304 displays the base ratio of the current section and the base ratio of the previous section by switching at preset intervals (for example, 5 seconds).

  The base display 304 displays an identifier “bc” or “bb” for identifying whether the base segment is the base ratio of the current section or the base ratio of the previous section among the seven segments 304a and 304b. The base indicator 304 displays the base ratio corresponding to the identifier “bc” or “bb” with two digits in the seven segments 304c and 304d.

  Therefore, if the base ratio of the current section is 30%, when displaying the base ratio of the current section, “bc” is displayed in the 7 segments 304a and 304b, and “30” is displayed in the 7 segments 304c and 304d. Is displayed. If the base ratio of the previous section is 38%, when displaying the base ratio of the previous section, “bb” is displayed in the 7 segments 304a and 304b, and “38” is displayed in the 7 segments 304c and 304d. Is displayed.

  FIG. 17 is a diagram for explaining a section of the base ratio displayed on the base display 304. Here, during the period from the time when the gaming machine 100 is manufactured to the time when it is installed in the hall and the player plays a game, inspection at the time of manufacture, trial operation (operation check) in the hall, and the like are performed. Game balls are also emitted and discharged during such manufacturing inspections and test runs in the hall, but if the number of out balls and the number of discharges are counted during this time, the game is played by the player. There is a risk that the base ratio cannot be accurately derived during the operation.

  Therefore, as shown in FIG. 17 (a), the first section (out-of-target section) in which the total number of out balls detected by the out ball detection switch 129s is 0 to 300, The base ratio is excluded from the target to be derived as an out-ball detected before the player plays a game such as a trial run. Similarly, the number of payouts that are 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 displayed blinking, and the base ratio is lit up as “-”. To do. Since the previous section does not exist, when the base ratio of the previous section is displayed, the identifier “bb” is displayed blinking and the base ratio is displayed as “−−”.

  When the number of out balls is 301 to 60300 as the first section, the base ratio is derived at any time (in real time) in the first section, and when the base ratio of the current section is displayed, the identifier “bc ”And the derived base ratio are lit. At this time, when the number of out balls is between 301 and 6299 (the number of out balls in the section is 5999 or less), the identifier “bc” is displayed in a blinking manner to derive the base ratio of the current section. Notify that there are few samples 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), the identifier “bc” is lit to display many samples when deriving the base ratio of the current section. Informing that the base ratio is stable.

  In addition, since the previous section does not exist in the first section, when the base ratio of the previous section is displayed, the identifier “bb” is displayed in a blinking manner and the base ratio is lit up as “-”. To do.

  Also, in the second section where the number of out balls is 60301 to 120300, as in the first section, the base ratio is derived as needed (in real time), and when the base ratio of the current section is displayed, The identifier “bc” is lit or blinked according to the number of balls, and the derived base ratio is displayed. In the second section, when the base ratio of the previous section is displayed, the identifier “bb” is lit 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 for every 60000 balls (out of the n-th section) excluding the first 300 out balls. The final base ratio of the section is displayed as the base ratio of the previous section.

  As a result, it is possible to exclude the number of out balls and the number of discharged balls before the game is performed by the player, such as inspection at the time of manufacturing and trial operation (operation check) in the hall, from the base ratio derived target. The ratio can be accurately derived.

  Note that when the base ratio is derived, the base ratio may temporarily exceed 100%. For example, when the first ball in the section enters the first start port 120, the number of out balls is 1, whereas the number of payouts is a prize ball obtained by entering the first start port 120. The base ratio is 300%. In such a case, the base indicator 304 can display the base ratio only in two digits, so that “99.” is lit to notify that the base ratio exceeds 100%.

  FIG. 18 is a diagram for explaining a base ratio calculation method. In FIG. 18, the base ratio is derived on the assumption 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 discharges with respect to the number of out balls for each section into%. This indicates that only two digits after the decimal point are necessary for the result of division.

  This “% conversion” point corresponds to multiplication by the multiplicand “100”. Therefore, it can be expressed by the following formula: base ratio = number of payouts / number of out balls × 100. However, when the number of payouts is equal to or less than the number of outballs, the value in the order of this expression is a value after the decimal point, and for example, the main CPU 300a cannot perform the calculation.

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

  Moreover, in this embodiment, the value below the decimal point when converted into% is rounded off. However, since the main CPU 300a cannot handle numbers after the decimal point and is operated in binary numbers, the number of payouts × multiplicand “100” and the number of out-balls are doubled first to double the base ratio. Ask for. If the least significant bit (equivalent to the value after the decimal point) of the value twice the base ratio (binary number) is “1” (if the decimal point is 0.5 or more), then the calculated base After adding "1" to the value twice the ratio, the value after the decimal point is rounded up by halving the value (shifting 1 bit to the right), and the least significant bit (below the decimal point) If the value is “0” (if the fractional part is less than 0.5), then double the calculated base ratio to the half value (shifted to the right) as it is. 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 subtraction, and the power of 2 is doubled from the dividend “691200” that is 2 × the number of payouts (3456) × 100 to the divisor “10000” that is the number of out balls. The number obtained by multiplying the predetermined integer “128 (2 × 2 to the sixth power)” is subtracted, and then the integer is “64 (2 × 2 to the fifth power)” → “32 (2 × 2 to the fourth power)”. → “16 (2 × 2 to the third power)” → “8 (2 × 2 to the second power)” → “4 (2 × 2 to the first power)” → “2 (2 × 2 to the zero power)” → “ 1 (2 × 2 to the power of −1) ”(shifted 1 bit to the right), multiplied by the divisor, and subtracted from the dividend. Here, the integer to be multiplied by the divisor starts from 2 × 64 when the base ratio is in the range of 0 to 99, and “99.” is displayed when the base ratio is 100% or more. This is because it is not necessary to subtract a numerical value of “2 × 128 (2 to the 7th power)” or more because of the specification.

  Specifically, as shown in FIG. 18, in the first calculation, since dividend is less than divisor, the process proceeds to the next. Then, in the second calculation, since the dividend is greater than or equal to the divisor, the dividend “64 (2 × 32) × 10000” is subtracted from the dividend “691200” to update the dividend to “51200” and the quotient “0” is “64”. ”And the quotient is updated to“ 64 (1000000B in binary number) ”. In the third to fifth calculations, since dividend is less than divisor, the process proceeds. In the sixth calculation, since the dividend is greater than or equal to the divisor, the dividend “4 (2 × 2) × 10000” is subtracted from the dividend “51200” to update the dividend to “11200”, and “4” is added to the quotient “64”. In addition, the quotient is updated to “68 (1000100B in binary number)”. Since the dividend is less than the divisor in the seventh calculation, the process proceeds. In the eighth calculation, since the dividend is not less than the divisor, the dividend “1 (2 × 0.5) × 10000” is subtracted from the dividend “11200” to update the dividend to “1200” and the quotient “68” is “1”. "And the quotient is updated to" 69 (1000101B in binary number) ".

  Thereafter, in the ninth calculation, the updated quotient “69 (1000101B in binary number)” is divided by 2 (shifted to the right by 1 bit) to obtain the final base ratio. At this time, if the value is simply divided by 2, the quotient is “34.5”. However, as described above, the main CPU 300a cannot handle the fractional part, so if the least significant bit of the quotient is “1B”, After shifting “69” to the right by 1 bit, “1” is added to make the quotient “35 (01000111B in binary number)”.

  With this calculation example, division can be realized by only simple calculations such as addition, subtraction, and multiplication, and only by an integer. Here, it is sufficient to repeat the calculation nine times, so that the calculation process can be performed quickly. In addition, the base ratio can be rounded off.

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

(CPU initialization processing of main control board 300)
FIG. 19 is a flowchart for explaining 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)
The main CPU 300a reads a startup program from the main ROM 300b as an initial setting process in response to power-on, and performs a setting process necessary for executing various processes.

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

(Step S100-5)
The main CPU 300a determines whether a power-off notice signal is detected. The main control board 300 is provided with a power-off detection circuit, and when the power supply voltage becomes a predetermined value or less, a power-off notice signal is output from the power supply detection circuit. If the power-off notice signal is detected, the process proceeds to step S100-3. If the power-off notice signal is not detected, the process proceeds 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 proceeds to step S100-9. If it is determined that the wait time has not elapsed, the process proceeds to step S100-5.

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

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

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

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

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

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

(Step S100-21)
The main CPU 300a determines whether or not the RAM clear flag is on. A RAM clear button (not shown) is provided on the back 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 the main control is performed. A RAM clear signal is output to the substrate 300. When the power is turned on while the RAM clear button is pressed, a RAM clear signal is input and the RAM clear flag is turned on. If it is determined that the RAM clear flag is on, the process proceeds to step S100-23, and if it is determined that the RAM clear flag is not on, the process proceeds to step S100-29.

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

(Step S100-25)
The main CPU 300a performs a transmission process (stores the command in a transmission buffer) of a subcommand (RAM clear designation command) for transmitting to the sub control board 330 that the use area of the main RAM 300c has been cleared.

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

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

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

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

  Thus, when the RAM is cleared, the checksum is calculated first. If the checksums do not match, the non-use area is initialized first, and then the use area is initialized. On the other hand, if the checksums match, it is determined whether the RAM clear flag is on. If the RAM clear flag is on, the use area is initialized.

  As a result, when the RAM clear flag is on, it is not necessary to initialize the non-use area, so that the data related to the base ratio (non-use area) that is not to be initialized when the RAM clear switch is operated is initialized. It does n’t matter.

(Step S100-35)
The main CPU 300a includes a special symbol type designation command at power-on indicating a special symbol type, a special 1 hold designation command indicating a special 1 hold number (X1), a special 2 hold designation command indicating a special 2 hold number (X2), Power-on subcommand for transmitting to the sub-control board 330 a command required to produce an initial state when the power is turned on, such as a special symbol winning order command indicating the stored special order 1 and special 2 winning orders. Executes the set process (stores the command in the transmission buffer).

(Step S100-39)
The main CPU 300a performs processing for prohibiting interruption.

(Step S100-41)

The initial value update random number for the winning symbol random number is for determining an initial value and an end value of the winning symbol random number. That is, when the winning symbol random number is rounded from the initial value updating random number for the winning symbol random number to the initial value updating random number -1 for the winning symbol random number by the update process of the winning symbol random number described later, It will be updated to the initial value update random number for winning design random numbers.

(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 300 a performs processing for transmitting the subcommand stored in the transmission buffer to the sub-control board 330.

(Step S100-47)
The main CPU 300a performs processing 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 processing from step S100-33. Hereinafter, 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 in the main control board 300 will be described. Here, the power-off saving process (XINT interrupt process) and the timer interrupt process will be described.

(Evacuation processing when the main control board 300 is powered off (XINT interrupt processing))
FIG. 20 is a flowchart for explaining the power-off saving process (XINT interrupt process) in the main control board 300. The main CPU 300a monitors the power-off detection circuit.

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

(Step S300-23)
The main CPU 300a determines whether a power-off notice signal is detected. As a result, if it is determined that the power-off notice signal is detected, the process proceeds to step S300-19. If it is determined that the power-off notice signal is not detected, the process proceeds 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 zero. 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).

  Note that when the power is actually cut off, the operation of the gaming machine 100 is stopped while the steps S300-19 to S300-27 are looped.

(Timer interrupt processing of main control board 300)
FIG. 21 is a flowchart for explaining timer interrupt processing in the main control board 300. The main control board 300 is provided with a reset clock pulse generation circuit that generates a clock pulse every predetermined cycle (in this embodiment, 4 milliseconds, hereinafter referred to as “4 ms”). When a clock pulse is generated by the reset clock pulse generation circuit, the CPU initialization process (step S100) is interrupted, and the following timer interrupt process is executed.

When the random number is a fixed value, a prefetch designation variation mode command and a prefetch designation variation pattern command are transmitted to the sub-control board 330 as a prefetch designation command. On the other hand, if the stored hold is a hold that is lost, and the reach group determination random number is an indefinite value, an indefinite value command is transmitted to the sub-control board 330 as a prefetch designation command. Each of the prefetch designation commands described above is configured such that a command for a low probability gaming state and a command for a high probability gaming state can be distinguished from each other.
