  Hereinafter, a pachi-slot showing an embodiment of a gaming machine according to the present invention will be described with reference to the drawings.

<Function flow>
First, the functional flow of the pachislot will be described with reference to FIG. In the pachislot machine of this embodiment, medals are used as game media for playing games. In addition to medals, for example, coins, game balls, game point data, tokens, or the like can be applied as game media.

  When a player inserts a medal into the pachislot and operates the start lever, one value (hereinafter, random number value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal lottery means performs lottery based on the extracted random number value and determines an internal winning combination. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations are those related to “winning” that gives the player benefits such as medal payout, re-game operation, bonus game operation, etc., and other so-called “losing” And are provided.

  Further, when the start lever is operated, a plurality of reels are rotated. After that, when the player presses the stop button corresponding to the predetermined reel, the reel stop control means and the special game stop control means, based on the internal winning combination and the timing when the stop button is pressed, Control to stop rotation.

  In the pachislot, basically, a control for stopping the rotation of the corresponding reel is performed within a specified time (190 msec or 75 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding pieces”, and when the specified period is 190 msec (first maximum delay time), the maximum When the number (first maximum number of sliding symbols) is set to 4 symbols and the specified period is 75 msec (second maximum delay time), the maximum number (second maximum number of sliding symbols) is determined as the symbol. Set to one.

  When the internal winning combination allowing the symbol combination display related to winning is determined, the reel stop control means usually displays the symbol combination within the specified time of 190 msec (four symbols) for the winning determination line. The rotation of the reel is stopped so as to display as much as possible. Further, the reel stop control means is, for example, 1 at the time of operation of “MB” (middle bonus) that continuously activates the challenge bonus (hereinafter referred to as “CB”) and “CB”, which are the second type special feature. For one or more reels, the rotation of the reels is stopped so that the combination of symbols is displayed as much as possible along the winning determination line within a prescribed time of 75 msec (one frame of symbols). In the present embodiment, an example will be described in which the reel for reducing the maximum number of sliding pieces during the MB (CB) operation is a left reel 3L (see FIG. 2) described later. Furthermore, the reel stop control means uses various specified times corresponding to the gaming state to rotate the reels so that combinations of symbols that are not permitted to be displayed by the internal winning combination are not displayed along the winning determination line. Stop.

  Thus, when the rotation of the plurality of reels is all stopped, the winning determination means determines whether or not the combination of symbols displayed along the winning determination line is related to winning. When the winning determination means determines that the symbol combination is related to winning, a bonus such as a medal payout is given to the player. In the pachislot, the above-described series of flow operations are performed as a single game.

  Also, in the pachislot, in the series of operations described above, there are various effects using video display performed by a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, or a combination thereof. Done.

  When the start lever is operated, an effect random number value (hereinafter referred to as effect random number value) is extracted separately from the random number value used for determining the internal winning combination. When the effect random number is extracted, the effect content determining means determines the effect content to be executed this time from among a plurality of types of effect contents associated with the internal winning combination.

  When the contents of the effect are determined, the effect executing means executes the corresponding effect in conjunction with each opportunity, such as when the rotation of the reels starts, when the rotation of each reel stops, or when determining whether there is a winning. In this way, in the pachislot machine, the player has the opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. It is possible to improve the player's interest.

  As shown in FIG. 4, the pachi-slot 1 includes a main control circuit 41, a sub-control circuit 42, and peripheral devices (actuators) electrically connected to these circuits.

[Main control circuit]
The main control circuit 41 is mainly configured by a microcomputer 50 installed on a circuit board (main board 31). As other components, the main control circuit 41 includes, as shown in FIG. , And a payout completion signal circuit 66.

  The microcomputer 50 includes a main CPU 51 (special game control means, normal game control means), a main ROM (Read Only Memory) 52, and a main RAM (Random Access Memory) 53.

  The main ROM 52 stores various control programs for various processes (see FIGS. 31 to 46 described later) executed by the main CPU 51, data tables such as an internal lottery table (see FIGS. 6 to 24), and the sub control circuit 42. Data and the like for transmitting a control command (command) are stored. The main RAM 53 is provided with a storage area (see FIGS. 25 to 30) for storing various data such as an internal winning combination determined by execution of the control program.

  As shown in FIG. 4, a clock pulse generation circuit 54, a frequency divider 55, a random number generator 56 and a sampling circuit 57 are connected to the main CPU 51. The clock pulse generation circuit 54 and the frequency divider 55 generate clock pulses. The main CPU 51 executes a control program based on the generated clock pulse. The random number generator 56 generates a random number in a predetermined range (for example, 0 to 65535). Then, the sampling circuit 57 extracts one value from the generated random numbers.

  Various switches and sensors are connected to the input port of the microcomputer 50. The main CPU 51 receives input signals from various switches and controls the operation of peripheral devices such as stepping motors 61L, 61C, 61R.

  The stop switch 17S (stop operation detecting means) detects that the player has pressed each of the left stop button 17L, the middle stop button 17C, and the right stop button 17R (stop operation). The start switch 16S (start operation detecting means) detects that the start lever 16 has been operated by the player (start operation). The settlement switch 14S detects that the settlement button 14 has been pressed by the player.

  The medal sensor 35S (insertion operation detecting means) detects that a medal inserted into the medal insertion slot 11 has passed through the selector 35. The bet switch 12S detects that the bet button 12 has been pressed by the player.

  Peripheral devices whose operations are controlled by the microcomputer 50 include three stepping motors 61L, 61C, 61R (variation display means), a 7-segment display 6, and a hopper 33. A drive circuit for controlling the operation of each peripheral device is connected to the output port of the microcomputer 50.

  The motor drive circuit 62 controls the drive of the three stepping motors 61L, 61C, 61R provided corresponding to the left reel 3L, the middle reel 3C, and the right reel 3R, respectively. The reel position detection circuit 63 detects, for each reel, a reel index indicating that the reel has made one rotation by an optical sensor having a light emitting unit and a light receiving unit.

  Each of the three stepping motors 61L, 61C, 61R has a configuration in which the momentum is proportional to the number of output pulses, and the rotation axis can be stopped at a specified angle. The driving force of each stepping motor is transmitted to the corresponding reel via a gear having a predetermined reduction ratio. Each time one pulse is output to each stepping motor, the corresponding reel rotates at a constant angle.

  The main CPU 51 detects the reel index of each reel and then counts the number of times a pulse is output to the corresponding stepping motor, thereby determining the rotation angle of each reel (specifically, how many reels the number of symbols is). Only managed).

  Here, the management of the rotation angle of each reel will be specifically described. The number of pulses output to each stepping motor is counted by a pulse counter (not shown) provided in the main RAM 53. Each time the output of a predetermined number of pulses (for example, 16 times) necessary for the rotation of one symbol is counted by the pulse counter, the value of the symbol counter (not shown) provided in the main RAM 53 is set to “1”. "Is added. A symbol counter is provided for each reel. The value of the symbol counter is cleared when the reel index is detected by the reel position detection circuit 63.

  In other words, in the present embodiment, by managing the value of the symbol counter, it is managed how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol on each reel is detected with reference to the position where the reel index is detected.

  In the present embodiment, as described above, the maximum number of sliding symbols during normal game (when MB is not operating) is set to four symbols, and during MB (CB) operation, the number of sliding symbols on the left reel 3L is determined. The maximum number is determined for one symbol. Therefore, when the left stop button 17L is pressed, the symbol of the left reel 3L located in the area (for example, the upper stage) on the winning determination line in the left display window 4L and the range up to four or one ahead The symbol existing in the left display window 4L becomes a symbol that can be stopped in the region.

<Configuration of data table stored in main ROM>
Next, the configuration of various data tables stored in the main ROM 52 will be described with reference to FIGS.

[Design arrangement table]
First, the symbol arrangement table will be described with reference to FIG. The symbol arrangement table is data (hereinafter referred to as symbol code (in FIG. 6) that specifies the position of each symbol in the rotation direction of each of the left reel 3L, the middle reel 3C, and the right reel 3R and the type of symbol arranged at each position. )))).

  In the symbol arrangement table, when a reel index is detected, the positions of symbols arranged in the middle region are defined as “0” in each of the left display window 4L, the middle display window 4C, and the right display window 4R. Then, in each reel, “0” to “20” corresponding to the symbol counter are set as symbol positions in the order of advance in the reel rotation direction (direction of arrow A in FIG. 6) with reference to symbol position “0”. Assigned to a symbol.

  That is, by referring to the symbol counter values ("0" to "20") and the symbol arrangement table, the types of symbols displayed in the upper, middle, and lower regions of each display window are specified. be able to. For example, when the value of the symbol counter corresponding to the left reel 3L is “6”, the upper, middle, and lower regions of the left display window 4L have “wing” and symbol position “7” in the symbol position “7”, respectively. Symbols corresponding to “BAR” of “6” and “Blank” of symbol position “5” are displayed.

[Design combination table]
Next, the symbol combination table will be described with reference to FIG. The symbol combination table defines a correspondence relationship between a symbol combination predetermined according to the type of privilege, a display combination (storage area), and a payout number.

  In the present embodiment, the winning combination is determined when the symbol combination displayed by the left reel 3L, the middle reel 3C, and the right reel 3R matches the symbol combination specified in the symbol combination table along the winning determination line. Is done. When it is determined that a prize is won, the player is given benefits such as a medal payout, a re-game operation, and a bonus game operation. If the symbol combination displayed along the winning determination line does not match any of the symbol combinations defined in the symbol combination table, it is a so-called “losing”. That is, in this embodiment, the symbol combination corresponding to “losing” is not defined in the symbol combination table, thereby defining the symbol combination “losing”. Note that the present invention is not limited to this, and the item “losing” may be provided in the symbol combination table to directly define “losing”.

  Various data described in the display combination column in the symbol combination table is data for identifying a symbol combination displayed along the winning determination line. “Data” in the display combination column is represented by 1-byte data, and a unique symbol combination (content of display combination) is assigned to each bit in the data.

  The “storage area” data in the display combination column is data for designating a later-described display combination storage area (see FIG. 25) in which the corresponding display combination is stored. In the present embodiment, three display combination storage areas are provided. In the present embodiment, display combinations having the same bit pattern (1-byte data pattern) and having different contents are managed as different display combinations depending on the “storage area”.

  The numerical value described in the payout number column in the symbol combination table represents the number of medals to be paid out to the player. In the combination of symbols to which a numerical value of 1 or more is given as the “paid-out number” data, the same number of medals are paid out. In the present embodiment, when any one of “Bell 1” to “Bell 10” is determined as the display combination, medals are paid out. In the present embodiment, the display combination from which these medals are paid out is collectively referred to as “small combination”.

  Further, in the present embodiment, when “replay” is determined as the display combination, the re-game is performed. Further, when “RB” is determined as the display combination, the regular bonus game is activated, and when “MB” is determined, the middle bonus game is activated.

[Bonus operating table]
Next, the bonus operation time table will be described with reference to FIG. The bonus operation time table defines data stored in a game state flag storage area (see FIG. 26), which will be described later, provided in the main RAM 53, a bonus end number counter, a game possible number counter, and a winning number counter during a bonus game. .

  The game state flag is data for identifying the type of bonus game being operated. In the present embodiment, a regular bonus (“RB”: second special internal winning combination) and a middle bonus (“MB”: first special internal winning combination) are provided as bonus game types. Note that “RB” is a so-called first type special combination. Further, “MB” is called an accessory continuous operation device related to the second type special accessory, and continuously operates “CB” which is the second type special accessory.

  The bonus end number counter is data for managing whether or not the number of medals paid out has reached a prescribed number (payout number) that triggers the end of the bonus game. In the present embodiment, the operation of “MB” ends when the medals that reach the prescribed number “90” are paid out.

  Specifically, first, the value of the bonus end number counter defined in the bonus operation time table is actually stored in the bonus end number counter. Next, after the MB operation, every time a medal is paid out, the value of the bonus end number counter is subtracted. Then, the operation of “MB” ends on condition that the value of the bonus end number counter is updated to “0”.

  The game possible number counter is data for managing the number of remaining games that can be played at the time of RB operation, so-called possible number of games. The winning possible number counter is data for managing the number of remaining games that can display a combination of symbols related to winning at the time of RB operation, so-called winning possible number.

[RT transition table]
Next, the RT transition table will be described with reference to FIG. The RT transition table defines the correspondence relationship between the RT gaming state transition condition and the destination RT gaming state. In the present embodiment, two types of gaming states, RT0 gaming state (normal gaming state) and RT1 gaming state (replay high probability gaming state), are provided as RT gaming states. In the RT1 gaming state, an internal lottery table, which will be described later, is set so that the winning probability of “replay” (replaying) is higher than that in the RT0 gaming state.

  In the present embodiment, when the symbol combination corresponding to “RB” is displayed on the winning determination line during the RT1 gaming state, the RT gaming state shifts from the RT1 gaming state to the RT0 gaming state. Further, when “RB” is won during the RT0 gaming state and the symbol combination corresponding to “RB” is not displayed on the winning determination line, the RT gaming state is changed from the RT0 gaming state to the RT1 gaming. Transition to the state. The transition process of the RT gaming state when “RB” is won during the RT0 gaming state and the symbol combination corresponding to “RB” is displayed on the winning determination line is as follows. In this case, first, when “RB” is won during the RT0 gaming state, the RT gaming state shifts from the RT0 gaming state to the RT1 gaming state. Next, when the symbol combination corresponding to “RB” is displayed on the winning determination line, the RT gaming state shifts from the RT1 gaming state to the RT0 gaming state. That is, in this case, the internal lottery process based on the RT1 gaming state is not performed, and it is substantially equivalent to no transition of the RT gaming state.

  Therefore, in the present embodiment, the period from the winning of “RB” until the symbol combination corresponding to “RB” is stopped and displayed (drawn), that is, the period in which the flag of “RB gaming state” is set. (Hereinafter referred to as between RB flags), the gaming state becomes the RT1 gaming state in which the winning probability of “replay” is high. Here, the example in which the transition of the RT gaming state is performed at the time of the reel stop display has been described, but the present invention is not limited to this, and the transition of the RT gaming state by the winning of “RB” is determined as the internal winning combination It may be performed at the time (in the internal lottery process).

[Internal lottery table determination table]
Next, the internal lottery table determination table will be described with reference to FIG. The internal lottery table determination table defines the correspondence between the internal lottery table used in various gaming states and the number of lotteries.

  For example, when the game state is a general game (non-bonus game) state, a general game state internal lottery table (RT0: see FIG. 11) described later is used, and “7” is set as the number of lotteries. Further, when the gaming state is the RB gaming state, an RB gaming state internal lottery table (see FIG. 13) described later is used, and “7” is set as the number of lotteries. In the present embodiment, when the gaming state is the MB gaming state, the internal lottery table (RT0) for the general gaming state is used as the internal lottery table.

[Internal lottery table]
Next, the internal lottery table will be described with reference to FIGS. The internal lottery table defines the correspondence between the data pointer and the lottery value when this data pointer is determined in various winning numbers.

  The data pointer is data acquired as a result of lottery performed with reference to the internal lottery table, and is data for designating an internal winning combination specified by an internal winning combination determination table (see FIGS. 14 and 15) described later. It is. The data pointer is provided with a small role / replay data pointer and a bonus data pointer. The lottery value is defined for each setting (settings 1 to 6) for adjusting the expected value of the lottery set in advance.

  In the internal lottery processing of the present embodiment, first, random numbers extracted from a predetermined numerical range (for example, 0 to 65535) are sequentially subtracted by lottery values defined corresponding to each winning number. Next, it is determined (internal lottery) whether the result of the subtraction has become negative (whether a so-called “digit” has occurred). When the result of subtraction becomes negative (a “digit” occurs) at a predetermined winning number, it means that the winning number is won, and the data point assigned to the corresponding winning number is acquired.

  Therefore, in the internal lottery process according to the present embodiment, the larger the number specified as the lottery value, the higher the probability that assigned data (that is, the data pointer) is determined. The winning probability of each winning number can be represented by “the lottery value defined for each winning number / the number of all random numbers that may be extracted (65536)”.

  FIG. 11 is a diagram illustrating a configuration of the internal lottery table (RT0) for the general gaming state. This internal lottery table for general gaming state is used when the gaming state is the general gaming state (non-bonus) and the RT0 gaming state.

  The internal lottery table for the general gaming state defines the relationship between the lottery value corresponding to the winning numbers “1” to “7” and the data pointer. For example, in the general gaming state, when referring to the general gaming state internal lottery table, the probability that the winning number “2” is won and “2” is acquired as the small role / replay data pointer is “10000 / 65536 ".

  In the internal game state internal lottery table, the small role / replay data pointer “1” corresponds to “replay”, “2” corresponds to “bell 1” to “bell 9”, and “3 "Corresponds to" bell 9 "+" bell 10 ". Further, the bonus data pointer “1” corresponds to “RB”, and “2” corresponds to “MB”.

  That is, in this embodiment, the internal winning combination of the winning number “1” is “Replay”, the internal winning combinations of the winning number “2” are “Bell 1” to “Bell 9”, and the winning number “3” "Bell 9" and "Bell 10" are internal winning combinations. The internal winning combination with the winning number “4” is “RB”, and the internal winning combination with the winning number “5” is “MB”. Further, the internal winning combination of the winning number “6” is “MB” and “Replay”, and the internal winning combinations of the winning number “7” are “MB”, “Bell 9”, and “Bell 10”. In the present embodiment, “RB” and another combination (small combination / replay) are not duplicated and won.

  FIG. 12 is a diagram illustrating a configuration of an RT1 internal lottery table that is referred to when the gaming state is the general gaming state and the RT1 gaming state. The RT1 internal lottery table defines the relationship between the lottery value and the data pointer at the winning number “1”.

  When the RT1 internal lottery table is selected, the lottery value defined in the winning number “1” in the general gaming state internal lottery table shown in FIG. 11 is the lottery value defined in the RT1 internal lottery table. To be rewritten. As a result, the probability of the internal winning combination (winning number “1”) related to the replay that can be won is changed. At this time, the same lottery value is used without changing the lottery values of the winning numbers “2” to “7” in the internal lottery table for the general gaming state.

  In the present embodiment, when the RT1 gaming state is entered, the probability of the internal winning combination (winning number “1”) related to replaying is “53500/65536”, which is that of the RT0 gaming state (normal gaming state) (9000). / 65536: predetermined probability). In the present embodiment, in the RT0 gaming state, for example, the sum of the lottery values of the winning numbers of setting 1 is “20406”, and the probability of “losing” is “45130/65536”. On the other hand, in the RT1 gaming state, for example, the sum of the lottery values of the winning numbers of setting 1 is “64906”, and the probability of “losing” is “630/65536”, which is much larger than that in the RT0 gaming state. descend.

  In the present embodiment, in the standard game state internal lottery table (RT0) serving as a reference, a table in which only the lottery value of “replay (winning number“ 1 ”)” is defined according to the RT game state is used. Although only the lottery value of “Replay” is changed, the present invention is not limited to this. Apart from the RT0 internal lottery table (general gaming state internal lottery table), an RT1 internal lottery table that defines the relationship between lottery values and data pointers for all winning numbers may be provided.

  FIG. 13 is a diagram illustrating a configuration of an internal lottery table for an RB gaming state. This internal lottery table for RB gaming state is referred to when the gaming state is the RB gaming state. The internal lottery table for RB gaming state defines the correspondence between lottery values and data pointers corresponding to the winning numbers “1” to “7”. In the present embodiment, the sum of the lottery values of the winning numbers 1 to 7 defined in the RB gaming state internal lottery table is “20411”. Therefore, in this embodiment, when referring to the RB gaming state internal lottery table, “losing” occurs with a probability of “45125/65536”.

[Internal winning combination determination table]
Next, the internal winning combination determination table will be described with reference to FIGS. The internal winning combination determination table defines the correspondence between the data pointer and the internal winning combination. That is, when the data pointer is determined, the internal winning combination data is uniquely acquired by the internal winning combination determination table.

  The “internal winning combination” in the internal winning combination determination table is data for identifying a combination of symbols on the left reel 3L, middle reel 3C, and right reel 3R that is permitted to be displayed along the winning determination line. The “internal winning combination” is represented by 1-byte data in the same way as the “display combination” in the symbol combination table shown in FIG. 7, and a unique symbol combination is assigned to each bit in the 1-byte data. Assigned. When the data pointer is “0”, the content of “internal winning combination” is “losing”. This is because all symbol combinations specified by the symbol combination table shown in FIG. 7 are displayed. Indicates that it is not allowed.

  FIG. 14 is a diagram showing the configuration of the bonus internal winning combination determination table. The bonus internal winning combination determination table defines internal winning combinations related to the operation of the bonus game for the bonus data pointers “1” and “2”. In the bonus internal winning combination determination table, “◯” indicates an internal winning combination to be won in the acquired bonus data pointer. For example, when “1” is acquired as the bonus data pointer, “RB” is won as the internal winning combination.

  FIG. 15 is a diagram showing a configuration of a small winning combination / replay internal winning combination determining table. The small winning combination / replay internal winning combination determining table defines small winning combinations and replay winning combinations for “1” to “3” of the small winning combination / replay data pointers. That is, the small winning combination / replay internal winning combination determination table defines a correspondence relationship between the small winning combination / replay data pointer and the internal winning combination relating to the payout of medals or the internal winning combination relating to the replay operation.

  The symbol “◯” in the small winning combination / replay winning symbol determination table indicates the internal winning combination to be won in the acquired small winning combination / replay data pointer. In the present embodiment, when “2” is acquired as the small combination / replay data pointer, “Bell 1” to “Bell 9” are won as internal winning combinations, and the small combination / replay data When “3” is acquired as the pointer, “Bell 9” and “Bell 10” are duplicated as internal winning combinations.

[Cylinder stop number selection table]
Next, with reference to FIG. 16, the rotating cylinder stop number selection table will be described. The rotation stop number selection table defines the correspondence between the small role / replay data pointer and the rotation stop number. The rotation stop number is data used when acquiring various data required in the reel stop initial setting process described later.

  In the present embodiment, the spinning cylinder stop number selection table defines different spinning cylinder stop numbers for each small role / replay data pointer. In the present embodiment, when MB (CB) is in operation and “RB” is non-winning, the rotation stop number “4” corresponding to “* 1” in the small role / replay data pointer column is selected. . Further, when “RB” is won during the MB (CB) operation, the rotation stop number “5” corresponding to “* 2” in the data pointer column for the small role / replay is selected.

  As will be described later, in the present embodiment, all MBs are won during the MB (CB) operation. Therefore, the small pointer / replay data pointer column ("* 1" and "* 2") corresponding to the rotating stop number "4" and "5" in the rotating stop number selection table is optional. The data pointer for the small role / replay can be set.

  As described above, in the present embodiment, the example of specifying a different rotation stop number for each small role / replay data pointer is shown as the rotation stop number selection table, but the present invention is not limited to this. . The same rotation stop number may be defined for different small role / replay data pointers to reduce data.

[Reel stop initial setting table]
Next, the reel stop initial setting table will be described with reference to FIG. The reel stop initial setting table defines a correspondence relationship between the rotation stop number and various data used in a pull-in priority table selection process described later and a number of sliding pieces determination process of each reel described later. Specifically, the reel stop initial setting table defines the correspondence relationship between the spinning stop number, the pull-in priority table number, the pull-in priority table selection data, and the stop table group number.

  The drawing priority table number and the drawing priority table selection data are data used for the drawing priority table selection process. For example, in the reel stop initial setting table, if a pull-in priority table number corresponding to the number for turning stop is specified (for example, numbers for turning stop “0”, “1”, “2”, “4”). ]), The pull-in priority table (see FIGS. 20 and 21) corresponding to the specified pull-in priority table number is selected. Further, if the pull-in priority table number corresponding to the turn-stop number is not defined in the reel stop initial setting table (for example, the turn-stop numbers “3” and “5”), the pull-in priority table is selected. With reference to the pull-in priority table selection table (see FIG. 19) corresponding to the data, the pull-in priority table number is determined.

  Further, the stop table group number is data used for the process of determining the number of sliding pieces of each reel, and a stop table group (see FIG. 18) corresponding to the stop table group number is selected.

[Stop table]
Next, an example of a stop table included in the stop table group will be described with reference to FIG. The stop table shown in FIG. 18 is the first stop table for the left reel, and is referred to when the stop table group number is “0”.

  The left reel first stop stop table defines a correspondence relationship between the stop start positions “0” to “20” of the left reel 3L and the sliding piece number determination data when the left reel 3L is first pushed. . The left reel first stop stop table shown in FIG. 18 is a table that is referred to when the number-of-sliding piece determination data is acquired in the general gaming state, and therefore the maximum number of sliding pieces is “4”. .

  The stop table group provided for each stop table group number includes a stop table provided corresponding to each reel and each stop order (not shown). Further, FIG. 18 shows an example in which stop tables are individually provided, but the present invention is not limited to this. For example, a plurality of stop tables may be combined into one table in association with conditions such as stop table group, reel type, stop order, and the like.

  Further, since the maximum number of sliding pieces of the left reel 3L during MB (CB) operation is one frame, although not shown here, the number of sliding pieces in the left reel first stop stop table referred to during the MB operation. In the decision data, “1” or “0” is defined.

[Pull-in priority table selection table]
Next, the pull-in priority table selection table will be described with reference to FIG. The pull-in priority table selection table defines the correspondence between the pressing order of the stop buttons and the pull-in priority table number in each stop operation. The pull-in priority table number is data for designating a pull-in priority table to be referred to (see FIGS. 20 and 21).

  The pull-in priority table selection table shown in FIG. 19 is referred to when the pull-in priority table selection data is “1”. The case where “1” is determined as the pull-in priority order table selection data is, for example, when the turning stop number is “5” (see FIG. 17). Further, when the turning stop number is “5”, the small role / replay data pointer is “* 2” (see FIG. 16). In other words, in the present embodiment, when “RB” is won during the MB (CB) operation, the pull-in priority table selection table shown in FIG. 19 is referred to.

  When “RB” is won during MB (CB) operation, when a stop operation is performed from the left reel 3L, “1” is set as the drawing priority table number as shown in the drawing priority table selection table of FIG. To be acquired. In this case, a pull-in priority table in FIG. 21 described later corresponding to the pull-in priority table number “1” is referred to, and “bell 9” is replaced with “bell” (“bell 1” to “bell 8” other than “bell 9”. ”,“ Bell 10 ”), and the control to stop display is performed.

  On the other hand, when “RB” is won during MB (CB) operation, if a stop operation is performed from the middle reel 3C or the right reel 3R, a drawing priority table as shown in the drawing priority table selection table of FIG. “0” is acquired as the number. In this case, a pull-in priority table in FIG. 20 described later corresponding to the pull-in priority table number “0” is referred to, and “bell” (“bell 1” to “bell 8”, “bell 10” other than “bell 9” is referred to. ")" Is controlled so as to be stopped and displayed over "Bell 9".

  Although not shown here, when the pull-in priority table selection data is “0” (when the small role / replay data pointer is “3”: the internal winning combination is “Bell 9” and “Bell 10”. (See FIGS. 15 and 16), the pull-in priority table selection table changes the pull-in priority table number value “1” to “0” in the pull-in priority table selection table shown in FIG. The table is obtained by changing the numerical value “0” to “1”. Therefore, when the pull-in priority table selection data is “0” and a stop operation is performed from the left reel 3L, control is performed to stop and display “Bell 10” in preference to “Bell 9”. . In addition, when the pull-in priority table selection data is “0” and the stop operation is performed from the middle reel 3C or the right reel 3R, the control is performed so that “bell 9” is stopped and displayed with priority over “bell 10”. Done.

[Pull-in priority table]
Next, the drawing priority table will be described with reference to FIGS. The pull-in priority table defines the correspondence between the pull-in data for each type in the storage area and the predetermined priority.

  The pull-in priority order table is used for searching whether there is a more appropriate number of sliding pieces in addition to the number of sliding pieces obtained based on the stop table. The priority order is data that defines the order of priority stop display (drawn) between the types of symbol combinations related to winning. Each pull-in data is 1-byte data as in the “internal winning combination” in the internal winning combination determination table shown in FIGS. 14 and 15 and the “display combination” in the symbol combination table shown in FIG. A unique symbol combination is assigned to each bit in the 1-byte data.

  In the present embodiment, first, the number of sliding pieces is acquired based on the above-described left reel first stop stop table (see FIG. 18). However, when there is a more appropriate number of sliding pieces in addition to the number of sliding pieces, the number is changed to the appropriate number of sliding pieces. In other words, in the present embodiment, a more appropriate number of sliding symbols is determined based on the priority of the combination of symbols permitted to be displayed by the internal winning combination regardless of the number of sliding symbols acquired from the stop table.

  The pull-in priority table shown in FIG. 20 is a table that is referred to when the pull-in priority table number is “0”, and priorities (“1” to “4”) and pull-in data in various internal winning combinations. Stipulates the correspondence with

  In the pull-in priority table shown in FIG. 20, the pull-in data corresponding to “Replay” is defined for the priority “1”, and “Bell 1” to “Bell 8” and “Bell” for the priority “2”. The pull-in data corresponding to “10” is defined. In addition, the pull-in data corresponding to “Bell 9” is defined for priority “3”, and the pull-in data corresponding to “MB” and “RB” is defined for priority “4”. Therefore, when the pull-in priority table number is “0” and the pull-in priority table shown in FIG. 20 is referred to, the symbol combination display (withdrawal) corresponding to “Replay” is displayed in other symbols. This is given priority over the display of the combination.

  The pull-in priority table shown in FIG. 21 is a table that is referred to when the pull-in priority table number is “1”, and priorities (“1” to “4”) in various internal winning combinations, Define the correspondence with the incoming data.

  In the pull-in priority table shown in FIG. 21, the pull-in data corresponding to “Replay” is defined for the priority “1”, and the pull-in data corresponding to “Bell 9” is defined for the priority “2”. . Also, for the priority “3”, the pull-in data corresponding to “Bell 1” to “Bell 8” and “Bell 10” is defined, and for the priority “4”, “MB” and “RB” are supported. Specify the pull-in data. Therefore, in the present embodiment, even when the drawing priority table number is “1” and the drawing priority table shown in FIG. 21 is referred to, the combination of symbols corresponding to “Replay” is displayed (drawing). However, it is performed with priority over the display of other symbol combinations.

[Search order table]
Next, the search order table will be described with reference to FIGS. The search order table preferentially applies from the range of numerical values predetermined as the number of sliding frames (“0” to “4” when the maximum number of sliding frames is 4) (hereinafter referred to as “search order”). "). Note that the search order table shown in FIG. 22 is a table that is referred to when stop control is performed with the maximum number of sliding frames being four. The search order table shown in FIG. 23 is a table that is referred to when stop control is performed with the maximum number of sliding symbols as one frame (when the number of sliding symbols on the left reel 3L is determined during MB operation).

  The search order table defines the number of sliding piece determination data obtained based on the stop table and the search order. That is, in this embodiment, the order of numerical values to be preferentially applied is determined based on the sliding piece number determination data. In addition, the search order table is provided assuming that there are a plurality of sliding frames having the same priority, and the search order table is applied in a higher order.

  In the present embodiment, as described in the priority attraction-in control process of FIG. 42 described later, each numerical value is sequentially searched from the search order “5” in the lower order of the search order table to correspond to the search order “1”. The number of sliding frames is preferentially applied from the numerical value to be used.

  Further, in this embodiment, the maximum number of sliding pieces of the left reel 3L during MB (CB) operation is one frame, but the stop control is performed with the maximum number of sliding pieces of 4 frames for the middle reel 3C and the right reel 3R. I do. Therefore, when determining the number of sliding pieces of the middle reel 3C and the right reel 3R during the MB (CB) operation, the search order table shown in FIG. 22 is referred to.

[Pattern winning action flag data table]
Next, the symbol corresponding winning action flag data table will be described with reference to FIG. The symbol corresponding winning action flag data table defines the correspondence between the reel type and the internal winning combination data that can be displayed according to the symbol of each reel displayed on the winning determination line. That is, by referring to the symbol corresponding winning action flag data table, the internal winning combination that can be displayed at that time can be determined. The symbol corresponding winning action flag data table is provided corresponding to the symbol combination table (see FIG. 7).

  For example, when the symbol “BAR” is stopped and displayed on the winning determination line of the left reel 3L, it can be displayed in the storage areas 1 to 3 corresponding to the symbol code “00000001” (BAR) in the reel type “left”. “1” is stored in the bit corresponding to the internal winning combination. The data defined in the symbol corresponding winning action flag data table is logically AND stored with data stored in a symbol code storage area (see FIG. 29) described later.

<Configuration of storage area provided in main RAM>
Next, the configuration of various storage areas provided in the main RAM 53 will be described with reference to FIGS.

[Display combination storage area]
First, the configuration of the display combination storage area will be described with reference to FIG. In the present embodiment, the display combination storage area includes display combination storage areas 1 to 3 each represented by 1-byte data.

  In each of the display combination storage areas 1 to 3, when a predetermined bit is set to “1” (stored), a combination of symbols corresponding to the predetermined bit is displayed on the winning determination line. It shows that. On the other hand, when all the bits are “0”, it indicates that the symbol combination related to winning or the symbol combination related to the operation of the bonus game is not displayed on the winning determination line.

  The main RAM 53 is provided with an internal winning combination storing area and a carryover combination storing area (not shown). The internal winning combination storing area has the same configuration as that of the display winning combination storage area shown in FIG. 25, and is configured by replacing the display winning combination storing areas 1 to 3 with the internal winning combination storing areas 1 to 3. In the internal winning combination storing areas 1 to 3, when “1” stands for a plurality of bits, display of a combination of symbols corresponding to each bit is permitted. When all the bits are “0”, the content of the internal winning combination is “lost”.

  Further, the carryover combination storage area is composed of only the storage area 1 of the display combination storage area shown in FIG. As a result of the internal lottery, when “RB” or “MB” is determined as the internal winning combination, the internal winning combination is stored in the carryover combination storage area as the carryover combination. Specifically, data “1” is stored in a bit corresponding to “RB” or “MB”. The carryover combination data stored in the carryover combination storage area is not cleared until the corresponding symbol combination (for example, “wing-feather-feather”) is displayed on the winning determination line. Further, while the carryover combination is stored in the carryover combination storage area (while the flag is set), the carryover combination is stored in the internal winning combination storage area in addition to the internal winning combination determined by the internal lottery. .

[Game state flag storage area]
Next, the configuration of the game state flag storage area will be described with reference to FIG. The gaming state flag storage area stores a gaming state flag consisting of 1 byte. In the gaming state flag, a bonus game type or an RT type is assigned to each bit.

  When “1” is stored (standing) in a predetermined bit in the game state flag storage area, it indicates that a bonus game or “RT” corresponding to the predetermined bit is being operated. For example, when “1” is set in bit 0 of the gaming state flag storage area, the operation of “MB” is performed and the state is the MB gaming state. In the present embodiment, when “0” is set in bit 3 of the gaming state flag storage area, it is determined that the player is in the RT0 gaming state.

[Operation stop button storage area]
Next, the configuration of the operation stop button storage area will be described with reference to FIG. The operation stop button storage area stores an operation stop button flag consisting of 1 byte. In the operation stop button flag, the operation state of the stop button is assigned to each bit.

  For example, if the left stop button 17L is a stop button that has been pressed this time, that is, an operation stop button, “1” is stored in bit 0 of the operation stop button storage area. Also, for example, if the left stop button 17L is a stop button that has not yet been pressed, that is, an effective stop button, “1” is stored in bit 4. Based on the data stored in the operation stop button storage area, the main CPU 51 identifies a stop button that has been pressed this time and a stop button that has not yet been pressed.

[Push order storage area]
Next, the configuration of the pressing order storage area will be described with reference to FIG. The pressing order storage area stores a pressing order flag consisting of 1 byte. In the pressing order flag, the type of stop button pressing order is assigned to each bit. For example, when the pressing order of the stop button is “left middle right”, “1” is stored in bit 0 of the pressing order storage area.

[Design code storage area]
Next, the configuration of the symbol code storage area will be described with reference to FIG. In the symbol code storage area, for each winning determination line, the symbol code (symbol code storage region 1) of the symbol of the reel that has been stopped most recently and the roles that can be displayed (symbol code storage regions 2 to 4) are stored. Is done. After all the reels are stopped, the symbol codes corresponding to the display combination are stored in the symbol code storage areas 2 to 4.

  In this embodiment, when the stop control position is determined, the winning operation flag data corresponding to the symbol (code) of the stop control position is read from the symbol corresponding winning operation flag data table (see FIG. 24), and the winning operation flag is read out. The data is ANDed with the data already stored in the symbol code storage area. Then, the ANDed data is stored in the symbol code storage area shown in FIG.

[Retrieve priority data storage area]
Next, the configuration of the pull-in priority data storage area will be described with reference to FIG. The pull-in priority data storage area includes a left reel pull-in priority data storage area, a middle reel pull-in priority data storage area, and a right reel pull-in priority data storage area. That is, in the pull-in priority data storage area, a priority data storage area is provided for each reel type.

  Each drawing priority order data storage area stores priority drawing order data determined according to each symbol position “0” to “20” of the corresponding reel. In the present embodiment, by referring to the pull-in priority data storage area, it is searched whether there is a more appropriate number of sliding symbols in addition to the number of sliding symbols determined based on the stop table described above.

  The contents of the priority pull-in data stored in the pull-in priority data storage area differ depending on the type of the pull-in priority table (see FIGS. 20 and 21) referred to when determining the priority pull-in data. The pull-in priority data storage area shown in FIG. 30 is a configuration example when the pull-in priority table number is “0”. In the pull-in priority data storage area of this example, bit 1 of the priority pull-in rank data corresponds to “MB” and “RB”, and bit 2 corresponds to “Bell 9”. Bit 3 corresponds to “bell 1” to “bell 8” and “bell 10”, and bit 4 corresponds to “replay”.

  Note that the “stoppable” data corresponding to bit 0 is data for loss. When a symbol at a predetermined symbol position is stopped and a combination of symbols corresponding to a winning combination that is not defined as an internal winning combination is displayed, “0” is set to bit 0 of the priority pull-in ranking data. Stored.

  The priority pull-in order data indicates that the higher the value, the higher the priority order. For example, in the pull-in priority data storage area shown in FIG. 30, the priority pull-in data with the highest priority is “00001111” (at least one of “MB” and “RB” + “Bell 1” to “Bell 10”. One or more of them + “replay”). On the other hand, the priority pull-in order data with the lowest priority is “00000000” (stop prohibition).

  By referring to the priority pull-in order data, it is possible to relatively evaluate the priority order among the symbols arranged on the peripheral surface of the reel. That is, the symbol for which the largest value is determined as the priority pull-in rank data is the symbol with the highest priority. Therefore, it can be said that the priority pull-in rank data indicates the rank between the symbols arranged on the peripheral surface of the reel. When there are a plurality of symbols having the same value of the priority pull-in order data, one symbol is determined according to the search order defined by the above-described search order table (see FIGS. 22 and 23).

<Description of main control circuit operation>
Next, contents of various processes executed by the main CPU 51 of the main control circuit 41 using a program will be described with reference to FIGS. 31 to 46.

[Main operation processing of pachislot by control of main CPU]
First, the procedure of main operation processing of the pachislot machine 1 performed under the control of the main CPU 51 will be described with reference to a main flowchart (hereinafter referred to as main flow) shown in FIG.

  First, when the power is turned on to the pachislot machine 1, the main CPU 51 performs an initialization process when the power is turned on (S1). In this initialization process, it is determined whether the backup has been normally performed, whether the setting has been changed appropriately, and the like, and initialization corresponding to the determination result is performed.

  Next, the main CPU 51 performs an initialization process at the end of one game (S2). In this initialization process, the data in the designated storage area in the main RAM 53 is cleared. Note that the designated storage area here is a storage area that needs to be erased for each game, such as an internal winning combination storage area or a display combination storage area.

  Next, the main CPU 51 performs medal acceptance / start check processing (S3). In this processing, input checks of the medal sensor 35S and the start switch 16S are performed. The details of the medal acceptance / start check process will be described later with reference to FIG.

  Next, the main CPU 51 extracts a random number value and stores the extracted random value in a random value storage area provided in the main RAM 53 (S4). When the extracted random number value is stored in the random value storage area, the main CPU 51 performs an internal lottery process (S5). In this process, the internal winning combination is determined by lottery based on a random value. Details of the internal lottery process will be described later with reference to FIGS. 33 and 34 to be described later.

  Next, the main CPU 51 performs a reel stop initial setting process (S6). Details of the reel stop initial setting process will be described later with reference to FIG.

  Next, the main CPU 51 performs a start command transmission process (S7). Specifically, the main CPU 51 transmits a start command to the sub control circuit 42. Note that the start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 51 performs a wait process (S8). In this process, when the predetermined time (for example, 4.1 seconds) has not elapsed since the start of the previous game, the main CPU 51 digests the waiting time until the predetermined time elapses.

  Next, the main CPU 51 performs a reel rotation start process (S9). In this process, the main CPU 51 requests the start of rotation of all reels. When the start of rotation of all reels is requested, driving of the three stepping motors 61L, 61C, and 61R is controlled by an interrupt process (see FIG. 46) described later that is executed at a constant cycle (1.1173 msec). Then, the rotation of the left reel 3L, the middle reel 3C, and the right reel 3R is started. At this time, each reel is subjected to acceleration control until the rotation speed reaches a constant speed, and then controlled so as to maintain the constant speed.

  Next, the main CPU 51 performs a pull-in priority storage process (S10). In this process, the main CPU 51 acquires the pull-in priority data and stores it in the pull-in priority data storage area. The details of the pull-in priority storage process will be described later with reference to FIG.

  Next, the main CPU 51 performs a reel stop control process (S11). In this process, the rotation of the corresponding reel is stopped based on the timing when the left stop button 17L, the middle stop button 17C, and the right stop button 17R are respectively pressed and the internal winning combination. The details of the reel stop control process will be described later with reference to FIG.

  Next, the main CPU 51 performs a winning search process (S12). In this process, the main CPU 51 stores the data in the symbol code storage area (after symbol code storage area 2 in FIG. 29) in the display combination storage area (see FIG. 25). In this process, the symbol combination displayed on the effective line (winning determination line) after all of the left reel 3L, the middle reel 3C and the right reel 3R are stopped is collated with the symbol combination table (see FIG. 7). . Then, the main CPU 51 may determine whether or not the display combination is displayed on the active line, and store the determination result in the display combination storage area.

  Next, the main CPU 51 performs a medal payout process (S13). In this process, the hopper 33 is driven and the number of credits is updated based on the number of payouts of the display combination determined in S12, and medals are paid out.

  Next, the main CPU 51 performs RT control processing (S14). In this process, the main CPU 51 manages the RT gaming state. Details of the RT control process will be described later with reference to FIG. 43 described later.

  Next, the main CPU 51 performs a bonus end check process (S15). In this process, the main CPU 51 refers to various counters for managing the end timing of the bonus game and checks whether or not the operation of the bonus game is to end. The details of the bonus end check process will be described later with reference to FIG. 44 described later.

  Next, the main CPU 51 performs a bonus operation check process (S16). In this process, the main CPU 51 checks whether or not to start the operation of the bonus game and whether or not to replay. The details of the bonus operation check process will be described later with reference to FIG. When the bonus operation check process ends, the main CPU 51 returns the process to S2, and repeats the processes after S2.

[Medal reception / start check processing]
Next, with reference to FIG. 32, the medal acceptance / start check process performed in S3 in the main flow (see FIG. 31) will be described.

  First, the main CPU 51 determines whether or not there is an automatic insertion request (S21). The presence / absence of the automatic insertion request is determined by determining whether or not the automatic insertion counter is “0”. That is, the main CPU 51 determines that there is no automatic insertion request when the automatic insertion counter is “0”, and automatically determines when the automatic insertion counter is “1” or more (“3” in this embodiment). It is determined that there is an input request.

  Note that the automatic insertion counter is data for identifying whether or not a display combination related to replay such as “replay” has been established in the previous unit game. When the display combination related to the re-game is established, the medals for the number of coins inserted in the previous unit game are automatically inserted into the automatic insertion counter.

  When the main CPU 51 determines in S21 that there is an automatic loading request (when S21 is YES), the main CPU 51 performs an automatic loading process (S22). In this process, the value of the automatic insertion counter is copied to the insertion number counter, and then the value of the automatic insertion counter is cleared. Thereafter, the main CPU 51 performs a process of S29 described later.

  On the other hand, when the main CPU 51 determines in S21 that there is no automatic insertion request (when S21 is NO), the main CPU 51 permits medal acceptance (S23). In this process, the solenoid of the selector 35 (see FIG. 3) is driven, and medals inserted from the medal insertion slot 11 are accepted. The received medals are counted and guided to the hopper 33.

  Next, the main CPU 51 sets the maximum number of inserted sheets according to the gaming state (S24). In the present embodiment, the maximum value of the inserted number is set to “3” in any of the general gaming state, the MB gaming state, and the RB gaming state.

  Next, the main CPU 51 determines whether or not the medal acceptance is permitted (S25). When the main CPU 51 determines in S25 that the medal acceptance is not permitted (when S25 is NO), the main CPU 51 performs a process of S29 described later.

  On the other hand, when the main CPU 51 determines in S25 that the medal acceptance is permitted (S25 is YES), the main CPU 51 performs a medal insertion check process (S26). In this process, the main CPU 51 determines whether or not a medal is inserted, and adds “1” to the inserted number counter when a medal is inserted.

  Next, the main CPU 51 transmits a medal insertion command to the sub control circuit 42 (S27). The medal insertion command includes a parameter for specifying the number of inserted coins.

  Next, the main CPU 51 determines whether or not the inserted number is a game start possible number (S28). In S28, when the main CPU 51 determines that the inserted number is not the game start possible number (when S28 is NO), the main CPU 51 returns the process to S25 and repeats the processes after S25. On the other hand, when the main CPU 51 determines in S28 that the inserted number is the game start possible number (when S28 is YES), the main CPU 51 performs the process of S29 described later.

  Next, the main CPU 51 determines whether or not the start switch is on (S29). When the main CPU 51 determines in S29 that the start switch is not on (when S29 is NO), the main CPU 51 returns the process to S25 and repeats the processes after S25.

  On the other hand, when the main CPU 51 determines in S29 that the start switch is on (when S29 is YES), the main CPU 51 performs a medal acceptance prohibition process (S30). By this process, the solenoid of the selector 35 (see FIG. 3) is not driven, and the inserted medal is discharged from the medal payout opening 18. When this process ends, the main CPU 51 ends the medal acceptance / start check process, and moves the process to S4 of the main flow (see FIG. 31).

[Internal lottery processing]
Next, with reference to FIGS. 33 and 34, the internal lottery process performed in S5 in the main flow (see FIG. 31) will be described. In the present embodiment, internal lottery processing using various internal lottery tables described below is executed by the main control circuit 41. That is, in the present embodiment, the main control circuit 41 also serves as means for executing internal lottery processing (internal winning combination determining means).

  First, the main CPU 51 sets an internal lottery table corresponding to the gaming state (S41). That is, the main CPU 51 grasps the current gaming state with reference to the gaming state flag storage area (see FIG. 26), and determines the type and number of lottery of the internal lottery table based on the internal lottery table determination table (see FIG. 10). decide. The number of lotteries indicates the number of times of lottery value subtraction and determination of whether or not a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 51 performs lottery value change processing (S42). In this process, the lottery value of the winning number relating to the replay or / and the small combination is changed according to the gaming state. The details of the lottery value changing process will be described later with reference to FIG.

  Next, the main CPU 51 acquires a random value stored in the random value storage area (S43). Then, the main CPU 51 sets “1” as the initial value of the winning number.

  Next, the main CPU 51 acquires a lottery value corresponding to the winning number with reference to the internal lottery table, and subtracts the lottery value from the random number value (S44).

  Next, the main CPU 51 determines whether or not the calculation result in S44 is 0 or more (S45).

  In S45, when the main CPU 51 determines that the calculation result is 0 or more (when S45 is YES), the main CPU 51 updates the random number value and the winning number (S46). Specifically, the value of the calculation result is set to a random value, and the winning number is incremented by one.

  Next, the main CPU 51 determines whether or not all winning numbers have been checked (S47). When it is determined in S47 that the main CPU 51 has not checked all the winning numbers (when S47 is NO), the main CPU 51 returns the process to S44 and repeats the processes after S44.

  On the other hand, when it is determined in S47 that the main CPU 51 has checked all the winning numbers (when S47 is YES), the main CPU 51 sets “0” as the data pointer (S48). That is, the main CPU 51 sets “0” as the small role / replay data pointer and the bonus data pointer.

  Here, returning to the description of the process of S45 again, in S45, when the main CPU 51 determines that the calculation result is less than 0 (negative value) (when S45 is NO), the main CPU 51 According to the winning number, a small role / replay data pointer and a bonus data pointer are acquired (S49).

  After the processing of S48 and S49, the main CPU 51 refers to the small winning combination / replay internal winning combination determination table (see FIG. 15), and acquires the internal winning combination based on the small winning combination / replay data pointer (S50). ).

  Next, the main CPU 51 refers to the gaming state flag storage area (see FIG. 26) to determine whether or not the CB gaming state flag is on (S51). In S51, when the main CPU 51 determines that the CB gaming state flag is not on (when S51 is NO), the main CPU 51 performs processing of S53 described later.

  On the other hand, when the main CPU 51 determines in S51 that the CB gaming state flag is on (in the case where S51 is YES), the main CPU 51 determines that all small roles ("Bell 1" to "Bell in the present embodiment) are selected. 10 ") is acquired (S52). Note that the processing of S51 and S52 does not need to be performed at this timing, and can be performed at any timing after S50.

  Next, the main CPU 51 stores the acquired internal winning combination in the internal winning combination storing area (S53).

  Next, the main CPU 51 determines whether or not the data stored in the carryover combination storage area is “00000000” (S54). In S54, when the main CPU 51 determines that the data stored in the carryover combination storage area is not “00000000” (when S54 is NO), the main CPU 51 performs the process of S58 described later.

  On the other hand, in S54, when the main CPU 51 determines that the data stored in the carryover combination storage area is “00000000” (in the case of YES determination in S54), the main CPU 51 determines the bonus internal winning combination determination table ( Referring to FIG. 14), an internal winning combination is acquired based on the bonus data pointer (S55).

  Next, the main CPU 51 stores the acquired internal winning combination in the carryover combination storing area (S56). In S55 and S56, the MB winning during the MB operation is invalidated, and in this case, the internal winning combination (“MB”) is not stored in the internal winning combination storing area and the carryover combination storing area (“MB” flag Do not stand).

  Next, the main CPU 51 clears bit 3 of the gaming state flag storage area (see FIG. 26) and the RT game number counter (S57). That is, by this process, the gaming state shifts from the RT1 gaming state to the RT0 gaming state.

  Next, the main CPU 51 updates the internal winning combination storing area based on the internal winning combination stored in the carryover combination storing area (S58).

  Next, the main CPU 51 determines whether or not the MB gaming state flag is ON and the internal winning combination is “RB” (S59). In S59, when the main CPU 51 determines that the condition that the MB gaming state flag is ON and the internal winning combination is “RB” is not satisfied (when S59 is NO), the main CPU 51 The lottery process is terminated, and the process proceeds to S6 of the main flow (see FIG. 31).

  On the other hand, when the main CPU 51 determines in S59 that the MB gaming state flag is ON and the internal winning combination is “RB” (when S59 is YES), the main CPU 51 performs the bonus end process. (S60). In this process, the main CPU 51 clears the bonus end number counter and turns off the MB gaming state flag. That is, in this embodiment, the MB gaming state flag is turned off by the internal lottery process. As will be described later with reference to FIG. 44, the CB gaming state flag is turned off in the bonus end check process (S191).

  Next, the main CPU 51 performs a bonus end command transmission process (S61). In this process, the main CPU 51 transmits a bonus end command to the sub-control circuit 42. The bonus end command includes information indicating that the bonus game has ended. Thereafter, the main CPU 51 ends the internal lottery process, and moves the process to S6 of the main flow (see FIG. 31).

[Lottery value change processing]
Next, with reference to FIG. 35, the lottery value changing process performed in S42 in the flowchart of the internal lottery process (see FIG. 33) will be described. In the present embodiment, the lottery value changing process described below is executed by the main control circuit 41. In other words, in the present embodiment, the main control circuit 41 also serves as means for executing lottery value change processing (replay probability changing means).

  First, the main CPU 51 refers to the gaming state flag storage area (see FIG. 26) and determines whether or not the RT1 gaming state flag is on (S71). In S71, when the main CPU 51 determines that the RT1 gaming state flag is not on (when S71 is NO), the main CPU 51 ends the lottery value changing process, and moves the process to S43 of the internal lottery process.

  On the other hand, when the main CPU 51 determines in S71 that the RT1 gaming state flag is on (when S71 is YES), the main CPU 51 uses the RT1 internal lottery table (see FIG. 12) to play a general game. The lottery value of the winning number “1” related to “Replay” in the state internal table (FIG. 11) is changed (S72). As a result, the winning probability of the winning number “1” related to “Replay” increases. Thereafter, the main CPU 51 ends the lottery value changing process, and moves the process to S43 of the internal lottery process (see FIG. 33).

[Reel stop initial setting process]
Next, the reel stop initial setting process performed in S6 in the main flow (see FIG. 31) will be described with reference to FIG.

  First, the main CPU 51 refers to the spinning cylinder stop number selection table (see FIG. 16), and acquires the spinning cylinder stop number based on the internal winning combination acquired in the internal lottery process of S5 (S81).

  Next, the main CPU 51 refers to the reel stop initial setting table (see FIG. 17), and acquires various information corresponding to the rotation stop number based on the acquired rotation stop number (S82). Specifically, the main CPU 51 acquires the drawing priority table number, the drawing priority table selection data, and the stop table group number corresponding to the acquired spinning cylinder stop number.

  Next, the main CPU 51 stores the rotating identifier “0FFH (11111111B)” in the entire symbol code storage area (see FIG. 29) (S83).

  Next, the main CPU 51 stores “3” in the stop button non-operating counter provided in the main RAM 53 (S84). Thereafter, the main CPU 51 ends the reel stop initial setting process, and moves the process to S7 of the main flow (see FIG. 31). The stop button non-operating counter is a counter for managing the number of stop buttons whose stop operation has not been detected.

[Retrieve priority storage processing]
Next, with reference to FIG. 37, a description will be given of the pull-in priority storage process performed in S10 in the main flow (see FIG. 31).

  First, the main CPU 51 stores the stop button non-operating counter in the main RAM 53 as the number of searches (S91). Next, the main CPU 51 performs a search target reel determination process (S92). In this process, for example, the main CPU 51 selects a predetermined reel from the rotating reels and determines the selected reel as a search target reel.

  For example, in S92, when all (three) reels are rotated, the left reel 3L is first determined as the search target reel. Thereafter, various processes up to S101 described later are performed on the left reel 3L. When the process returns to S92 again, the middle reel 3C is determined as a search target reel. Then, various processes up to S101 described later are performed on the middle reel 3C, and when returning to S92 again, the right reel 3R is next determined as a search target reel.

  Next, the main CPU 51 performs a pull-in priority table selection process (S93). In this process, the pull-in priority table is selected based on the internal winning combination (the small combination / replay data pointer) and the operation stop button. Details of the pull-in priority table selection process will be described later with reference to FIG.

  Next, the main CPU 51 sets “0” as the symbol position data and sets “21” as the symbol check count (S94). Then, the main CPU 51 performs a symbol code acquisition process (S95). In this process, the symbol code corresponding to the current symbol position data located on the effective line (winning determination line) of the search target reel is stored in the symbol code storage area. At this time, symbol codes for the number of valid lines are stored. Details of the symbol code acquisition process will be described later with reference to FIG.

  Next, the main CPU 51 updates the display combination storing area (see FIG. 25) based on the acquired symbol code and the data in the symbol code storing area (see FIG. 29) (S96). At this time, regardless of whether the internal winning combination is won or not, a combination of symbols that can be displayed (a displayable combination) is stored in the display combination storing area based on the stopped symbol.

  In this embodiment, the symbol code storage area information (symbol code and displayable role corresponding thereto) is updated for each reel to be stopped. At this time, the displayable combination may be obtained from data prepared in advance that defines the correspondence between the stopped reel symbol and the corresponding displayable combination, or the stopped reel symbol. And the symbol combination table (see FIG. 7). When the former method is used, the correspondence relationship between the symbol and the displayable combination changes for each reel.

  Next, the main CPU 51 performs a drawing priority order acquisition process (S97). In this process, for the combination whose bit is “1” in the display combination storage area (see FIG. 25) and whose bit is “1” in the internal winning combination storage area, the selected pull-in priority is selected. With reference to the rank table (see FIGS. 20 and 21), the pull-in priority data is acquired.

  Note that, when a symbol of a winning combination (for example, “Bell 9”) is displayed on some reels, the drawing priority data of the winning combination is not acquired for the reel “ANY”. Further, if there is a possibility that a winning combination that is not won internally is determined on a reel for which a winning is determined, the priority attraction ranking data is set to “stop prohibited (all bits 0)”.

  Next, the main CPU 51 stores the acquired priority pull-in rank data in the pull-in priority rank data storage area (see FIG. 30) (S98). At this time, the priority pull-in rank data is stored in the pull-in priority data storage area so that each priority value corresponds to a bit in the storage area. Next, the main CPU 51 adds 1 to the symbol position data and subtracts 1 from the number of symbol checks (S99).

  Next, the main CPU 51 determines whether or not the number of symbol checks is 0 (S100). In S100, when the main CPU 51 determines that the number of symbol checks is not 0 (when S100 is NO), the main CPU 51 returns the process to S95 and repeats the processes after S95.

  On the other hand, when the main CPU 51 determines that the number of symbol checks is 0 in S100 (when S100 is YES), the main CPU 51 determines whether or not the search has been performed for the number of searches (S101).

  In S101, when it is determined that the main CPU 51 has not searched the number of times of search (when S101 is NO), the main CPU 51 returns the process to S92 and repeats the processes after S92. On the other hand, when it is determined in S101 that the main CPU 51 has searched for the number of times of search (if S101 is YES), the main CPU 51 ends the pull-in priority storage process, and the process is S11 of the main flow (see FIG. 31). Move to.

[Pull-in priority table selection processing]
Next, with reference to FIG. 38, a description will be given of the pull-in priority table selection process performed in S93 in the flowchart of the pull-in priority storing process (see FIG. 37).

  First, the main CPU 51 determines whether or not the drawing priority table number is set, that is, whether or not the drawing priority table number is stored directly in the reel stop initial setting process (S6) (S111). ). When the main CPU 51 determines in S111 that the pull-in priority table number has been set (if S111 is YES), the main CPU 51 ends the pull-in priority table selection process and stores the pull-in priority order. The process proceeds to S94 of the process (see FIG. 37).

  On the other hand, when the main CPU 51 determines in S111 that the pull-in priority table number is not set (when S111 is NO), the main CPU 51 stores the pressing order storage area (see FIG. 28) and the operation stop button. Referring to the area (see FIG. 27), the corresponding drawing priority table number is set (S112). Thereafter, the main CPU 51 ends the pull-in priority order table selection process, and moves the process to S94 in the pull-in priority order storing process (see FIG. 37).

  In S112, first, the main CPU 51 refers to the pressing order storage area and the operation stop button storage area, and acquires the data of the pressing order and the operation stop button. Next, the main CPU 51 refers to the drawing priority table selection table corresponding to the drawing priority table selection data, and acquires the drawing priority table number based on the pressing order and the operation stop button. Thereafter, the main CPU 51 sets the acquired pull-in priority table number.

[Design code acquisition processing]
Next, with reference to FIG. 39, the symbol code acquisition process performed in S95 in the flowchart of the pull-in priority storage process (see FIG. 37) will be described.

  First, the main CPU 51 sets valid line data (S121). In the present embodiment, eight effective lines (winning determination lines) are provided as described above. Next, the main CPU 51 sets the symbol position data for checking the search target reel based on the search symbol position and the effective line data (S122). For example, if the effective line is [upper, upper, upper] (= [region of the left display window 4L, region of the middle display window 4C, region of the right display window 4R]), the upper line of the search target reel. Since it is desired to acquire information, the design symbol position data indicating the upper stage is set.

  Next, the main CPU 51 acquires the symbol code of the symbol position data for checking (S123). Thereafter, the main CPU 51 ends the symbol code storing process, and moves the process to S96 of the pull-in priority storing process (see FIG. 37).

[Reel stop control process]
Next, with reference to FIG. 40, the reel stop control process performed in S11 in the main flow (see FIG. 31) will be described. In the present embodiment, the reel stop control process described below is executed by the main control circuit 41. In other words, in the present embodiment, the main control circuit 41 also serves as means for executing reel stop control processing (stop control means).

  First, the main CPU 51 determines whether or not a valid stop button has been pressed (S131). In S131, when the main CPU 51 determines that the effective stop button is not pressed (in the case where S131 is NO), the main CPU 51 repeats the processing of S131 and the effective stop button is pressed. Wait until.

  On the other hand, when the main CPU 51 determines in S131 that a valid stop button has been pressed (in the case where S131 is YES), the main CPU 51 stores the pressing order storage area (see FIG. 28) and the operation stop button storage area (see FIG. 28). 27) is updated (S132). Next, the main CPU 51 decrements the stop button non-operating counter by 1 (S133).

  Next, the main CPU 51 determines a search target reel from the operation stop button (S134). Then, the main CPU 51 stores the stop start position in the main RAM 53 based on the symbol counter (S135).

  Next, the main CPU 51 performs a sliding piece number determination process (S136). The details of the sliding piece number determination process will be described later with reference to FIG. Next, the main CPU 51 transmits a reel stop command to the sub-control circuit 42 (S137). The reel stop command includes information such as the type of reel to be stopped and the number of sliding pieces.

  Next, the main CPU 51 determines a planned stop position based on the stop start position and the number of sliding pieces determined in S136, and stores the determined planned stop position in the main RAM 53 (S138). In this process, the main CPU 51 adds the number of sliding frames to the stop start position, and sets the result as the planned stop position.

  Next, the main CPU 51 sets the planned stop position determined in S138 as a search symbol position (S139). Next, the main CPU 51 performs the symbol code acquisition process described with reference to FIG. 39 (S140). Thereafter, the main CPU 51 updates the symbol code storage area (see FIG. 29) using the acquired symbol code (S141).

  Next, the main CPU 51 determines whether or not the stop button non-operation counter is 0 (S142).

  When the main CPU 51 determines in S142 that the stop button non-operation counter is not 0 (when S142 is NO), the main CPU 51 performs the pull-in priority storage process described with reference to FIG. 37 (S143). ). Thereafter, the main CPU 51 returns the process to S131 and repeats the processes after S131.

  On the other hand, when the main CPU 51 determines in S142 that the stop button non-operation counter is 0 (when S142 is YES), the main CPU 51 ends the reel stop control process, and the process proceeds to the main flow (FIG. 31). (Refer to S12).

[Sliding piece number determination processing]
Next, with reference to FIG. 41, the slip piece number determination process performed in S136 in the flowchart of the reel stop control process (see FIG. 40) will be described.

  First, the main CPU 51 sets the stop table (see FIG. 18) based on the number and the like of the pressing order storage area (see FIG. 28), the operation stop button storage area (see FIG. 27), and the stop table group (see FIG. 18). S151). Next, the main CPU 51 refers to the set stop table and acquires the number of sliding piece determination data corresponding to the stop start position stored in S135 (S152).

  Next, the main CPU 51 performs a priority pull-in control process (S153). Details of the priority pull-in control process will be described later with reference to FIG. After S153, the main CPU 51 ends the number-of-sliding piece determination process, and moves the process to S137 of the reel stop control process (see FIG. 40).

[Priority pull-in control processing]
Next, with reference to FIG. 42, the priority attraction-in control process performed in S153 in the flowchart (see FIG. 41) of the sliding piece number determination process will be described.

  First, the main CPU 51 sets a search order table (see FIGS. 22 and 23) according to the gaming state (S161). Next, the main CPU 51 sets initial values for the search order counter and the number of checks (S162). Specifically, the main CPU 51 sets “1” as an initial value in the search order counter. Further, the main CPU 51 sets the data length of the search order table as an initial value for the number of checks. Specifically, when the gaming state is the MB (CB) gaming state and the search target reel is the left reel 3L, “2” is set as the initial value of the number of checks, and in other cases “5” is set as the initial value of the number of checks.

  Next, the main CPU 51 sets the start address of a stop order table (not shown), and adds the address of the search order table based on the sliding piece number determination data (S163).

  Next, the main CPU 51 obtains the number of sliding symbols corresponding to the value of the search order counter (S164). Next, the main CPU 51 adds the acquired number of sliding frames to the expected stop start address, and acquires the priority pull-in rank data (S165).

  Next, the main CPU 51 determines whether or not the priority attraction ranking data acquired at S165 exceeds the priority attraction ranking data previously acquired (S166). In S166, when the main CPU 51 determines that the priority pull-in rank data acquired in S165 does not exceed the priority pull-in rank data acquired previously (when S166 is NO), the main CPU 51 performs the process of S168 described later. Do.

  On the other hand, in S166, when the main CPU 51 determines that the priority pull-in rank data acquired in S165 exceeds the priority pull-in rank data acquired in advance (when S166 is YES), the main CPU 51 detects the slip acquired in S164. The number of frames is saved (S167).

  Next, the main CPU 51 decrements the number of checks by 1, and increments the search order counter by 1 (S168).

  Next, the main CPU 51 determines whether or not the number of checks is “0” (S169). In S169, when the main CPU 51 determines that the number of checks is not “0” (when S169 is NO), the main CPU 51 returns the process to S164 and repeats the processes after S164.

  On the other hand, when the main CPU 51 determines that the number of checks is “0” in S169 (when S169 is YES), the main CPU 51 restores the number of sliding symbols that have been retreated (S170). Thereafter, the main CPU 51 ends the priority pull-in control process and also ends the sliding piece number determination process (see FIG. 41).

[RT control processing]
Next, the RT control process performed in S14 in the main flow (see FIG. 31) will be described with reference to FIG.

  First, the main CPU 51 refers to the RT transition table (see FIG. 9) and sets a gaming state flag based on the display combination (S181). At this time, the current RT gaming state flag is cleared, and the destination RT gaming state flag is set. For example, in the present embodiment, when the combination of symbols corresponding to “RB” is displayed on the winning determination line during the RT1 gaming state, the game state flag is shifted to the RT0 gaming state. Bit 3 of the storage area (see FIG. 26) is cleared, and bit 3 is set to “0”. On the other hand, if “RB” is won during the RT0 gaming state and the symbol combination corresponding to “RB” is not displayed on the winning determination line, the game moves to the RT1 gaming state. Clears bit 3 of the game state flag storage area (see FIG. 26) and sets bit 3 to “1”.

  Next, the main CPU 51 performs display command transmission processing (S182). In this process, the main CPU 51 transmits a display command to the sub control circuit 42. The display command includes parameters that specify a display combination, a payout number, and the like. Then, after S182, the main CPU 51 ends the RT control process, and moves the process to S15 of the main flow (see FIG. 31).

[Bonus end check process]
Next, with reference to FIG. 44, the bonus end check process performed in S15 in the main flow (see FIG. 31) will be described.

  First, the main CPU 51 turns off the CB gaming state flag (S191). Next, the main CPU 51 determines whether or not the gaming state is the MB gaming state with reference to the gaming state flag storage area (see FIG. 26) (S192). In S192, when the main CPU 51 determines that the gaming state is not the MB gaming state (when S192 is NO), the main CPU 51 performs a process of S197 described later.

  On the other hand, when the main CPU 51 determines in S192 that the gaming state is the MB gaming state (when S192 is YES), the main CPU 51 determines whether or not the bonus end number counter is less than 0 ( S193).

  In S193, when the main CPU 51 determines that the bonus end number counter is not less than 0 (when S193 is NO), the main CPU 51 performs the process of S197 described later. On the other hand, when the main CPU 51 determines in S193 that the bonus end number counter is less than 0 (YES in S193), the main CPU 51 performs bonus end time processing (S194). In this process, the main CPU 51 clears the bonus end number counter and turns off the MB gaming state flag. When the bonus end number counter is less than 0, it means that the payout of medals exceeds 90 during the MB gaming state.

  Next, the main CPU 51 performs a bonus end command transmission process (S195). In this process, the main CPU 51 transmits a bonus end command to the sub-control circuit 42. The bonus end command includes information indicating that the bonus game has ended.

  Next, the main CPU 51 performs initialization processing at the end of the bonus (S196). After S196, the main CPU 51 ends the bonus end check process and moves the process to S16 of the main flow (see FIG. 31).

  If S192 or S193 is NO, the main CPU 51 refers to the gaming state flag storage area (see FIG. 26) and determines whether or not the gaming state is the RB gaming state (S197). In S197, when the main CPU 51 determines that the gaming state is not the RB gaming state (when S197 is NO), the main CPU 51 ends the bonus end check process, and the process proceeds to S16 of the main flow (see FIG. 31). Move to.

  On the other hand, when the main CPU 51 determines that the gaming state is the RB gaming state in S197 (when S197 is YES), the main CPU 51 updates the winning possible number counter and the gaming possible number counter (S198). The winning possible number counter is decremented by “1” when a small combination (comb with a medal payout) is displayed. Further, the game possible number counter is decremented by “1” for one game regardless of the stop symbol.

  Next, the main CPU 51 determines whether or not the acquisition number counter or the possible game number counter is “0” (S199). In S199, when the main CPU 51 determines that the winable number counter and the possible game number counter are not “0” (when S199 is NO), the main CPU 51 ends the bonus end check process, and the main process is performed. The process proceeds to S16 of the flow (see FIG. 31).

  On the other hand, when the main CPU 51 determines in S199 that the winable number counter and the possible game number counter are “0” (when S199 is YES), the main CPU 51 performs an RB end process (S200). . Specifically, the main CPU 51 performs processing such as turning off the RB gaming state flag and clearing the winning possible number counter and the possible gaming number counter. After S200, the main CPU 51 ends the bonus end check process and moves the process to S16 of the main flow (see FIG. 31).

[Bonus activation check process]
Next, with reference to FIG. 45, the bonus end check process performed in S16 in the main flow (see FIG. 31) will be described.

  First, the main CPU 51 determines whether or not “MB” is operating (S211). In S211, when the main CPU 51 determines that “MB” is not in operation (NO in S211), the main CPU 51 performs the process of S214 described later.

  On the other hand, when the main CPU 51 determines in S211 that "MB" is in operation (if S211 is YES), the main CPU 51 determines whether or not "CB" is in operation (S212). ). In S212, when the main CPU 51 determines that “CB” is in operation (in the case where S212 is YES), the main CPU 51 ends the bonus operation check process and performs the process in the main flow (see FIG. 31). Move to S2.

  On the other hand, in S212, when the main CPU 51 determines that “CB” is not in operation (NO in S212), the main CPU 51 performs CB operation processing (S213). In this process, a flag is set on the bit (bit 1) of the CB gaming state in the gaming state flag storage area (see FIG. 26) ("1" is stored). Thereafter, the main CPU 51 ends the bonus operation check process, and moves the process to S2 of the main flow (see FIG. 31).

  If S211 is NO, the main CPU 51 determines whether or not the bonus game is winning (S214). In S214, when the main CPU 51 determines that the bonus game is not a prize (when S214 is NO), the main CPU 51 performs the process of S218 described later.

  When the main CPU 51 determines in S214 that the bonus game is a winning game (if S214 is YES), the main CPU 51 corresponds to the winning bonus game based on the bonus operating table (see FIG. 8). A bonus activation process is performed (S215).

  In the process of S214, when the bonus is “MB”, the main CPU 51 performs an MB operation process and a CB operation process. Specifically, the main CPU 51 sets “1” to bits 0 and 1 of the game state flag storage area (see FIG. 26), and sets the value of the bonus end number counter to “90”. On the other hand, when the bonus is “RB”, the main CPU 51 performs processing during RB operation. Specifically, the main CPU 51 sets “1” to bit 2 of the game state flag storage area (see FIG. 26), sets it to “3” in the possible game number counter, and further sets “ 3 ”is set.

  Next, the main CPU 51 clears the value of the carryover combination storage area (S216). Next, the main CPU 51 performs a bonus start command transmission process (S217). In this process, the main CPU 51 transmits a bonus start command to the sub-control circuit 42. The bonus start command includes information indicating that the bonus game has started. After S217, the main CPU 51 ends the bonus operation check process and moves the process to S2 of the main flow (see FIG. 31).

  When S214 is NO, the main CPU 51 determines whether or not “Replay” is a winning (S218). In S218, when the main CPU 51 determines that “Replay” is not a prize (when S218 is NO), the main CPU 51 ends the bonus operation check process, and the process proceeds to S2 of the main flow (see FIG. 31). Move.

  On the other hand, when the main CPU 51 determines that “Replay” is a win in S218 (when S218 is YES), the main CPU 51 requests automatic insertion of medals (S219). That is, the main CPU 51 copies the insertion number counter to the automatic insertion number counter. After S219, the main CPU 51 ends the bonus operation check process and moves the process to S2 of the main flow (see FIG. 31).

[Interrupt processing under the control of the main CPU (1.1173 msec)]
Next, with reference to FIG. 46, an interrupt process by the control of the main CPU 51 performed in S9 in the main flow (see FIG. 31) will be described.

  First, the main CPU 51 saves the register (S221). Next, the main CPU 51 performs an input port check process (S222). In this process, signals input from various switches such as the stop switch 17S are checked.

  Next, the main CPU 51 performs a reel control process (S223). In this process, the main CPU 51 starts rotation of the left reel 3L, the middle reel 3C, and the right reel 3R when the start of rotation of all the reels is requested, and thereafter, each reel rotates at a constant speed. The three stepping motors 61L, 61C, 61R are driven and controlled. When the number of sliding symbols is determined, the main CPU 51 updates the symbol counter of the corresponding reel by the number of sliding symbols. Then, the main CPU 51 waits for the updated symbol counter to match the value corresponding to the planned stop position (the symbol at the planned stop position reaches the area on the effective line (winning determination line) of the display window). The corresponding stepping motor is driven and controlled so that the rotation of the corresponding reel is decelerated and stopped.

  Next, the main CPU 51 performs a lamp and 7-segment driving process (S224). In this process, the main CPU 51 controls the 7-segment display 6 to display the number of payouts and the number of credits. Next, the main CPU 51 performs a register restoration process (S225). After that, the main CPU 51 ends the interrupt process.

Next, the contents of various processes (tasks) executed by the sub CPU 81 of the sub control circuit 42 using a program will be described with reference to FIGS.

[Main board communication task]
First, the main board communication task performed by the sub CPU 81 will be described with reference to FIG.

  First, the sub CPU 81 performs reception check of the command transmitted from the main control circuit 41 (S231). Next, when receiving a command, the sub CPU 81 extracts the type of the received command (S232).

  Next, the sub CPU 81 determines whether or not a command different from the previous one has been received (S233). When the sub CPU 81 determines in S233 that the command different from the previous command has not been received (when S233 is NO), the sub CPU 81 returns the process to S231 and repeats the processes after S231.

  On the other hand, when it is determined in S233 that the sub CPU 81 has received a command different from the previous command (when S233 is YES), the sub CPU 81 stores a message in the message queue based on the received command (S234). ).

In S242, when the sub CPU 81 determines that there is no message in the message queue (when S242 is NO), the sub CPU 81 performs a process of S245 described later.

  On the other hand, when the sub CPU 81 determines in S242 that there is a message in the message queue (when S242 is YES), the sub CPU 81 copies the game information from the message (S243). In this process, for example, various data such as an internal winning combination, a type of reel that has stopped rotating, a display combination, and a game state flag specified by parameters are copied to a storage area (not shown) provided in the sub RAM 83. The

  First, the sub CPU 81 determines whether a start command is received (S251).

  When the sub CPU 81 determines in S251 that the start command is being received (S251 is YES), the sub CPU 81 performs a start command receiving process (S252). In this process, the sub CPU 81 extracts a random number for production, determines the production number by lottery based on the internal winning combination and the like and registers it. Here, the production number is data for designating the production content to be executed this time.

  Next, the sub CPU 81 registers the production data at the start according to the registered production number (S253). The effect data is data that designates animation data, sound data, and lamp data. Therefore, when the effect data is registered, the corresponding animation data and the like are determined, and effects such as display of video are executed. Thereafter, the sub CPU 81 ends the effect content determination process, and moves the process to S245 of the effect registration task (see FIG. 48).

  When the sub CPU 81 determines in S254 that the reel stop command is being received (when S254 is YES), the sub CPU 81 determines whether or not to stop according to the registered production number and the type of the operation stop button. The effect data is registered (S255). Thereafter, the sub CPU 81 ends the effect content determination process, and moves the process to S245 of the effect registration task (see FIG. 48).

  On the other hand, when it is determined in S254 that the sub CPU 81 is not receiving a reel stop command (when S254 is NO), the sub CPU 81 determines whether or not it is a display command reception (S256).

  When the sub CPU 81 determines in S256 that the display command is being received (when S256 is YES), the sub CPU 81 performs a display command receiving process (S257). In this process, the sub CPU 81 shifts the production mode based on the gaming state, display combination, lottery, and the like.

  Next, the sub CPU 81 registers the effect data at the time of display according to the registered effect number and display combination (S258). Thereafter, the sub CPU 81 ends the effect content determination process, and moves the process to S245 of the effect registration task (see FIG. 48).

  On the other hand, when the sub CPU 81 determines in S256 that the display command is not received (NO in S256), the sub CPU 81 determines whether or not the bonus start command is received (S259).

  When the sub CPU 81 determines in S259 that the bonus start command is being received (when S259 is YES), the sub CPU 81 performs a predetermined reception process corresponding to the bonus start command (bonus start command reception process). (S260).

  Next, the sub CPU 81 registers effect data for starting a bonus (S261). Thereafter, the sub CPU 81 ends the effect content determination process, and moves the process to S245 of the effect registration task (see FIG. 48).

  On the other hand, when the sub CPU 81 determines in S259 that the bonus start command is not received (when S259 is NO), the sub CPU 81 determines whether or not the bonus end command is received (S262). When the sub CPU 81 determines that the bonus end command is not received at S262 (when S262 is NO), the sub CPU 81 ends the effect content determination process, and the process of the effect registration task (see FIG. 48). Move to S245.

  On the other hand, when the sub CPU 81 determines in S262 that the bonus end command is being received (S262 is YES), the sub CPU 81 performs a bonus end command receiving process (S263).

  Next, the sub CPU 81 registers effect data for bonus end (S264). Thereafter, the sub CPU 81 ends the effect content determination process, and moves the process to S245 of the effect registration task (see FIG. 48).

  In the pachi-slot 1 of the present embodiment, main operations are performed according to various processing procedures described with reference to FIGS.

<Stop display operation of “RB”>
Next, the stop display (retraction) operation of “RB” in the pachi-slot 1 according to the present embodiment will be described. In the stop display operation of “RB” in the present embodiment described below, the main control circuit 41 performs stop control of the left reel 3L, the middle reel 3C, and the right reel 3R via the motor drive circuit 62, respectively. It is realized by.

  First, the stop display operation of “RB” in a game state other than the MB game state (a game state in which stop control is performed with a maximum number of four sliding symbols) will be described. In this embodiment, when “RB” is won in a gaming state other than the MB gaming state (hereinafter referred to as a non-MB gaming state), a combination of symbols corresponding to “RB” (regardless of the timing of pressing the reel) “BAR” − “BAR” − “BAR”) is always stopped and displayed (withdrawn) (withdrawing rate 100%).

  Also, in this embodiment, when “RB” is won, as described in the internal lottery tables of FIGS. 11 and 12, the internal is not overlapped with other winning combinations (small role / replay). A lottery table is set.

  That is, in this embodiment, when “RB” is won in the non-MB gaming state, “RB” wins alone and a combination of symbols corresponding to “RB” (“BAR” − “BAR” − “ BAR ") is always displayed (becomes a display role). Therefore, in the present embodiment, when the gaming state is the non-MB gaming state, between the RB flags (the period during which the “RB gaming state” flag in the carryover combination storage area is set, that is, “RB” is substantially carried over. The period during which the state is reached does not occur.

  In the present embodiment, since a plurality of winning determination lines (effective lines) are provided, when “RB” is won in the non-MB gaming state, a symbol corresponding to “RB” in any of the plurality of winning determination lines. The symbol arrangement table (see FIG. 6) is set so that the combination of the symbols is always stopped and displayed. That is, in order to realize the stop display operation of the “RB” in the non-MB gaming state, in this embodiment, in each reel, a symbol (“BAR”) corresponding to “RB” is displayed on a plurality of winning determination lines. In any case, they are arranged at intervals that can be derived within a maximum number of sliding frames of 4 frames (first maximum delay time).

  Next, the stop display operation of “RB” when “RB” is won during the MB gaming state will be described. In the present embodiment, for example, an internal lottery table for general gaming state (RT0) as shown in FIG. 11 is used as an internal lottery table used during MB operation, so that “RB” is won and displayed in a stopped state during MB operation. Can do.

  However, since the left reel 3L is controlled to stop at the maximum number of sliding frames during MB operation, even if “RB” wins during MB operation, it is set to “RB” according to the timing of pressing the left reel 3L. Corresponding symbol combinations ("BAR"-"BAR"-"BAR") may not be stopped (a symbol combination different from the symbol combination corresponding to "RB" may be stopped). . That is, when “RB” is won during the MB operation, there may be an interval between RB flags (“RB” is a carryover state). In the present embodiment, when “losing” occurs between RB flags (RT1 gaming state), “RB” is stopped and displayed. Since “MB” ends when “RB” is won during MB operation, stop control of all reels is performed within the range of the maximum number of sliding frames of 4 frames between RB flags. Therefore, when “losing” occurs between the RB flags (RT1 gaming state), the symbol combination corresponding to the carryover combination “RB” is always stopped and displayed.

  In the present embodiment, in order to realize the stop display operation of “RB” in the MB gaming state, the symbol corresponding to “RB” (“BAR”) is displayed on the left reel 3L with a maximum number of sliding symbols of 1 frame. Arranged at intervals exceeding a derivable interval within the range of (second maximum delay time).

<Effect of the present invention>
In this embodiment, as described above, the RT1 operation condition is “RB” win (see the RT transition table in FIG. 9), and therefore, the “RT1 game” in which the “Replay” win probability increases between RB flags. State ". In other words, in the present embodiment, the MB operation period can be functioned as a period (chance zone) in which “RT1” can be operated in which the winning probability of “replay” is high. In addition, when RT1 is activated, the winning probability of “Replay” is higher, so it is possible to prevent the stop display (retraction) of the symbol combination corresponding to “RB” with a high probability (“RB” can be carried over). ), The RB flag (RT1 gaming state) can be continued longer. Therefore, in this embodiment, the interest of the game can be enhanced.

  Further, in the present embodiment, the condition for the RT1 operation is a winning combination (“RB”), so in the operation of “RT1”, the player is prevented from feeling distrust, and the fairness of the game is also improved. Can be secured.

<Various modifications>
The configuration and operation of the gaming machine (pachislot 1) according to the present invention are not limited to the above-described embodiment, and various modifications may be included without departing from the gist of the present invention described in the claims. Here, various modifications of the present invention will be described.

[Modification 1]
In the above embodiment, an internal lottery table (see FIGS. 11 and 12) between “RB flags” (RT1 gaming state), where “losing” occurs with a very low probability (“Replay” is won with a very high probability). An example has been described in which a combination of symbols corresponding to “RB” is stopped (drawn) only when “losing” occurs between RB flags, but the present invention is not limited to this.

  For example, as an internal lottery table referred to between RB flags, an internal lottery table in which lottery values are appropriately set so that “losing” does not occur may be used. In this case, when a small combination (“Bell 1” to “Bell 10” in the above embodiment) is missed between the RB flags (RT1 gaming state), for example, according to the reel stop operation order, “RB” The combination of symbols corresponding to "" may be stopped and displayed.

  For example, when the left reel 3L, the middle reel 3C, and the right reel 3R are stopped in a predetermined stop order between the RB flags (RT1 gaming state) (in the case of correct pushing order), a specific combination (small combination) In other stop orders (in the case of incorrect push order), one of the specific combination and “RB” is selectively displayed according to the timing of the stop operation.

  In this case, since a specific combination is displayed at the correct answer in the pressing order, it is possible to prevent the display (retraction) of “RB” (the “RB” can be carried over), and between the RB flags (RT1 game) State) can continue.

  On the other hand, when the pressing order is incorrect, a specific combination can be displayed if the timing of the stop operation is correct, and the display of “RB” can be prevented, but if the timing of the stop operation is shifted, “RB” ”Is stopped and displayed. Note that the stop display operation when the pressing order is incorrect can be performed as follows, for example. First, the symbol is stopped so that both the specific combination and “RB” can be displayed at the first stop of the reel. Next, it is determined whether or not a specific combination has been missed according to the timing of the stop operation after the second stop. Based on the determination result, the combination of symbols corresponding to one of the specific combination and “RB” is stopped and displayed.

  Even if such a stop control method is used, the display of “RB” between the RB flags can be avoided, and “RT1” in which the winning probability of “replay” is increased in the MB operation period as in the above embodiment. It can be made to function as an operable period (chance zone), and the interest of the game can be enhanced. Also in this example, instead of avoiding the display of “RB” by internal lottery, the display of “RB” is avoided as a result of displaying a specific winning combination between RB flags. Therefore, in this example as well, it is possible to prevent the player from feeling distrust with respect to the operation of “RT1” and to ensure the fairness of the game.

  In the present invention, when an internal lottery table in which “losing” occurs with a very low probability between RB flags (RT1 gaming state) as in the above embodiment, “losing” occurs between RB flags. The combination of symbols corresponding to “RB” may be stopped and displayed not only when it occurs, but also when a specific combination is missed in the pressing order.

[Modification 2]
In the above embodiment, in the above embodiment, the reel that reduces the maximum number of sliding pieces during the MB (CB) operation is only the left reel 3L. However, the present invention is not limited to this, and the maximum reel relative to other reels is not limited. The number of sliding pieces may be reduced. Further, during the MB (CB) operation, for example, the maximum number of sliding pieces may be reduced for a plurality of reels.

[Modification 3]
In the above embodiment, an example in which eight winning determination lines (effective lines) are provided has been described. However, the present invention is not limited to this, and the number of winning determination lines and the form of each line can be arbitrarily set. it can. Further, the arrangement and combination of symbols and the combination of internal winning combinations can be arbitrarily set as long as the stop display operation of “RB” is possible in the same manner as in the above embodiment.

[Modification 4]
In the above embodiment, an example in which only one type of “RB” is provided has been described. However, the present invention is not limited to this, and a plurality of types of “RB” may be provided.

  In this case, the winning probability of “Replay” may be changed for each type of “RB”. That is, a plurality of types of RT gaming states (for example, RT1 gaming state, RT2 gaming state, RT3 gaming state,...) In which the winning probability of “replay” is higher than that in the normal gaming state (for example, RT0 gaming state) may be provided. . Thereby, the occurrence probability of “losing” can be changed for each type of “RB”. That is, the probability that the gaming state (replay high probability gaming state) in which the symbol combination corresponding to “RB” is displayed and “Replay” is won with high probability can be changed for each type of “RB”. .

[Modification 5]
In the above embodiment, an example in which only one type of “MB” is provided has been described, but the present invention is not limited to this, and a plurality of types of “MB” may be provided.

  In this case, the number of games until the end of “MB” may be changed for each type of “MB” by changing the bonus end number counter and / or the payout number of the small role during MB operation. This makes it possible to change the degree of expectation of winning “RB” during MB operation for each type of “MB”. That is, the degree of expectation of transition to the RT1 gaming state during MB operation can be changed for each type of “MB”.

[Modification 6]
In the above-described embodiment, an example of shifting to the RT gaming state (RT1 gaming state) in which the winning probability of “replay” is higher between RB flags has been described, but the present invention is not limited to this. For example, “AT (assist time)” and “RT (RT1)” may be operated simultaneously between RB flags. That is, in the present invention, “ART” may be activated when “RB” is won during MB operation.

[Modification 7]
In the above embodiment, an example in which an internal lottery table for general gaming state (see FIGS. 11 and 12) referred to in the general gaming state (when non-bonus) is used as the internal lottery table during MB operation has been described. However, the present invention is not limited to this, and an internal lottery table for MB operation may be prepared separately.

[Modification 8]
In the above-described embodiment, an example in which “RB” is always won alone has been described. However, the present invention is not limited to this, and “RB” and other combinations may be won in duplicate with a low probability. Good.
