Description

  The present invention relates to a rotating game machine.

  Conventionally, a player's operation (hereinafter referred to as “medal etc.”) is provided on condition that a plurality of reels each having a plurality of symbols arranged on each surface are provided side by side and medals, coins (hereinafter referred to as “medals etc.”) are inserted. , "Start operation") and a start switch that outputs a signal requesting the start of rotation of all reels, and a player's operation (hereinafter referred to as "stop operation") is detected according to the type of reel And a stop switch for outputting a signal for requesting the rotation of the corresponding reel to stop, a plurality of corresponding stepping motors corresponding to each of the plurality of reels, each of which transmits a driving force to each reel, and the start Based on the signals output by the switch and the stop switch, the operation of the stepping motor is controlled, and a rotation unit including a control unit that rotates and stops each reel. Tricks machine is known. Normally, in such a spinning-type gaming machine, when rotation of all reels is stopped, whether or not a predetermined symbol combination is displayed to the player by the plurality of reels is determined. If it is determined that it is determined that the predetermined symbol combination is displayed, a so-called winning is established and a medal or the like is paid out.

  Such a swivel type gaming machine is usually provided with a symbol combination table that defines a plurality of predetermined symbol combinations, and the symbol combination displayed to the player is the symbol combination table. It is sequentially determined whether or not it matches each of the symbol combinations defined by the combination table, and the number of medals or the like corresponding to the symbol combination determined to match is paid out.

  At present, when a player's start operation is detected by a mainstream spinning machine, a random number is used for lottery, and the result of the lottery (hereinafter referred to as “internal winning combination”) and a stop operation by the player are performed. The rotation of the reel is stopped based on the detected timing. For example, after the stop operation is detected so that the combination of symbols related to the internal winning combination is displayed when the internal winning combination related to winning is determined as a result of lottery using random numbers, The rotation of the reel continues within a predetermined period (for example, 190 msec), and then stops.

In recent years, in such a spinning machine, a combination of symbols associated with a relatively large number of medals etc. is associated with a combination of symbols associated with a relatively small number of medals. A pull-in priority table with a higher priority than the combination is provided, and the control unit stops the rotation of the reels based on the priority defined in the pull-in priority table, thereby reducing the number of medals and the like. Even in a state where a combination of symbols associated with the number of payouts can be displayed, a combination of symbols associated with a number of payouts such as more medals has been proposed (for example, Patent Document 1).
JP-A-11-299965

  However, in the above-described conventional gaming machine, when a plurality of symbol combinations can be displayed, when the number of payouts such as medals associated with each symbol combination is equal, between these symbol combinations Therefore, there is no way to determine which combination of symbols is preferentially displayed, and there is a problem that the position at which the rotation of the reel is stopped is arbitrarily determined.

  In addition, in the above conventional gaming machine, if the position where the rotation of the reels is stopped is determined so that only one combination of symbols is displayed before the remaining rotating reel becomes one, The possibility that a combination of other symbols is displayed was excluded, and there was a possibility that the player suffered a disadvantage.

  In view of the above, an object of the present invention is to provide a swivel-type gaming machine that can more appropriately reflect the profit to be obtained by the player in determining the position where the rotation of the reel is stopped.

  In order to achieve the above object, the present invention provides the following spinning machine.

According to the first aspect of the present invention, the spinning cylinder type gaming machine includes a plurality of reels (for example, reels 3L, 3C, and 3R described later) each having a plurality of symbols arranged on each surface, and a start operation detection that detects a start operation. Internal winning combination determination that determines an internal winning combination based on means (for example, a start switch 6S described later, a CPU 31 described later, and a medal insertion / start check process described later) and detection of a start operation performed by the start operation detecting means. Means (for example, CPU 31 described later, internal lottery processing described later) and reel rotating means for rotating each of the plurality of reels (for example, stepping motors 49L, 49C, 49R described later, CPU 31 described later, reel control described later) Processing), stop operation detecting means (for example, a stop switch 7S described later) for detecting stop operation according to the types of the plurality of reels, A position specifying means (for example, a symbol counter described later) for specifying the position in the rotation direction of the game according to the type of the reel, and a position that can be specified by the position specifying means are displayed to the player. Based on the prediction means (for example, CPU 31 described later, display combination search processing described later) for predicting the amount of profit given to the player based on the combination of symbols, and the position that can be specified by the position specifying means, A winning number calculation means for calculating the number of predetermined symbol combinations displayed to the player (for example, a CPU 31 described later, a CB operating process described later), and the profit expected by the prediction means. Priority is given according to the position that can be specified by the position specifying means based on the number and the number of the predetermined symbol combinations calculated by the winning number calculating means. When a stop operation is detected by priority order determining means (for example, a CPU 31 described later, CB operating process described later) and the stop operation detecting means, the position specifying means determines in advance from the position specified by the position specifying means. Reel stop means (for example, a CPU 31 described later, a reel described later) for stopping the rotation of the corresponding reel based on the position where the symbol with the highest priority determined is arranged among the positions in the determined range. Stop control processing) and the reel stop means stop the rotation of each of the plurality of reels, and when a predetermined symbol combination is displayed to the player, a lot of profits are given to the player. Profit determining means (e.g., CPU 31 described later, display combination search processing described later), and the priority is a bit string composed of a plurality of bits, The plurality of bits corresponds to the amount of profit expected by the prediction means, and the plurality of lower bits correspond to the number of the predetermined symbol combinations calculated by the winning number calculation means. (For example, a display combination expected storage area (game state CB: game state), which will be described later, FIG. 21 (2)) .

  According to said structure, according to the position which can be pinpointed by a position specific | specification means, the amount of the profit estimated based on the combination of the symbol displayed with respect to a player, and the player displayed beforehand The priority order is determined based on the predetermined number of symbol combinations, and when the stop operation is detected, the position of the position specified by the position specifying unit is the most in each position within a predetermined range. The rotation of the corresponding reel is stopped based on the position where the symbol for which the high priority is determined is arranged.

  That is, in addition to the amount of profits given to the player, the position where the reel rotation is stopped is determined by referring to the number of symbol combinations related to the granting of profits that can be displayed to the player. Therefore, when a combination of a plurality of symbols can be displayed, even if the number of paid-out medals and the like associated with each other is the same, the position where the number that can be displayed is larger is set as an appropriate position. The rotation can be stopped. In addition, since only one of the symbol combinations is displayed (especially before the remaining spinning reel becomes one), the possibility that another symbol combination is displayed is excluded. It is also possible to prevent this, and it is possible to more appropriately reflect the profit to be obtained by the player in determining the position where the rotation of the reel is stopped.

According to a second aspect of the present invention, the spinning machine is a random value extraction unit that extracts a random value based on detection of a start operation performed by the start operation detection unit (for example, a CPU 31 described later, a reset interrupt process described later). ), And an internal lottery table storage unit (for example, ROM 32 to be described later) for storing an internal lottery table that defines a range of numerical values to which the random number value that can be extracted by the random number extraction unit belongs according to the type of the internal winning combination, The internal winning combination determining means determines a plurality of types of internal winning combinations related to the predetermined symbol combination irrespective of the random number value extracted by the random number value extracting means , and the priority order determining means Rotates a value representing the amount of profit expected by the prediction means for the plurality of lower-order bits, the rotated value, and the winning number calculation means The priority order is determined by logically summing the value representing the number of predetermined symbol combinations to be issued (for example, CPU 31 described later, CB operating processing described later) and specified by the position specifying means Depending on the position in the rotation direction of the reel, a symbol arrangement table in which a symbol type according to the symbol type arranged at the position and a symbol code according to the reel type to which the symbol is arranged is defined (for example, left described later) , Middle and right reel symbol arrangement tables, FIGS. 5 to 7), and the symbol code is defined so that the corresponding symbol constitutes which of the predetermined symbol combinations can be identified, The predetermined symbol combinations include a combination of symbols composed only of symbols of the same symbol type, and a combination of symbols composed of a plurality of types of symbols. , Special Even if the symbol type is the same, the symbol code can be used to identify which of the predetermined symbol combinations is configured according to the type of reel on which the symbol is arranged. It is characterized by being prescribed .

  According to the configuration described above, a plurality of types of internal winning combinations related to a predetermined symbol combination are determined regardless of the random number value extracted by the random number extraction means. It is possible to allow display of a combination of symbols.

  According to the rotating type gaming machine of the present invention, the expected amount of profit based on the combination of symbols displayed to the player according to the position in the rotation direction of the reel, and the display to the player Since the position where the rotation of the reel is stopped is determined based on the predetermined number of symbol combinations, the player should obtain more profits in determining the position where the rotation of the reel is stopped. It is possible to reflect appropriately.

FIG. 5 shows a symbol arrangement table for the left reel. FIG. 6 shows a middle reel symbol arrangement table. FIG. 7 shows a symbol arrangement table for the right reel.

  In the symbol arrangement table, according to the position in the rotation direction of the reel, which can be specified by the symbol counter, data according to the type of the symbol arranged at the position and the type of the reel on which the symbol is arranged are defined. . More specifically, symbol positions “0” to “20” corresponding to the symbol counter described above and symbol codes corresponding to symbols arranged at the symbol positions are defined. The symbol code specified for each of the symbols arranged on the surface of the reel is not only the symbol type but also the role that the symbol plays according to the type of reel to be arranged, in other words, the reel to be arranged. It is also set according to the type of symbol combination that the symbol constitutes according to the type. In other words, the symbol code is data for identifying which of a plurality of predetermined symbol combinations each symbol arranged on the surface of each of the plurality of reels constitutes.

  In the present invention, when a symbol is specified for each reel among a plurality of symbols arranged on the surface of each of a plurality of reels, the specified symbol combination is a predetermined symbol combination. Are given to the player with benefits (privileges such as winnings and actions).

  For example, the symbol “red 7” arranged on the surface of the left reel 3L is obtained by combining a predetermined symbol combination “red 7-red 7-red 7” and “red 7-red 7-blue 7” in advance. And a predetermined combination of symbols. On the other hand, the symbol “red 7” arranged on the surface of the middle reel 3C has a predetermined symbol combination “red 7-red 7-red 7” and “red 7-red 7-blue 7”. ”And a predetermined symbol combination“ Cherry-ANY-ANY ”. Furthermore, the symbol “red 7” arranged on the surface of the right reel 3R is a predetermined combination of symbols “red 7-red 7-red 7” and a predetermined symbol “cherry-ANY-ANY”. A combination of symbols.

  From the above, even for the same symbol of “red 7”, it is arranged on the surface of the left reel 3L, the one arranged on the surface of the middle reel 3C, and the surface of the right reel 3R. The role is different. Therefore, in the present invention, even for the same symbol of “red 7”, data for identifying a predetermined symbol combination constituted by the reel type is set as a symbol code.

  The symbol code is 1-byte data. The lowest bit 0 is cherry, followed by bit 1 is bell, bit 2 is watermelon, bit 3 is replay, bit 4 is RB, and bit 5 is CB. It corresponds. For this reason, the symbol “red 7” arranged on the surface of the left reel 3L is a symbol constituting a symbol combination related to RB and a symbol combination related to CB. And “00110000B (030H)” in which bit 5 is turned on is defined.

  The most significant bit 7 corresponds to “display confirmation” indicating that the display combination is confirmed. For example, if the cherry of the left reel 3L is displayed on any of the upper, middle, and lower tiers of the left display window 4L, the display combination cherry is determined regardless of the symbol type of the other reels 3C and 3R. Therefore, for the cherry that is the symbol at symbol position 0 and symbol position 12 of the left reel 3L, “10000001B (081H)” in which bit 0 corresponding to cherry and bit 7 corresponding to display confirmation are turned on is defined as the symbol code. Has been. By giving the bit 7 the role of “display confirmation”, it is not necessary to turn on the bit 0 corresponding to the cherry for the symbol code of each symbol arranged on the surface of the middle reel 3C and the right reel 3R.

  Next, an internal lottery table determination table stored in the ROM 32 will be described with reference to FIG.

  In the internal lottery table determination table, the type of the internal lottery table and the number of lotteries determined in accordance with the gaming state are defined. In the general gaming state, the internal lottery table for the general gaming state is determined, and basically the number of lotteries is determined to be 6. In the CB gaming state described later, an internal lottery table for general gaming state is determined, and the number of lotteries is determined to be 3. In the RB gaming state described later, the internal lottery table for the RB gaming state is determined, and the number of lotteries is determined to be 3.

  Next, the internal lottery table stored in the ROM 32 will be described with reference to FIG.

  In the internal lottery table, a lower limit value and an upper limit value of random numbers assigned according to each winning number (that is, a range of numerical values that are greater than or equal to the lower limit value and less than or equal to the upper limit value) are defined. The winning number is data for identifying a range of a plurality of numerical values defined in the internal lottery table, and is data used when determining an internal winning combination to be described later.

  In the internal lottery table, it is determined whether or not the random number value extracted from the range of “0 to 65535” belongs to the numerical range of each winning number. The aforementioned number of lotteries indicates the number of times this determination is performed. As a result of the determination for the number of times of lottery, when it is stored in the random value storage area but belongs to any numerical value range, the corresponding winning number is determined. If the extracted random number value does not belong to any numerical value range, the winning number is determined to be 0. In addition, the winning probability of each winning number is “the number obtained by adding 1 to the difference between the upper limit value and the lower limit value specified for each winning number (that is, the size of the numerical range and equal to the width in the figure). / Number of all random values that can be extracted (ie 65536).

  (1) of FIG. 9 shows the internal lottery table for a general gaming state. In the general game state internal lottery table, a lower limit value and an upper limit value corresponding to the winning numbers 1 to 6 are defined for each inserted number (ie, 1 to 3). As the number of inserted coins increases, the winning probabilities of winning numbers (that is, winning numbers 1 to 3) for paying out medals, which will be described later, and winning numbers (ie, winning numbers 5 and 6) related to the operation of the bonus game are increased. It is high.

  (2) of FIG. 9 shows the internal lottery table for RB gaming state. In the RB gaming state internal lottery table, a lower limit value and an upper limit value corresponding to the winning numbers 1 to 3 are defined. The RB gaming state internal lottery table has a configuration in which the winning probability of the winning number 2 (bell described later) is extremely higher than that of the general gaming state internal lottery table.

  Next, the internal winning combination determination table stored in the ROM 32 will be described with reference to FIG.

  In the internal winning combination determination table, 1-byte flag data is defined according to each of the aforementioned winning numbers. The data is obtained as a result of an internal lottery based on a random number value. In the present embodiment, the data is referred to as an “internal winning combination” for convenience of explanation (and in this embodiment, Each internal winning combination is distinguished by the name shown in the “Content” section of the figure). Specifically, according to each of the winning numbers 0 to 6, winning, cherry, bell, watermelon, replay, RB, and CB are defined as internal winning combinations. The content of data defined as an internal winning combination is basically the same as the content of the above-described symbol code (for example, bit 0 corresponds to cherry). The data indicating the aforementioned display combination is also 1-byte data, and the content is the same as the content of the internal winning combination.

  Next, the stop table determination table stored in the ROM 32 will be described with reference to FIG.

  In the stop table determination table, the type of stop table corresponding to each winning number (that is, winning number 0 to winning number 6) stored in the winning number storage area is defined for each gaming state. Specifically, in the general gaming state and the RB gaming state, according to each of the winning number 0 to the winning number 6, the stop for lose, cherry, bell, watermelon, replay, RB, and CB, respectively. A table is defined. In the CB gaming state, the CB operating stop table is shared regardless of the type of the winning number stored in the winning number storage area.

  Next, the bell stop table stored in the ROM 32 will be described with reference to FIG.

  In the stop table, the symbol position corresponding to the symbol counter of the corresponding reel when the stop operation is detected by the stop switch 7S (that is, the symbol position at which the rotation of the reel starts to be stopped is indicated by “stop start position”. The number of sliding pieces according to “)” is specified. The number of sliding pieces is the amount of rotation of the reel from when the stop operation is detected by the stop switch 7S until the rotation of the corresponding reel stops. In other words, the number of symbols passing through the middle of the corresponding display window in the period from when the stop operation is detected by the stop switch 7S until the rotation of the corresponding reel stops. This is grasped by the value of the symbol counter updated after the stop operation is detected by the stop switch 7S.

  In the present embodiment, basically, after the signal is output by the stop switch 7S, the control of stopping the rotation of the reels 3L, 3C, 3R is performed within 190 msec, and the numerical value range “0” to “4” is controlled. One of them is determined as the number of sliding pieces. For example, if the stop start position is “0” and the determined number of sliding symbols is “4”, rotation of the corresponding reel so that the symbol at the symbol position “4” is displayed in the middle of the corresponding display window. Can be stopped. In this way, the reel rotation stop control that allows the symbols within the range of the number of sliding pieces from the stop start position to be displayed on the center line 8b is called “retraction”. In addition, the symbol position where the number of sliding pieces is drawn from the stop start position and stopped is referred to as “scheduled stop position”. That is, the symbol position obtained by adding the number of sliding pieces to the stop start position is the planned stop position.

  FIG. 12 shows a CB operating stop table. In the CB gaming state, at least one of the three reels 3L, 3C, 3R (in this embodiment, only the left reel 3L is applied), within 75 msec after the signal is output by the stop switch 7S Control to stop the rotation is performed, and either “0” or “1” is determined as the number of sliding pieces. As for the other reels (in this embodiment, the middle reel 3C and the right reel 3R are applied) other than the reel whose maximum number of sliding pieces is defined as “1”, the numerical range is the same as in the general gaming state. Any one of “0” to “4” is determined as the number of sliding symbols.

  Here, the number of symbols on each of the reels 3L, 3C, 3R displayed by the display windows 4L, 4C, 4R is X (X is a natural number, and in the present embodiment, “3” in the upper, middle, and lower stages). Assuming that the maximum value of the number of sliding symbols is Y (Y is a natural number and “4” except for the left reel 3L in the MB gaming state in this embodiment), the replay symbol and the bell symbol are On the surface of 3L, 3C, 3R, at intervals where Y + 1 other symbols do not continue (in other words, for example, the number of other symbols arranged between replays is 0 or more and Y or less). Arranged. Basically, a combination of symbols made up of such symbols is determined by the player regardless of the timing, etc., if the player performs a stop operation on condition that the corresponding internal winning combination is determined. Will be displayed to the user. In other words, on the surface of each of the reels 3L, 3C, 3R, there are Y + 1 consecutive symbols on the surface (in other words, for example, the number of other symbols arranged between replays is Y + 1 or more). In order for a combination of symbols composed of symbols to be displayed to be displayed to the player, the player is required to perform a stop operation at an appropriate timing, and skill regarding the stop operation is required. Is done.

  Next, the search order table stored in the ROM 32 will be described with reference to FIG.

  The search order table searches for applicable numerical values from numerical values in a predetermined range as the number of sliding symbols (that is, 0 or 1 only for the left reel 3L in the CB gaming state, and 0 to 4 otherwise). The search order is defined, and the search order indicates the order. The search order table of the present embodiment defines the search order based on the number of sliding symbols extracted from the stop table. For example, when the number of sliding pieces extracted from the stop table is “0”, the number of sliding pieces “0” as the search order 1, the number of sliding pieces “2” as the search order 2, and the sliding piece as the search order 3 The number “4”, the number of sliding pieces “1” as the search order 4, and the number of sliding pieces “3” as the search order 5 are defined.

  In the search order table, the search order is defined so that the number of sliding symbols extracted from the stop table is the highest, so the number of sliding symbols extracted from the stop table is higher than the number of other sliding symbols. The priority is decided. Therefore, it is possible to prioritize the display of the symbols intended when developing the stop table.

  Next, with reference to FIG. 14, the priority pull-in order table stored in the ROM 32 will be described.

  The priority pull-in order table defines pull-in data according to predetermined priorities (that is, priority order 1 to priority order 3). The priority order defines the order in which the drawing is preferentially performed between the types of predetermined symbol combinations related to the provision of profit (or between the types of the internal winning combination). The pull-in data is 1-byte flag data, and has the same contents as the internal winning combination and the symbol code. For example, the priority 3 defines cherry, bell, and watermelon, and the pull-in data is represented by “00000111B” in which the corresponding bit 0 to bit 2 are turned on.

  Next, the payout number table stored in the ROM 32 will be described with reference to FIG.

  In the payout number table, the payout number corresponding to the display combination (that is, cherry, bell, and watermelon) related to the payout of medals for each inserted number (that is, the inserted number 1, the inserted number 2, and the inserted number 3). (It is the aforementioned payout table that displays this content to the player). In the payout number table, for example, “1” is displayed for cherry (00000001B), “2” is displayed for bell (00000010B), and “3” is displayed for watermelon (00000100B). A numerical value in which each corresponding bit is numbered is defined.

  Next, the bonus operation time table stored in the ROM 32 will be described with reference to FIG.

  The bonus operation time table defines data stored in a predetermined storage area of the RAM 33 when the operation of the bonus game is started. Specifically, when the RB operation is started, the RB operating flag is turned on, 12 is stored in the possible game number counter, and 8 is stored in the possible winning number counter. The game possible number counter is data for counting the number of unit games performed during the RB operation. The winning possible number counter is data for counting the number of times that the display combination related to the payout of medals is determined during the RB operation (that is, the number of times that winning is determined). When the operation of CB is started, the CB operation flag is turned on, and 100 is stored in the bonus end number counter. The bonus end number counter is data for counting the total number of payouts during the operation of the CB.

  Next, the symbol storing offset data table stored in the ROM 32 will be described with reference to FIG.

  In the symbol storage offset data table, offset data corresponding to five addresses (which correspond to the number of valid lines) is defined for each type of reel 3L, 3C, 3R. The offset data is a value representing the position of a certain data by a difference (distance) from a reference point. In this embodiment, the address of a symbol code (from the symbol arrangement table (based on the reference address) ( That is, the symbol position) is calculated. For example, when the reference address is “20” and “1” is acquired as the offset data, “1” is added to the reference address “20”, and “0” is calculated.

  Next, the configuration of the internal winning combination storing area of the RAM 33 will be described with reference to FIG. The configuration of the internal winning combination storage area for storing the internal winning combination and the configuration of the display combination storing area for storing the display winning combination are the same.

  When 1-byte flag data is acquired as the internal symbol combination (or display combination), the flag data is stored in the internal symbol combination storage area (or display combination storage area) of the RAM 33. Bits 0 to 5 of the storage area correspond to cherry, bell, watermelon, replay, RB, and CB, respectively (bits 6 and 7 are not used). When all the bits in the storage area are 0, the internal winning combination (or display combination) is lost.

  Next, the configuration of the carryover combination storage area of the RAM 33 will be described with reference to FIG.

  When an internal winning combination relating to the operation of the bonus game is determined by the internal lottery process, an identifier (that is, flag data) indicating it is stored in this carryover combination storing area. Specifically, bit 0 corresponds to RB, and bit 1 corresponds to CB. The identifier stored in the carryover combination storage area is cleared when the bonus game is started. In other words, when an internal winning combination related to the operation of the bonus game is determined, the identifier is stored until the operation of the bonus game is started (so-called “carryover”). The stored identifier is called “carryover combination”). While the identifier is stored in the carryover combination storage area, the stored identifier is determined as the internal winning combination regardless of the extracted random number value. In addition, since the carryover combination is determined based on the internal winning combination, it can be said to be a subordinate concept of the internal winning combination.

  Next, the configuration of the symbol storage area of the RAM 33 of the main control circuit 71 will be described with reference to FIG.

  In the symbol storage area, symbol codes related to symbols of the reels 3L, 3C, 3R displayed along the effective lines in the display window are stored. More specifically, in the present embodiment, five types of effective lines are provided: a center line 8c, a top line 8b, a bottom line 8d, a cross-down line 8e, and a cross-up line 8a. The symbol code of the symbol of each reel displayed on is stored. For example, in the case of the center line 8c, the symbol code of the symbol of each reel located in the middle stage in each display window 4L, 4C, 4R is stored. FIG. 20 shows an example of storage when the symbol position of each reel 3L, 3C, 3R is “5”.

  Next, the configuration of the expected display combination storing area of the RAM 33 of the main control circuit 71 will be described with reference to FIG.

  In the expected display combination storing area, the priority pull-in status determined in accordance with the symbols at the symbol positions “0” to “20” of the rotating reel is stored. (1) of FIG. 21 shows the contents of data stored in the expected display combination storing area in the general gaming state. (2) of FIG. 21 shows the contents of data stored in the expected display combination storing area in the CB gaming state.

  In the general gaming state, the priority draw-in status is “005H (00000101B)” for replay, “003H” for RB and CB, “002H” for cherry, bell, and watermelon, “001H” can be stopped, and “000H”. Is stipulated as a suspension prohibition.

  In the CB gaming state, in the priority pull-in status, the upper 5 bits of bit 3 to bit 7 correspond to the payout number (for example, “01111” if the payout number is “15”), bit 0 to bit 2 The lower 3 bits correspond to the number of symbol combinations related to medal payout (hereinafter, the number of winning prizes). Further, “001H” is defined as being able to be stopped, and “000H” is defined as being prohibited from being stopped.

  The priority pull-in status has a higher priority as the value is larger. By referring to the priority pull-in status, it is possible to relatively evaluate the priority among the symbols arranged on the surface of the reel. Further, the symbol for which the highest value is determined as the priority pull-in status is the symbol with the highest priority. In other words, the priority pull-in status can be said to indicate the order between the symbols arranged on the surface of the reel. As described later, in the general gaming state, it is influenced by the internal winning combination determined using random numbers. On the other hand, in the CB gaming state, it is determined by being influenced by the payout number and the winning number. In this embodiment, the priority pull-in status is configured such that the higher the data value, the higher the priority is. However, the priority pull-in status is not limited to this. Is possible.

  Next, a correspondence table between reels and expected display combination storage areas will be described with reference to FIG.

  The expected display combination storage area is determined by the number of display combination expected storage areas to be used in accordance with the number of rotating reels (that is, three). It is associated. For example, if all three reels are rotating, the expected display combination storage area 1 corresponds to the left reel 3L, the expected display combination storage area 2 corresponds to the middle reel 3C, and the expected display combination storage area 3 Corresponds to the right reel 3R. Further, when the two reels are rotating, the expected display combination storing area 1 corresponds to one of the left side, and the expected display combination storing area 2 corresponds to the other. If one reel is rotating, the expected display combination storing area 1 corresponds to this reel.

  Next, the control performed by the CPU 31 of the main control circuit 71 will be described with reference to the flowcharts shown in FIGS.

  First, a reset interrupt process performed by the CPU 31 of the main control circuit 71 will be described with reference to FIG. The CPU 31 turns on the power and applies a voltage to the reset terminal to generate a reset interrupt, and sequentially performs the reset interrupt processing stored in the ROM 32 based on the occurrence of the reset interrupt. It is configured.

  When the power is turned on, first, the CPU 31 performs an initialization process (step S1). In this process, a process of restoring the register data and execution address stored in the RAM 33 when the power is shut off is performed. Next, the CPU 31 clears the designated storage area in the RAM 33 (step S2). In this process, data stored in various storage areas of the RAM 33 is cleared.

  Next, the CPU 31 performs a medal acceptance / start check process which will be described later with reference to FIG. 24 (step S3). In this process, the insertion number counter and the like are updated based on the input check of the medal sensor 22S and the bet switches 11S, 12S, and 13S, and the input of the start switch 6S is checked. Next, the CPU 31 extracts a random value and stores it in the random value storage area (step S4).

  Next, the CPU 31 performs a gaming state monitoring process (step S5). Specifically, if the RB operating flag is on, an identifier (so-called flag) indicating the RB gaming state is stored in the RAM 33, and if the CB operating flag is on, the identifier indicating the CB gaming state is stored in the RAM 33. If both the RB operating flag and the CB operating flag are off, an identifier indicating the general gaming state is stored in the RAM 33. Next, the CPU 31 performs an internal lottery process which will be described later with reference to FIG. 25 (step S6). In this process, a determination is made as to which of a plurality of numerical ranges defined in the internal lottery table the random value stored in the random value storage area belongs to determine the internal winning combination.

  Next, the CPU 31 performs a reel stop initial setting process which will be described later with reference to FIG. 26 (step S7). In this processing, processing such as determination of a stop table based on the winning number storage area and determination of priority drawing status for each symbol arranged on the surface of each reel 3L, 3C, 3R is performed. Next, the CPU 31 transmits a start command to the sub control circuit 72 (step S8). The start command includes data such as an internal winning combination and a gaming state. Next, the CPU 31 requests the start of rotation of all reels (step S9). When the start of rotation of all reels is requested, processing for starting rotation of the reels is performed in an interrupt process (see FIG. 36) described later. The RAM 33 stores data indicating the type of stop button that accepts a pressing operation by the player as valid.

  Next, the CPU 31 performs a reel stop control process which will be described later with reference to FIG. 32 (step S10). In this process, a process for stopping the rotation of all the reels 3L, 3C, 3R is performed. Next, the CPU 31 performs a display combination search process which will be described later with reference to FIG. 29 (step S11). In this display combination search process, as a result of the rotation of all the reels 3L, 3C, 3R being stopped, the combination of symbols displayed along the effective lines 8a to 8e is specified based on the symbol storage area, and the display combination is determined. The payout number is determined, and the process of determining the profit given to the player is performed.

  Next, the CPU 31 transmits a display combination command to the sub control circuit 72 (step S12). The display combination command includes data such as the determined display combination. Next, the CPU 31 performs medal payout processing (step S13). In this process, the hopper 40 is controlled and the credit counter is updated based on the payout number counter. Next, the CPU 31 updates the bonus end number counter based on the payout number (step S14). In this process, on the condition that the bonus end number counter is 1 or more, a value corresponding to the payout number is subtracted from the counter.

  Next, the CPU 31 determines whether or not the RB operating flag or the CB operating flag is on (step S15). When determining that the RB operating flag or the CB operating flag is on, the CPU 31 performs a bonus end check process described later with reference to FIG. 35 (step S16). In this process, a process for terminating the operation of the bonus game is performed on the basis of whether or not various counters stored in the RAM 33 are updated to 0 when the bonus game is operated. The CPU 31 performs a bonus operation check process which will be described later with reference to FIG. 34 after step S16 or when it is determined in step S15 that neither the RB operating flag or the CB operating flag is on. This is performed (step S17). When this process ends, the process proceeds to step S2.

  Next, with reference to FIG. 24, the medal acceptance / start check process will be described.

  First, the CPU 31 determines whether or not a medal has passed (step S51). Specifically, when the inserted medal sensor 22S is switched from on to off, it is determined that a medal has passed. When determining that the medal has passed, the CPU 31 determines whether or not the insertion number counter is the maximum value (step S52). The maximum value is defined as “1” when the RB operation flag is on or the CB operation flag is on, and “3” when the RB operation flag and the CB operation flag are off. When determining that the insertion number counter is not the maximum value, the CPU 31 adds 1 to the insertion number counter (step S53). Next, the CPU 31 stores 5 in the effective line counter (step S54). The valid line counter is data for specifying the number of valid lines. Next, the CPU 31 transmits a medal insertion command to the sub control circuit 72 (step S55). The medal insertion command includes data on the number of inserted coins.

  Before step S51, if the automatic insertion counter (the value of the insertion number counter at that time is copied to the counter when the replay is determined as a display combination) is not 0, the automatic insertion counter is turned on. Automatic loading processing for copying to the loading number counter is performed. Further, in order to prevent the inserted number counter from being added even if medals are inserted from the medal insertion slot 22, the selector ( The solenoid (not shown) is not driven.

  When the CPU 31 determines in step S52 that the inserted number counter is the maximum value, the CPU 31 adds 1 to the credit counter (step S56). The credit counter is data for counting the number of medals to be credited. Next, the CPU 31 checks the bet switch after step S56, after step S55, or when it is determined in step S51 that no medal has passed (step S57). Specifically, when the bet switches 11S, 12S, and 13S are on, the type is specified, and the value to be added to the inserted number counter based on the maximum values of the inserted number counter, the credit counter, and the inserted number counter. Is calculated and the insertion number counter is updated. The check of the bet switch is not performed while a medal passes or when a medal passes.

  Next, the CPU 31 determines whether or not the insertion number counter is 0 (step S58). If the CPU 31 determines that the insertion number counter is 0, it proceeds to step S51. When determining that the insertion number counter is not 0, the CPU 31 determines whether or not the start switch 6S is on (step S59). When the CPU 31 determines that the start switch 6S is not on, the CPU 31 proceeds to step S51. When determining that the start switch 6S is on, the CPU 31 ends the medal acceptance / start check process.

  Next, an internal lottery process will be described with reference to FIG.

  First, the CPU 31 determines the type of the internal lottery table and the number of lotteries based on the gaming state and the internal lottery table determination table (step S91). Next, the CPU 31 determines whether or not data indicating RB or CB is stored in the carryover combination storage area (step S92). When it is determined that the data indicating RB or CB is stored in the carryover combination storage area, the CPU 31 changes the number of lotteries to 4 (step S93). With this process, when there is a carryover combination, RB or CB is not determined redundantly. After determining that the data indicating RB or CB is not stored in the carryover combination storage area after step S93 or at step S92, the CPU 31 sets the same value as the number of lotteries as the winning number (step S94).

  Next, the CPU 31 compares the random number value stored in the random number value storage area with the lower limit value and the upper limit value corresponding to the inserted number counter and the winning number set (step S95). Next, the CPU 31 determines whether or not the random number value is not less than the lower limit value and not more than the upper limit value (step S96). When determining that the random number value is not less than the lower limit value and not more than the upper limit value in step S96, the CPU 31 refers to the internal winning combination determination table and determines the internal winning combination based on the winning number (step S97). Next, the CPU 31 stores (overwrites) the set winning number in the winning number storage area (step S98).

  Next, the CPU 31 determines whether or not the internal winning combination is RB or CB (step S99). When determining that the internal winning combination is RB or CB, the CPU 31 stores data indicating RB or CB in the carryover combination storing area (step S100). After step S100 or when it is determined in step S99 that the internal winning combination is not RB or CB, the CPU 31 stores the logical sum of the internal winning combination and the carryover combination storing area in the internal winning combination storing area (step S101). ). After step S101 or when it is determined in step S96 that the random number value is not less than the lower limit value and not less than the upper limit value, the CPU 31 subtracts 1 from the number of lotteries (step S102). Next, the CPU 31 determines whether or not the number of lotteries is 0 (step S103). When the CPU 31 determines that the number of lotteries is not 0, the CPU 31 proceeds to step S94.

  When determining that the number of lotteries is 0 in step S103, the CPU 31 stores the logical sum of the internal winning combination storing area and the carryover combination storing area in the internal winning combination storing area (step S104). Next, the CPU 31 determines whether or not it is in the CB gaming state (step S105). When the CPU 31 determines that it is not in the CB gaming state, it ends the internal lottery process. When determining that the game state is the CB gaming state, the CPU 31 turns on all the bits 0 to 2 of the internal winning combination storing area (step S106). That is, in the CB gaming state, regardless of the determined winning number type (that is, regardless of the extracted random number value), all the bits relating to the payout (winning) of medals are turned on. It is possible to display any combination of symbols related to the payout on the active line. When this process ends, the internal lottery process ends.

  Next, the reel stop initial setting process will be described with reference to FIG.

  First, the CPU 31 refers to the stop table determination table and determines a stop table based on the gaming state and the winning number storage area (step S121). In this process, if the winning number storage area is 0 and the carryover combination storage area is not 0, the carryover combination storage area is numbered (5 is stored for RB, and 6 is stored for CB). A stop table is determined based on the number. Next, the CPU 31 stores the rotating identifier (0FFH) in each area of the symbol storage area (step S122). Next, the CPU 31 performs the expected display combination storing process described later with reference to FIG. 27 (step S123). In this process, a process of determining a priority pull-in status according to each symbol “0” to “20” arranged on the surface of each reel 3L, 3C, 3R is performed. When this process ends, the reel stop initial setting process ends.

  Next, the expected display combination storing process will be described with reference to FIG.

  First, the CPU 31 stores the number of stop buttons for which the pressing operation is valid as the number of display combination searches (step S131). For example, if called from the reel stop initial setting process described above, 3 is stored as the number of display combination searches. Next, the CPU 31 sets the start address of the expected display combination storing area (step S132). Specifically, the address of the symbol position “0” in the expected display combination storing area 1 is set.

  Next, the CPU 31 sets “0” as the symbol position data and sets “21” as the number of checks (step S133). Next, the CPU 31 determines a reel corresponding to the number of display combination searches from the right among the rotating reels as a search target reel (step S134). Specifically, all of the rotating reels are searched, and are determined as search target reels in the order of the left reel 3L, the middle reel 3C, and the right reel 3R. If called from the reel stop initial setting process, all reels are pseudo-rotating (0FFH), and the display combination search count is 3, so the left reel 3L is determined first.

  Next, the CPU 31 stores “000H” in the stop check status storage area (step S135). Next, the CPU 31 performs a symbol code storing process which will be described later with reference to FIG. 28 (step S136). In this process, the symbol code of the symbol located on each effective line is stored in the symbol storage area based on the reel to be searched and the symbol arrangement table. Next, the CPU 31 performs a display combination search process which will be described later with reference to FIG. 29 (step S137). In this process, a process of storing a display combination that may be determined in the display combination storage area is performed based on the symbol storage area.

  Next, the CPU 31 performs a priority pull-in status acquisition process which will be described later with reference to FIG. 30 (step S138). In this process, a process for determining the priority pull-in status is performed based on the display combination storing area. Next, the CPU 31 stores the priority pull-in status at the current address in the expected display combination storing area (step S139). Next, the CPU 31 adds 1 to the address of the expected display combination storing area (step S140). Next, the CPU 31 adds 1 to the symbol position data and subtracts 1 from the number of checks (step S141).

  Next, the CPU 31 determines whether or not the number of checks is 0 (step S142). If the CPU 31 determines that the number of checks is not 0, it proceeds to step S134. On the other hand, when the CPU 31 determines that the number of checks is 0, the CPU 31 subtracts 1 from the number of display combination searches (step S143). Note that after the second stop, the number of display combination searches is zero. Next, the CPU 31 determines whether or not the number of display combination searches is 0 (step S144). When the CPU 31 determines that the number of display combination searches is 0, the CPU 30 ends the expected display combination storing process.

  If the CPU 31 determines in step S144 that the number of display combination searches is not 0, it stores the rotating identifier (0FFH) in all symbol storage areas (step S145). Next, the CPU 31 determines whether or not the number of stop buttons for which the pressing operation is valid is 3 (step S146). When the CPU 31 determines that the number of stop buttons for which the pressing operation is valid is 3, the CPU 31 proceeds to step S133.

  If the CPU 31 determines in step S146 that the number of stop buttons to which the pressing operation is effective is not 3, the reel corresponding to the pressed button is determined as a search target reel (step S147). Next, the CPU 31 acquires the scheduled stop position as the symbol position data (step S148). Next, the CPU 31 stores “080H” in the stop check status storage area (step S149). Next, the CPU 31 performs a symbol code storing process which will be described later with reference to FIG. 28 (step S150). When this process ends, the process moves to step S133.

  Next, the symbol code storing process will be described with reference to FIG.

  First, the CPU 31 sets the top address of the symbol arrangement table corresponding to the search target reel (step S161). Specifically, the address of the top symbol position “20” in the symbol arrangement table is set. Next, the CPU 31 adds the symbol position data to the current address of the symbol arrangement table and stores it as a reference address (step S162). Next, the CPU 31 sets the head address of the symbol storage offset table corresponding to the search target reel (step S163). Next, the CPU 31 sets the top address of the symbol storage area set based on the reel to be searched, and obtains an effective line counter (ie, 5) (step S164).

  Next, the CPU 31 acquires an address stored in the reference address storage area (step S165). Next, the CPU 31 adds the offset data stored at the current address in the symbol storing offset data table to the reference address (step S166). Next, the CPU 31 acquires the symbol code stored at the current address (that is, the address obtained by adding the offset data to the reference address) in the symbol arrangement table (step S167). Next, the CPU 31 stores the logical sum of the symbol code and the stop check status storage area in the symbol storage area (step S168).

  Next, the CPU 31 subtracts 1 from the valid line counter and adds 1 to the address of the symbol storing offset data table (step S169). For example, if the left reel 3L is a search target, the addresses are updated in the order of “1 → 2 → 0 → 2 → 0”. Next, the CPU 31 adds 3 to the address of the symbol storage area (step S170). That is, the addresses are updated in the order of “center line → top line → bottom line → cross down line → cross up line”. Next, the CPU 31 determines whether or not the valid line counter is 0 (step S171). When the effective line counter is not 0, the CPU 31 proceeds to step S165, and when the effective line counter is 0, the symbol code storing process is terminated.

  Next, the display combination search process will be described with reference to FIG.

  First, the CPU 31 clears the display combination storing area (step S181). Next, the CPU 31 sets the top address of the symbol storage area and acquires an effective line counter (step S182). Specifically, the address of the center line 8c is set, and 5 is transferred from the RAM 33 to the register as an effective line counter. Next, the CPU 31 sets 3 as the number of reel checks (step S183). Next, the CPU 31 sets “0FFH” as display check data (step S184).

  Next, the CPU 31 performs a logical product of the display check data and the symbol storage area (step S185). That is, for each valid line, the logical product of each symbol code acquired according to the type of the plurality of reels is taken. Next, the CPU 31 adds 1 to the address of the symbol storage area (step S186). Next, the CPU 31 subtracts 1 from the number of reel checks (step S187). Next, the CPU 31 determines whether or not the number of reel checks is 0 (step S188). If the CPU 31 determines that the number of reel checks is not 0, it proceeds to step S185. When the CPU 31 determines that the number of reel checks is 0, the CPU 31 calculates the logical product of the display check data (here, the logical product with the above-described symbol code of each reel) and “01111111B”, and The logical sum with the display combination storage area is calculated (step S189). Next, the CPU 31 stores it as a display combination in the display combination storage area (step S190).

  In the present embodiment, a symbol arrangement table for defining symbol codes for each symbol arranged on the surface of each reel 3L, 3C, 3R is provided, and a logical product of symbol codes acquired according to the type of reel is taken. Therefore, according to each of the symbols arranged on the surface of the reel, the rotation of the reel can be performed without determining whether or not it matches each of the symbol combinations defined by the symbol combination table as in the past. It is possible to determine the position where the stop is made. That is, among the predetermined symbol combinations related to the provision of profits, a symbol combination not related to the symbol arranged at the position specified by the symbol counter (in other words, different from the symbol combination that the symbol constitutes). Since it is not necessary to determine whether or not the symbol combination) is displayed to the player, waste is eliminated and the processing is speeded up. As a result, it is possible to reduce the time required to determine the position where the reel rotation is stopped.

  Next, the CPU 31 determines whether or not bits 0 to 2 of the display combination are on (step S191). When the CPU 31 determines that bits 0 to 2 of the display combination are ON, the CPU 31 numbers the ON bits and acquires the payout number based on the payout number table (step S192). Next, the CPU 31 determines whether or not bit 7 of the display check data is on (step S193). When determining that bit 7 of the display check data is not on, the CPU 31 determines whether or not the payout number exceeds the maximum payout number prediction counter (step S194). When determining that the payout number exceeds the maximum payout number prediction counter (initial value is 0), the CPU 31 stores (ie, overwrites) the payout number in the maximum payout number prediction counter (step S195).

  When determining that bit 7 of the display check data is ON in step S193, the CPU 31 adds the value to the payout number counter and stores it (step S196). Next, the CPU 31 determines whether or not the payout number counter exceeds 15 (step S197). When determining that the payout number counter exceeds 15, the CPU 31 changes the value to 15 (step S198). When the CPU 31 determines after step S198 that it does not exceed 15 in step S197, after step S195, when it is determined that the number of payouts does not exceed the maximum payout number prediction counter in step S194, or it is displayed in step S191. When it is determined that the combination bits 0 to 2 are not on, the effective line counter is decremented by 1 (step S199). Next, the CPU 31 determines whether or not the valid line counter is 0 (step S200). When the CPU 31 determines that the effective line counter is not 0, the process proceeds to step S183, and when it is determined that the effective line counter is 0, the display combination search process ends.

  Next, the priority pull-in status acquisition process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the CB operating flag is on (step S211). When determining that the CB operating flag is on, the CPU 31 performs a CB operating process which will be described later with reference to FIG. 31 (step S212). In this process, a process for determining the priority pull-in status based on the winning number and the payout number is performed. When this process ends, the priority pull-in status acquisition process ends.

  When the CPU 31 determines in step S211 that the CB operating flag is not on, the CPU 31 performs an exclusive OR of the internal winning combination and the display combination, and calculates a logical product of the result and the display combination (step S213). By this process, it is determined whether or not there is a bit that is turned on only in the display combination storing area, and from this, whether or not the display combination is included in the internal winning combination, that is, the current check target symbol is: It is determined whether or not the determined internal winning combination is satisfied.

  Next, the CPU 31 determines whether or not all of bit 0 to bit 2 are 0 (step S214). When determining that all of bit 0 to bit 2 are not 0, the CPU 31 determines whether or not bit 0 is on (step S215). When CPU 31 determines that bit 0 is ON, CPU 31 sets “000H” as the priority pull-in status (step S216). That is, the priority pull-in status becomes “stop prohibited”, and erroneous display of symbol combinations that do not satisfy the internal winning combination is avoided.

  If the CPU 31 determines in step S214 that all of bits 0 to 2 are 0, it determines whether or not all of bits 3 to 5 are 0 (step S217). When the CPU 31 determines that all of bits 3 to 5 are not 0, or when it is determined in step S215 that bit 0 is not on, whether or not the number of stop buttons for which the pressing operation is effective is 1 or not. Is determined (step S218). If the CPU 31 determines that the number of stop buttons for which the pressing operation is effective is 1 (that is, the remaining rotating reel is 1), the CPU 31 proceeds to step S216.

  When the CPU 31 determines in step S218 that the number of stop buttons for which the pressing operation is valid is not 1, or when it is determined in step S217 that all of bits 3 to 5 are 0, the priority pull-in order table A head address (that is, an address corresponding to replay of priority 1) is set, 3 is set as the number of checks, and 1 is set as an initial value of priority (step S219).

  Next, the CPU 31 calculates the logical product of the pull-in data corresponding to the current priority order, the internal winning combination, and the display combination (step S220). Next, the CPU 31 determines whether or not the logical product is 0 (step S221). If the CPU 31 determines that it is not 0, it turns on the carry flag (step S222). After step S222 or when it is determined in step S221 that the logical product is 0, the CPU 31 rotates the bit pattern of the priority pull-in status (note that the initial value is 000H) including the carry flag to the left (step S223).

  Next, the CPU 31 subtracts 1 from the number of checks and adds 1 to the priority (step S224). Next, the CPU 31 determines whether or not the number of checks is 0 (step S225). When the CPU 31 determines that the number of checks is not 0, the CPU 31 proceeds to step S220. When determining that the number of checks is 0, the CPU 31 adds 1 to the priority pull-in status (step S226). That is, “000H” determined as the priority pull-in status is treated as “stop prohibition”. When this process ends, the priority pull-in status acquisition process ends.

  Next, with reference to FIG. 31, the processing during CB operation will be described.

  First, the CPU 31 determines whether or not the number of effective stop buttons is 1 (step S231). When the CPU 31 determines that the number of valid stop buttons is 1, it determines whether or not bits 3 to 5 of the display combination storage area are on (step S232). When CPU 31 determines that bits 3 to 5 of the display combination storage area are ON, it sets “000H” as the priority pull-in status (step S233). When this process ends, the process during CB operation ends.

  When the CPU 31 determines that the number of effective stop buttons is not 1 in step S231, or when it is determined in step S232 that bits 3 to 5 of the display combination storage area are not on, the display combination storage area Of the bits 0 to 2, the number of “1 (ie, on)” is calculated as the number of winning prizes (step S234). Next, the CPU 31 adds the value of the maximum payout number prediction counter to the value of the payout number counter, and rotates the bit pattern to the left three times (step S235). Next, the CPU 31 calculates a logical sum with the number of winning prizes (step S236). Thus, in the priority attraction-in status during CB operation, the upper 5 bits correspond to the sum of the payout number and the predicted maximum payout number, and the lower 3 bits correspond to the winning number. Next, the CPU 31 adds 1 and sets it as the priority pull-in status (step S237). When this process ends, the process during CB operation ends.

  Next, the reel stop control process will be described with reference to FIG.

  First, the CPU 31 determines whether or not a valid stop button has been pressed (step S241). When determining that the effective stop button is not pressed, the CPU 31 repeats the process of step S241. When so-called automatic stop is performed, it may be determined whether or not a predetermined time (for example, 30 seconds) has elapsed since the start switch 6S was turned on. When determining that a valid stop button has been pressed, the CPU 31 specifies the type of the stop button and invalidates the corresponding stop button (step S242). That is, an identifier indicating that the detection of the pressing operation is invalid, such as turning off the flag corresponding to the corresponding stop button, is stored in the RAM 33.

  Next, the CPU 31 extracts the number of sliding symbols from the stop table based on the type of the symbol counter and the stop button (step S243). Next, the CPU 31 performs a priority pull-in control process which will be described later with reference to FIG. 33 (step S244). In this process, based on the priority pull-in status determined for each symbol of the corresponding reel and the search order table, a predetermined range from the symbol of the stop start position of the corresponding reel (that is, the maximum number of sliding frames) The symbol having the highest priority among the symbols up to (i.e., if the priority pull-in status is the same, the search order is higher) is determined, and the reel rotation is stopped based on this symbol. Processing is performed.

  Next, the CPU 31 transmits a reel stop command to the sub control circuit 72 (step S245). The reel stop command includes data such as the type of the stopped reel. Next, the CPU 31 determines a reel corresponding to the pressed stop button as a search target reel (step S246). Next, the CPU 31 acquires a scheduled stop position as the symbol position data (step S247). Next, the CPU 31 stores “080H” in the stop check status storage area (step S248). Next, the CPU 31 performs the above-described symbol code storing process (step S249).

  Next, the CPU 31 determines whether or not there is a stop button for which the pressing operation is valid (step S250). When it is determined that there is no stop button for which the pressing operation is effective, the reel stop control process is ended. When the CPU 31 determines that there is a stop button for which the pressing operation is effective, the CPU 31 performs the aforementioned display combination prediction storing process (step S251). In this process, a process of determining a priority pull-in status corresponding to each symbol is performed for the rotating reels excluding the reels that have stopped rotating. When this process ends, the process moves to step S241.

  Next, the priority pull-in control process will be described with reference to FIG.

  First, the CPU 31 selects the expected display combination storing area according to the type of the stop button that has been pressed (step S271). Next, the CPU 31 sets 5 which is the maximum possible number of sliding pieces as the number of checks (step S272). Next, the CPU 31 determines whether or not the player is in the CB gaming state and the left stop button has been pressed (step S273). When the CPU 31 determines that it is in the CB gaming state and the left stop button is pressed, the CPU 31 changes the number of checks to 2 (step S274).

  After determining that the CPU 31 is in the CB gaming state and the left stop button has not been pressed after step S274, the CPU 31 counts the number of checks from the expected display combination storing area corresponding to the symbol counter. Are acquired and compared, and the maximum priority pull-in status is determined as the expected display combination data (step S275). Next, the CPU 31 sets a search order table and sets 1 as an initial value of the search order (step S276).

  Next, the CPU 31 acquires the number of sliding symbols corresponding to the current search order based on the number of sliding symbols extracted from the stop table (step S277). Next, the CPU 31 adds the address of the expected display combination storing area by the number of sliding frames, and acquires the priority pull-in status (step S278). Next, the CPU 31 determines whether or not the acquired priority pull-in status is the same as the expected display combination data (step S279). When the CPU 31 determines that the acquired priority pull-in status is not the same as the expected display combination data, the CPU 31 determines whether or not the number of sliding symbols has been saved (step S280). When the CPU 31 determines that the number of sliding pieces has not been saved, the CPU 31 saves the number of sliding pieces (step S281).

  After step S281 or when it is determined in step S280 that the number of sliding frames has been saved, the CPU 31 subtracts 1 from the number of checks and adds 1 to the search order (step S282). Next, the CPU 31 determines whether or not the number of checks is 0 (step S283). If the CPU 31 determines that the number of checks is not 0, it proceeds to step S277. When determining that the number of checks is 0, the CPU 31 restores the number of evacuated sliding pieces (step S284).

  After determining that the priority pull-in status obtained in step S284 is the same as the expected display combination data after step S284, the CPU 31 stores the number of sliding symbols and the planned stop position based on the symbol counter (step). S285). When the planned stop position is stored, a process for stopping the rotation of the reel is performed based on the planned stop position in an interrupt process (see FIG. 36) described later. It should be noted that the number of sliding pieces and the scheduled stop position are in an equivalent relationship because one is determined and the other is also determined. In this way, based on the internal winning combination, the highest priority is determined among the symbols arranged at the position specified by the position specifying means and each of the Y symbols consecutive thereto, and corresponds to the symbol. The rotation of the reel is stopped based on the number of sliding pieces to be performed (this is the most appropriate number of sliding pieces). When this process ends, the priority pull-in control process ends.

  Next, the bonus operation check process will be described with reference to FIG.

  First, the CPU 31 determines whether or not the display combination is RB (step S291). When it is determined that the display combination is RB, the CPU 31 performs RB operation processing based on the bonus operation table (step S292). When determining that the display combination is not RB, the CPU 31 determines whether or not the display combination is CB (step S293). When the CPU 31 determines that the display combination is not CB, the bonus operation check process ends. When determining that the display combination is CB, the CPU 31 performs CB operation processing based on the bonus operation table (step S294). After step S294 or after step S292, the CPU 31 clears the carryover combination storage area (step S295). When this process ends, the bonus operation check process ends.

  Next, with reference to FIG. 35, the bonus end check process will be described.

  First, the CPU 31 determines whether or not the RB operation flag is on (step S301). When determining that the RB operating flag is not on, the CPU 31 determines whether or not the bonus end number counter is 0 (step S302). When determining that the bonus end number counter is not 0, the CPU 31 ends the bonus end check process. When determining that the bonus end number counter is 0, the CPU 31 performs CB end processing (step S303). Specifically, the CB operating flag and the bonus end number counter are cleared. When this process ends, the bonus end check process ends.

  When determining that the RB operating flag is on in step S301, the CPU 31 determines whether or not a winning is achieved (step S304). When determining that a winning has been established, the CPU 31 decrements the winning possible number counter by 1 (step S305). Next, the CPU 31 determines whether or not the winning possible number counter is 0 (step S306). When the CPU 31 determines that the winable number counter is not 0, or when it is determined in step S304 that no win has been established, the CPU 31 subtracts 1 from the possible game number counter (step S307).

  Next, the CPU 31 determines whether or not the game possible number counter is 0 (step S308). When the CPU 31 determines that the possible game number counter is not 0, the bonus end check process ends. When it is determined that the possible game number counter is 0, or when it is determined in step S306 that the possible winning number counter is 0, the CPU 31 performs RB end time processing (step S309). Specifically, the RB operating flag, the winning possible number counter and the possible gaming number counter are cleared. When this process ends, the bonus end check process ends.

  Next, with reference to FIG. 36, an interrupt process with a cycle of 1.1173 ms, which is performed under the control of the CPU 31 of the main control circuit 71, will be described.

  First, the CPU 31 saves the register (step S311). Next, the CPU 31 performs input port check processing (step S312). Specifically, the CPU 31 checks the input of signals from each switch. Next, the CPU 31 performs a reel control process (step S313). Specifically, when a reel rotation start request is made, the reels 3L, 3C, and 3R start to rotate, and then rotate at a constant speed. When the scheduled stop position is stored, the rotation is decelerated and stopped after the symbol counter of the corresponding reel is updated to the same value as the scheduled stop position. For example, if the symbol counter is “0” and the stop control position is “4”, the reel rotation is stopped when the symbol counter is updated to “4”. Next, the CPU 31 performs a lamp / 7SEG driving process (step S314). Specifically, processing such as display of the number of payouts on the information display unit 18 is performed. Next, the CPU 31 restores the register (step S315). When this process ends, the interrupt process with a cycle of 1.1173 ms ends.

  In the following, the operations of the reel stop initial setting process, the expected display combination storage process, the symbol code storage process, the display combination search process, the priority pull-in status acquisition process, the CB operation process, the reel stop control process, and the priority pull-in control process described above Will be described with reference to FIG. FIG. 37 shows a storage example of the expected display combination storing area.

  In the following, in the CB gaming state, cherry, bell, and watermelon (that is, 00000111B) are stored in the internal winning combination storing area, and the stop start position of the left reel 3L corresponding to the first stop operation is “0”. ”, The stop start position of the middle reel 3C corresponding to the second stop operation is“ 0 ”, and the stop start position of the right reel 3R corresponding to the third stop operation is“ 0 ”. I will give you a description.

(Reel stop initial setting process)
First, in the reel stop initial setting process, a stop table for CB operation is determined, and a rotating identifier (0FFH) is stored in each area of the symbol storage area. Next, in the expected display combination storing process, “3” is stored as the number of display combination searches, “0” is set as the symbol position data, and “21” is set as the number of checks. Further, the left reel 3L is determined as a search target reel, and “000H” is stored in the stop check status storage area.

  Next, in the symbol code storing process, the leading address (the symbol position 20 address) of the symbol arrangement table for the left reel is set. Symbol position data (0) is added to the current address (symbol position 20) (symbol position 20) and stored in the reference address storage area. In addition, the head address of the symbol storing offset table corresponding to the left reel 3L is set. Further, the head address (center line) of the symbol storage area corresponding to the left reel 3L is set, and “5” is stored as the effective line counter.

  Then, the address (symbol position 20) stored in the reference address storage area is acquired, and the offset data (1) stored at the current address of the symbol storage offset table corresponding to the left reel 3L is added, The address is advanced (symbol position 0, corresponding symbol is cherry). The logical sum (ie, 10000001B) of the symbol code (ie, 10000001B) stored in the address (designation position 0) and the stop check status storage area (here, 000H) is the symbol storage area (centerline). Stored in the middle left reel). Further, the effective line counter is decremented by 1, the address of the symbol storing offset data table is incremented by 1, and the address of the symbol storing area is incremented by 3 (upper left reel on the top line).

  Thereafter, until the valid line counter is updated to 0, the same processing as described above is performed for each valid line, and the symbol code is stored at the address associated with the left reel 3L of each symbol storage area. Here, “10000001B” corresponding to the symbol “cherry” is located in the middle of the left reel of the center line, “00001000B” corresponding to the symbol “replay” is located in the upper portion of the left reel of the top line, and symbols are depicted in the lower portion of the left reel of the bottom line. "00000000B" corresponding to "Blank", "00001000B" corresponding to the symbol "Replay" above the left reel of the cross-down line, and "00000000B" corresponding to the symbol "Blank" below the left reel of the cross-up line (Note that the area corresponding to the other reels stores rotating identifiers).

  Next, in the display combination search process, the display combination storage area is cleared, the top address of the symbol storage area (center left reel center) is set, “5” is acquired as the effective line counter, and the number of reel checks “3” is set. The logical product of the display check data (0FFH = 11111111B) and the data (10000001B) stored at the current address in the symbol storage area (the middle reel on the center line) is calculated. As a result, the display check data is “10000001B Is updated.

  Subsequently, the symbol storage area address is incremented by 1 (center reel middle stage), and the number of reel check times is decremented by 1. Thereafter, until the number of times of the reel check is updated to 0, the logical product with the symbol code of each of the reels 3C and 3R (both being 0FFH indicating that they are rotating) is taken and the display check data is updated. (10000001B).

  Then, a logical product of the display check data and “01111111B” is obtained, and a logical sum of the result (00000001B) and the display combination storage area (000H) is obtained (00000001B) and stored in the display combination storage area. Is done. Here, since bit 0 of the display combination is ON, “15” is acquired as the payout number based on the payout number table. Further, since bit 7 of the display check data is not ON and the number of payouts exceeds the maximum payout number prediction counter (0), “15” is stored in the maximum payout number prediction counter.

  Thereafter, the same processing as described above is performed for each effective line until the effective line counter is updated to 0. As a result, “00000101B” is stored in the display combination storing area.

  Next, in the priority pull-in status acquisition process, since the CB is operating and the number of valid stop buttons is not 1, the number of bits 0 to 2 in the display combination storage area that is turned on is the winning prize. Calculated as the number (ie, one). Subsequently, the value (15) of the maximum payout number prediction counter is added to the value (0) of the payout number counter, the bit pattern is rotated to the left three times (01111000B), and the winning number (001H) is calculated. A logical sum is taken (01111001B). Then, “001H” is added to the logical sum (011111010B) and set as a priority pull-in status.

  Next, returning to the expected display combination storing process, the priority pull-in status is stored at the current address of the expected display combination storage area (design position 0 of the expected display combination storage area 1). Also, 1 is added to the address of the expected display combination storing area (symbol position 1 in the expected display combination storing area 1), 1 is added to the symbol check position (symbol position data is 1), and 1 is subtracted from the number of checks (20). ).

  The above-described processing is executed according to all symbol positions on all reels 3L, 3C, 3R. As a result, as shown in (1) of FIG. 36, the priority pull-in status corresponding to each symbol position is stored in each expected display combination storage area. In (1) of FIG. 36, the expected display combination storage area 1 corresponds to the left reel 3L, the expected display combination storage area 2 corresponds to the middle reel 3C, and the expected display combination storage area 3 corresponds to the right reel 3R.

(First stop operation)
First, in the reel stop control process, since the left stop button 7L is pressed when the symbol counter is “0”, the number of sliding pieces “1” is extracted from the CB operating stop table. Thereafter, in the priority pull-in control process, since the first stop operation is a pressing operation of the left stop button 7L, the expected display combination storing area 1 shown in (1) of FIG. 37 is selected.

  Next, “5”, which is the maximum possible number of sliding pieces, is set as the number of checks. However, since the player is in the CB gaming state and the left stop button is pressed, the number of checks is changed to “2”. . Then, in order from the address corresponding to the symbol position “0”, the priority pull-in statuses for the number of checks are acquired and compared, and the maximum priority pull-in status is searched. Here, “11110011B (payout number 15 + 15 and winning number 2)” at symbol position “1” is larger than “011111010B (paying number 15 and winning number 1)” at symbol position “0”, which has the highest priority. Since it is a pull-in status, it is determined as expected display combination data.

  Next, with reference to the search order table, the number of sliding pieces corresponding to the current search order is acquired based on the number of sliding pieces “1” extracted from the stop table. From the address of the expected display combination storing area 1 corresponding to the symbol position “0”, the number of sliding symbols (here, the number of sliding symbols 1 in the retrieval order 1) obtained based on the retrieval order table is the address ahead (the symbol position 1). ) Get the priority pull-in status stored in. Since the priority pull-in status acquired here and the expected display combination data are the same, “1” is determined as the number of sliding symbols, and the symbol position “1” is stored as the scheduled stop position. When the rotation of the left reel 3L is stopped based on the planned stop position “1”, the left display window 4L displays a bell in the upper row, a replay in the middle row, and a cherry in the lower row.

  As described above, when there are positions where a plurality of symbol combinations related to the payout of medals (here, bell-bell-bell and cherry-any-any) can be displayed, they are associated with these symbol combinations. When the number of payouts is equal (i.e., both 15), the position where the number of the symbol combinations can be displayed is larger (that is, the symbol position 2 where both the symbol combinations can be displayed). It is determined as the position to be stopped.

(After the first stop)
“080H” is stored in the stop check status storage area, and the symbol code is stored in each area of the symbol storage area for the left reel 3L whose rotation has been stopped in the symbol code storage process. Here, "10001000B" corresponding to the symbol "Replay" in the middle of the left reel on the center line, "10000010B" corresponding to the symbol "Bell" in the upper portion of the left reel on the top line, and the symbol in the lower portion of the left reel on the bottom line. “10000001B” corresponding to “Cherry”, “10000010B” corresponding to the symbol “Bell” on the upper stage of the left reel of the cross-down line, and “10000001B” corresponding to the pattern “Cherry” on the lower stage of the left reel of the cross-up line Is stored.

  In the expected display combination storing process, the priority pull-in status is determined for the middle reel 3C and the right reel 3R corresponding to the stop button for which the pressing operation is effective, as described above. As a result, as shown in (2) of FIG. 37, the priority pull-in status for all symbols of each reel is stored in the corresponding expected display combination storing area. In (2) of FIG. 37, the expected display combination storing area 1 corresponds to the middle reel 3C, and the expected display combination storing area 2 corresponds to the right reel 3R.

(Second stop operation)
First, since the middle stop button 7C is pressed when the symbol counter is “0”, the number of sliding pieces “3” is extracted from the CB operating stop table, and the second stop operation is the pressing operation of the middle stop button 7C. Therefore, the expected display combination storing area 1 is selected.

  Next, “011111011B (payout number 15 and winning number 2)” at the symbol position “2” is the maximum priority attraction-in status, and is determined as the expected display combination data. Next, the search order table is referred to, and an appropriate number of sliding pieces is searched in a search order based on the number of sliding pieces “3” extracted from the stop table. Here, the priority pull-in status that matches the expected display combination data is stored at the symbol position “2”, “2” is determined as the number of sliding symbols (corresponding to the search order “2”), and the scheduled stop position “ 2 "is determined. When the rotation of the middle reel 3C is stopped based on the planned stop position “2”, the middle display window 4C displays a bell at the upper stage, a replay at the middle stage, and a watermelon at the lower stage.

(After the second stop)
Similarly, “080H” is stored in the stop check status storage area, and the symbol code is stored in each area of the symbol storage area for the middle reel 3C whose rotation has been stopped by the symbol code storage process. Next, in the expected display combination storing process, the priority pull-in status is determined as described above for the right reel 3R corresponding to the stop button for which the pressing operation is valid. As a result, as shown in (3) of FIG. 37, the priority pull-in status for all symbols of the right reel 3R is stored in the corresponding expected display combination storing area. In (3) of FIG. 37, the expected display combination storing area 1 corresponds to the right reel 3R.

(Third stop operation)
First, since the right stop button 7R is pressed when the symbol counter is “0”, the number of sliding pieces “0” is extracted from the CB operating stop table, and the third stop operation is the pressing operation of the right stop button 7R. Therefore, the expected display combination storing area 1 is selected. Next, “011111011B (payout number 15 and winning number 2)” at symbol position “3” is the highest priority pull-in status, and “3” is determined as the number of sliding symbols according to the search order (search order “5”). ), The planned stop position “3” is determined. Then, when the rotation of the right reel 3R is stopped based on the planned stop position “3”, a bell is displayed on the upper stage, a watermelon is displayed on the middle stage, and a replay is displayed on the lower stage on the right display window 4R. Therefore, a combination of symbols related to the bell is displayed along the top line 8b.

  As described above, the gaming machine 1 of the present embodiment is predicted based on the combination of symbols displayed to the player according to the symbol positions “0” to “20” that can be specified by the symbol counter. When the priority draw-in status is determined based on the number of payouts and the number of winnings, and the stop operation is detected, the highest priority draw-in status among the predetermined number of symbols from the symbols placed at the stop start position The rotation of the corresponding reel is stopped on the basis of the determined symbol.

  That is, in addition to the amount of profits (payout number) given to the player, the rotation of the reel is stopped with reference to the number of symbol combinations related to medal payout that can be displayed to the player. Therefore, when a combination of a plurality of symbols can be displayed, even if the number of paid-out medals and the like associated with each other is the same, a position with a larger number that can be displayed is appropriately set. As a position, the rotation of the reel can be stopped. In addition, since only one of the symbol combinations is displayed (especially before the remaining spinning reel becomes one), the possibility that another symbol combination is displayed is excluded. It is also possible to prevent this, and it is possible to more appropriately reflect the profit to be obtained by the player in determining the position where the rotation of the reel is stopped.

  Although the present embodiment has been described above, the present invention is not limited to this. That is, a reel, start operation detecting means, internal winning combination determining means, reel rotating means, stop operation detecting means, position specifying means, predicting means, winning number calculating means, priority drawing order, provided in the spinning machine of the present invention The specific configurations of the determining means, the reel stopping means, the profit determining means, etc. are not limited to the elements of the present embodiment described above, and can be arbitrarily changed.

  In the present embodiment, the aforementioned expected display combination storing process is performed before the stop button is pressed, but the present invention is not limited to this. The time when the expected display combination storing process is performed may be before the reel rotation is actually stopped, or may be after the stop button is pressed.

  In this case, only the priority pull-in status corresponding to each symbol within a predetermined range in the reel rotation direction may be determined from the symbol corresponding to the stop start position, and each may be stored. More specifically, instead of the process of step S133 (FIG. 27) described above, the stop start position specified by pressing the stop button is set as symbol position data, and the maximum possible number of sliding symbols is set as the number of checks. “5” may be applied (if 1 continues to be added to the symbol position data and becomes 21, it is corrected to 0).

  Further, in this embodiment, there is provided a stop table that defines the number of sliding pieces according to the value of the symbol counter when the stop button is pressed, that is, the stop starting position, and the sliding piece determined based on the stop table. Although one search order table is selected from a plurality of search order tables based on the number, the present invention is not limited to this. For example, the type of search order table is specified according to each symbol (and the internal winning combination and the type of reel) so that one search order table can be selected from a plurality of search order tables according to the stop start position. A search order determination table may be provided. In addition, it is not always necessary to provide a plurality of search order tables, and the optimum number of sliding symbols may be searched in a predetermined search order (for example, 0 → 1 → 2 → 3 → 4). good. Similarly, it is not always necessary to have a stop table as in the present embodiment, and each symbol within a predetermined range in the reel rotation direction is compared with the symbol corresponding to the stop start position, and the expected display combination is stored. The optimum number of sliding symbols may be searched based on the priority pull-in status stored in the area.

  In the present embodiment, one stop table is selected from a plurality of types of stop tables based on the winning number stored in the winning number storage area. Instead, the internal winning combination is stored. One stop table may be selected based on the internal winning combination stored in the area (note that the winning number is a subordinate concept of the internal winning combination). In this embodiment, a specific stop table is uniquely selected based on the winning number. However, a plurality of types of stop tables may be distributed by performing a dedicated lottery or the like. This is because, for example, when the winning number is 2 (in other words, when the internal winning combination is a bell), the number of sliding pieces (or the planned stop position) so that “Bell-Bell-Bell” is displayed diagonally. A lottery is used to determine one of a stop table that defines the number of sliding pieces (or a planned stop position) so that “bell-bell-bell” is displayed in parallel. Etc. can be realized.

  Also, the device configuration shown in FIGS. 1 and 2, the circuit configuration shown in FIG. 4 and its peripheral devices, the table configurations shown in FIGS. 5 to 17, and the RAMs shown in FIGS. 18 to 21 applied in this embodiment. The storage area configuration, the flowchart configurations shown in FIGS. 23 to 36, and the like can be arbitrarily changed or modified without departing from the spirit of the present invention.

  In addition to the pachislot machine as in the present embodiment, the present invention can be applied to gaming machines such as slot machines and video slots. Furthermore, a game can be executed by applying the present invention to a game program in which the operation in the slot machine is executed in a pseudo manner for a home game machine. In that case, a CD-ROM, FD (flexible disk), or any other recording medium can be used as a recording medium for recording the game program.
