Description

  The present invention relates to a slot machine that determines the generation of a right to execute a game advantageous to a player in a game in which a result is determined by a combination of symbols displayed when a reel on which a plurality of symbols are drawn is stopped.

  Conventionally, a slot machine is widely known as one of gaming machines. In this type of slot machine, when the player inserts a prescribed number of game media such as medals and game balls, the operation of the start switch becomes effective. As a result, when the player operates the start switch, the game is started, the lottery is performed, and a plurality of reels each having a plurality of symbols are rotated. When the rotation speed of the reel reaches a certain speed, the operation of the stop switch provided corresponding to each reel becomes effective, and every time the player operates the stop switch, in accordance with the result of the role lottery, The corresponding reel is stopped, and when all reels stop, one game result is determined. And, if the combination of symbols displayed along the active line defined in the display window of the reel corresponds to some combination, it means that the combination is established, and the privilege corresponding to that combination Is given to the player, and one game is completed. On the other hand, when a combination is not established, one game is completed without a privilege being granted.

  In general, the above-mentioned combination includes a small combination, a re-playing combination, and a special combination. When the small combination is established, a predetermined number of medals are paid out, and when the re-playing combination is established, As such, when a special combination is established, a special game can be performed from the next game until a predetermined termination condition is established as a bonus. In this special game, since the payout rate is set higher than games other than the special game (hereinafter referred to as general game), it can be said that the game is advantageous to the player who can acquire more medals.

  In recent years, slot machines that can play games advantageous to the player even during general games have appeared. In this type of slot machine, when a specific small combination is won in a lottery drawing during a general game, the specific small combination is established only when the player performs a predetermined operation on the stop switch. It has become. Here, the “predetermined operation” is, for example, a timing at which a plurality of stop switches are operated in the order determined by the lottery, or a combination of symbols determined by the lottery can be stopped along the effective line. Operation of a stop switch. Therefore, unless the player performs “predetermined operation” with respect to the stop switch, the specific small role described above cannot be established. That is, if the player does not know the content of the “predetermined operation”, the player performs the specific small role described above except when the operation performed on the stop switch coincides with the “predetermined operation”. It cannot be established. Therefore, when the above-mentioned specific small role is won in the combination lottery during the general game, the general game can be switched between a period for notifying the player about the “predetermined operation” and a period for not performing the notification. Among them, games that are advantageous to the player and games that are not so are realized.

  The conditions for shifting to the above-described period of notification regarding the “predetermined operation” (hereinafter referred to as assist time (AT)), that is, the conditions under which an advantageous game is performed vary depending on the type of slot machine. For example, in the slot machine described in Patent Document 1, first, an AT lottery for determining whether or not to grant a right to transfer to an AT (hereinafter simply referred to as “right”) is performed to grant the right. Is determined, an AT mode shift lottery is performed to determine whether or not to shift to AT. Then, when winning the transition lottery, the game shifts to an AT of 18 games (that is, a notification regarding “predetermined operation” is performed during 18 games). In addition, in the AT lottery, when it is determined that the right is granted, the number of times of shifting to the AT is also determined. As a result, when a plurality of times of transition are determined, a plurality of transitions to the AT are guaranteed for one right.

  Further, in the slot machine described in Patent Document 1, AT lottery is performed under two types of modes, a high probability AT lottery mode and a low probability AT lottery mode. Is determined according to the result of the role lottery performed prior to the AT lottery. When AT lottery is performed in the high-probability AT lottery mode, there is a higher possibility that the number of transitions to AT for one right will be greater than when AT lottery is performed in the low-probability AT lottery mode.

JP 2003-093599 A

  By the way, in the slot machine described in Patent Document 1, the role lottery (that is, the lottery in the AT lottery mode) is always performed prior to the AT lottery. It is very difficult for the player to determine whether it is determined under the high probability AT lottery mode or the low probability AT lottery mode. That is, for example, the player can guess the AT lottery mode at that time from the previous game result or the like, but when the AT lottery is performed in the next game, the AT lottery mode may be changed. For this reason, for example, a player guesses that an AT lottery was performed under the high-probability AT lottery mode, and based on the guess, a prediction is made that the number of AT transitions will increase. If the AT ends with a small number of transitions, it cannot be determined whether or not the guess is wrong. Therefore, while reducing the willingness to guess the AT lottery mode based on its own analysis, the expectation for a more advantageous AT based on the guess may be nullified, and as a result, the interest of the game may be impaired.

  The present invention has been made in view of the above problems, and in the case of performing lottery for selecting one event from a plurality of events based on the selection probability determined by lottery, It is an object of the present invention to provide a slot machine capable of determining whether or not an estimated selection probability is correct when an event to be selected is predicted based on the predicted event. .

In order to solve the above-described problems, the present invention provides a combination of symbols displayed in advance along a winning line when a plurality of reels on which a plurality of types of symbols are displayed are stopped. If it corresponds to any of the roles, it is a slot machine that performs a game that gives a player a privilege according to the role,
Random number generating means for generating a random number within a predetermined numerical range;
A right to execute an advantageous game that is highly likely to be given the privilege, and a plurality of types of right occurrence state designation information each indicating a state of the right to be generated, and the plurality of types of right occurrence state designation information For each of a plurality of transition destination information indicating a selection probability state to be a transition destination among a plurality of types of selection probability states having different probabilities of being selected from any one of the above, the numerical range is plural without overlapping A right lottery table storing means for storing a lottery table group assigned to each of the plurality of types of selection probability states;
Probability state storage means for storing the current selection probability state;
A right storage means for storing the right;
Among the lottery tables constituting the lottery table group, the lottery table corresponding to the current selection probability state stored in the probability state storage unit is referred to, and the random number value extracted from the random number generation unit is included. When the divided numerical value range is assigned to any of the plurality of types of right occurrence state designation information, the right of the state designated by the assigned right occurrence state designation information is stored in the right storage means, When assigned to any of a plurality of destination information, the current selection probability state stored in the probability state storage means is updated to the selection probability state indicated by the assigned destination information. Rights lottery means for performing rights lottery,
Advantageous game execution means for executing the advantageous game on the condition that the right is stored in the right storage means;
It is characterized by having.

  Here, “advantageous game” means, for example, a game at a so-called replay time or a game at an AT. In addition, the “right state to be generated” indicates what conditions are given to “advantageous games” executed based on the generated right or how the right after occurrence is It is a "state" of. In other words, the right generation state designation information indicates the conditions given to the “advantageous game” executed based on the generated right and how the right is generated (for example, how many rights are generated). Is information to specify. Further, “each divided numerical value range obtained by dividing a numerical value range into a plurality without overlapping” means that there is no overlapping numerical value between the divided numerical value ranges. For example, when the random number generation means generates a random number within an integer numerical range of 0 to 9, divided numerical ranges such as 0 to 6 and 4 to 9 (in this case, 4, 5, and 6 overlap) It means not to be. Further, the number of times of execution of the “advantageous game” based on one right may be one game or a plurality of predetermined games.

  In the slot machine according to the present invention, one of a plurality of types of right generation state designation information or transfer destination information is selected based on the random number generated by the random number generation means, and any one of the plurality of types of right generation state designation information is selected. Is selected, the right of the state specified by the selected right occurrence state specifying information is stored in the right storage means, and if any of the plurality of types of transfer destination information is selected, The current selection probability state stored in the probability state storage means is updated to the selection probability state indicated by the selected destination information. That is, when the right occurrence state designation information is selected at a lottery opportunity and the selection of the right occurrence state designation information and the update of the selection probability state are not performed at the same time, It will be selected under the selection probability state most recently updated at the previous lottery opportunity.

  For this reason, for example, when the current selection probability state is estimated based on its own analysis, and the prediction of the state of the right that has occurred is made based on the estimation, the advantageous game executed is predicted When the result is contrary to the state of the right, it can be determined that there is a high possibility that the estimated selection probability state is incorrect. In addition, since a plurality of types of right occurrence state designation information and transfer destination information are collectively set as a lottery object in a single lottery, it is possible to reduce the load required for the lottery process as compared to the case of lottery individually. it can.

In the slot machine described above, the right generation state designation information is information for designating the number of rights to be generated.
The right lottery means, when the divided numerical value range including the random number value extracted from the random number generation means is assigned to any of the plurality of types of right generation state designation information, The number of the rights designated by the status designation information is stored in the rights storage means.

  In the slot machine according to the present invention, the advantageous game executed when the current selection probability state is estimated based on its own analysis and the number of rights generated is predicted based on the estimation. Is different from the predicted number, it can be determined that the estimated selection probability state is likely to be incorrect. This stimulates the player's willingness to infer a more accurate selection probability state, and in order to achieve this, a game such as playing a game to further research and analyze the slot machine There is a possibility to increase motivation.

Further, according to the present invention, in the slot machine described above, the right occurrence state designation information includes a probability that the advantageous game executed based on the right associated with the generated right is continuously executed. Is a continuation probability indicating
The right lottery means, when the divided numerical value range including the random number value extracted from the random number generation means is assigned to any of the plurality of types of right generation state designation information, Storing the right associated with the continuation probability designated by the state designation information in the right storage means;
When the advantageous game is executed by the advantageous game execution means, whether to execute the advantageous game according to the continuation probability associated with the right that is a condition for executing the advantageous game. A continuous lottery means for performing a continuous lottery to determine whether or not,
The advantageous game executing means ends the advantageous game being executed on condition that the continuous lottery means determines that the advantageous game is not to be continued.

  In the slot machine according to the present invention, when the current selection probability state is estimated based on its own analysis and the continuation probability of the advantageous game is predicted based on the estimation, the advantageous game executed is Contrary to the predicted continuation probability, if it is terminated early or executed for a long time, it can be determined that there is a high possibility that the estimated selection probability state is incorrect. This stimulates the player's willingness to infer a more accurate selection probability state, and in order to achieve this, a game such as playing a game to further research and analyze the slot machine There is a possibility to increase motivation.

Further, the present invention provides a plurality of stop instructing means which are provided corresponding to each of the plurality of reels and instruct rotation stop of the corresponding reels according to an operation from the outside in any of the slot machines described above. ,
Reel stop control means for stopping the rotation of the reel corresponding to the stop instruction means in response to an instruction from the stop instruction means;
An operation order determining means for determining whether or not an operation from the outside with respect to the plurality of stop instructing means is performed in a predetermined order until all of the plurality of reels are stopped,
The right lottery table storage means assigns to the destination information indicating a selection probability state having a lower probability that the right occurrence state designation information is selected than the current selection probability state among the plurality of transition destination information. Storing a low selection probability state transition lottery table in which a numerical range is set wider than the divided numerical range to be assigned to destination information indicating other selection probability states;
When the right lottery means determines that the plurality of stop instruction means are operated in an order other than the predetermined order by the operation order determination means, based on the low selection probability state transition lottery table, A lottery for the transition of the selection probability state is performed.

  In the slot machine according to the present invention, when a plurality of stop instruction means are not operated in a predetermined operation order, a lottery based on the low selection probability state transition lottery table is performed, and as a result, any right occurrence state designation There is a high possibility that the information is shifted to a selection probability state where the possibility of selecting information is lower. Thereby, it is possible to obligate the player to operate a plurality of stop instruction means in a predetermined operation order. If the plurality of stop instruction means are operated in an order other than the predetermined order, When there is a slot machine with a specification that makes a transition to an advantageous state (for example, a state where the possibility of playing an advantageous game is high), it is possible to suppress the easy transition to the advantageous state. .

  In addition, in any one of the slot machines described above, the present invention has a higher selection probability state in which the right occurrence state designation information is selected from the plurality of types of selection probability states. In the associated lottery table, the divided numerical value range to be assigned to the right occurrence state designation information that is more advantageous to the player is set wider among the plurality of types of right occurrence state designation information.

  Here, “right generation state designation information advantageous to the player” means, for example, if the right generation state designation information specifies the number of rights generated, a right generation that specifies a larger number of occurrences This refers to state designation information. If the right occurrence state designation information designates a continuation probability of an advantageous game to be executed, it means right occurrence state designation information that designates a higher continuation probability.

  In the slot machine according to the present invention, as the current selection probability state is a selection probability state with a higher probability of selecting any right occurrence state designation information, the right occurrence state designation information that is more advantageous to the player is selected. Is more likely. For this reason, as the current selection probability state estimated by the player is a selection probability state with a higher right selection probability, the right to be generated is more advantageous (for example, the number of rights that have been generated is greater. It can be expected that an advantageous game continuation probability based on the game will be high). In addition, when a game that is advantageous against the expectation is finished in a short period of time, the player can determine that the selection probability state estimated by the player is likely to be incorrect.

Further, the present invention relates to any of the above-mentioned types of roles, based on a lottery probability preliminarily associated with each of the lottery objects, with the plurality of types of roles and loses as lottery objects. Or a role lottery means for performing a role lottery for lottery,
Reel stop control means for performing stop control of the plurality of reels so that a symbol combination corresponding to a winning combination or a loss drawn by the winning lottery means is displayed along the winning line,
The right lottery table storage means stores a plurality of types of lottery table groups according to the result of the role lottery,
The right lottery means performs the right lottery based on the lottery table group corresponding to the result of the role lottery,
In the lottery table constituting the lottery table group corresponding to the result of the lottery, the current selection probability among the plurality of types of selection probability states, as the result of the lottery that can be lower probability The division numerical value range to be allocated is set wider in the destination information indicating the selection probability state in which the right occurrence state designation information is more likely to be selected than the state.

  Here, there may be one or a plurality of winning combinations drawn by one winning combination. In addition, “losing” means that no winning combination is drawn, and “design combination corresponding to losing” refers to a symbol combination other than symbol combinations corresponding to a plurality of types of winning combinations. In addition, the “result of lottery” includes winning a predetermined combination, winning a plurality of predetermined combinations, or losing a combination.

  In the slot machine according to the present invention, it is possible to determine the result of the role lottery from the symbol combination displayed along the winning line, and since the possibility that the determined result of the lottery will be the result is higher than the present right. It can be inferred whether or not a selection probability state with a high probability of selection has been entered. Accordingly, it is possible to predict whether or not the right occurrence state designation information is selected based on the estimated selection probability state, and the player can be motivated to guess the selection probability state.

  As described above, according to the slot machine of the present invention, when performing lottery to select one event from a plurality of events based on the selection probability determined by lottery, based on the estimated selection probability, When an event to be selected is predicted, if the event does not become as predicted, it is possible to determine whether or not the estimated selection probability is correct.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
An appearance of the slot machine 10 according to the present embodiment is shown in FIG. FIG. 1 is a front view of the slot machine 10. In FIG. 1, a front panel 20 is provided on the front surface of the casing of the slot machine 10. A display window 22 for displaying symbols printed on the outer peripheral surfaces of the three reels 40L, 40C and 40R rotatably provided inside the slot machine 10 is formed at the approximate center of the front panel 20. Yes. Each of the reels 40L, 40C, and 40R is provided such that the respective rotation axes are arranged on the same straight line in the horizontal direction, each having a ring shape, and 21 symbols are printed at equal intervals on the outer peripheral surface thereof. A strip of reel tape is affixed. From the display window 22, when the reels 40L, 40C, and 40R are stopped, among the 21 symbols printed on each reel, three symbols that are continuous along the rotation direction of each reel are visually recognized. It is possible. That is, 3 [symbol] × 3 [reel] = 9 symbols in total are stopped and displayed on the display window 22. Here, among the three consecutive symbols displayed when the reels 40L, 40C, and 40R are stopped, the uppermost stop display position is the upper stage U, the middle stop display position is the middle stage M, and the lowermost figure. The stop display position is set to the lower stage L.

  The display window 22 has five pay lines that cross the reels 40L, 40C, and 40R. The five winning lines are a right-upward oblique winning line L1 crossing the lower stage L of the left reel 40L, the middle stage M of the middle reel 40C, and the upper stage U of the right reel 40R and the left reel 40L in the display window 22. The upper horizontal winning line L2 crossing each upper stage U of the middle reel 40C and the right reel 40R, the middle horizontal winning line L3 crossing each middle stage M, the lower horizontal winning line L4 crossing each lower stage L, and the left reel 40L The upper stage U, the middle stage M of the middle reel 40C, and the oblique lower right diagonal winning line L5 crossing the lower stage L of the right reel 40R. Thus, each winning line passes through any one of the three stop display positions (upper U, middle M, and lower L) of the reels 40L, 40C, and 40R.

  Each of the winning lines L1 to L5 is a reference line for determining a combination of symbols corresponding to a plurality of predetermined types (described later), and when the reels 40L, 40C, and 40R are stopped, A combination of three symbols that are stopped and displayed at each stop display position crossed by a winning line (hereinafter referred to as an active line) that is considered to be valid among the five winning lines corresponds to one of the roles. And that role was established.

  In addition to the display window 22, the front panel 20 is provided with various lamps and a display for notifying the player of various information related to the game. First, on the left side of the display window 22, operation instruction lamps 24L, 26c, and 24R are provided in order from the top in FIG. These operation instruction lamps 24L, 26c, and 24R are used to instruct the player in the operation order of stop switches 37L, 37C, and 37R, which will be described later, when the reels 40L, 40C, and 40R are rotating. That is, the left stop switch 37L is operated when the operation instruction lamp 24L is lit, the middle stop switch 37C is operated when the operation instruction lamp 26c is lit, and the right stop switch 37R is operated when the operation instruction lamp 24R is lit. Indicates that it should be.

  Below the display window 22, bet number (betting number) display lamps 26 a, 26 b, 26 c, a credit number display 27, and an acquired number display 28 are provided in order from the left in FIG. 1. The bet number display lamps 26a, 26b, and 26c are for displaying the number of medals inserted in one game. That is, when one medal is inserted, only the bet number display lamp 26a is lit, and when two medals are inserted, the bet number display lamps 26a and 26b are lit and three medals are inserted. The bet number display lamps 26a, 26b, and 26c are turned on. Here, the slot machine 10 is a so-called three-sheet betting machine in which one game can be performed by inserting three medals and the winning lines L1 to L5 are all active lines. The credit amount indicator 27 is a two-digit 7-segment indicator, and displays the number of medals credited (stored) in the slot machine 10 (more specifically, stored in the RAM 110 described later). . The acquired number display 28 is a two-digit 7-segment display, and displays the number of medals to be paid out to the player in the slot machine 10 according to the game result.

  A substantially horizontal operation panel unit 30 is provided below the front panel 20 described above. A medal slot 32 for inserting medals into the slot machine 10 is provided on the upper right side of the operation panel 30. A medal counter (not shown) is provided inside the medal insertion slot 32. The medal inserted from the medal insertion slot 32 is detected and the number of the medals is counted. A 1-bet switch 34 and a maximum bet switch 35 that can insert credited medals into the slot machine 10 are provided on the upper left side of the operation panel 30. The 1-bet switch 34 is a switch for inserting only one medal that is credited every time it is operated into the slot machine 10 as a game betting target. The maximum bet switch 35 is a switch for inserting three of the credited medals into the slot machine 10 as a game betting target.

  When three medals are inserted into the slot machine 10 from the medal insertion slot 32 or by operating various bet switches 34 and 35, the bet number display lamps 24a, 24b, and 24c are sequentially displayed every time a medal is inserted. The winning lines L1 to L5 become effective lines. Further, when medals are inserted by operating the various bet switches 34 and 35, the number of inserted medals is subtracted from the number of credits stored in the RAM 110, which will be described later. The value displayed in 26 is also subtracted. When a prescribed number (three) of medals have already been inserted, and further medals are inserted from the medal insertion slot 32, the number of inserted medals is added to the number of credits stored in the RAM 110. And is added to the value displayed on the credit amount display 26.

  A start switch 36 is tiltably provided on the left side of the front surface of the operation panel unit 30. When the player inserts a prescribed number (three) of medals into the slot machine 10 and then tilts the start switch 36, the three reels 40L, 40C and 40R described above start to rotate all at once. As a result, the symbols printed on the outer peripheral surfaces of the reels 40L, 40C, and 40R are moved and displayed on the display window 22 from top to bottom. Three stop switches 37L, 37C, and 37R are provided at the front center portion of the operation panel 30. Here, the left stop switch 37L corresponds to the left reel 40L, the middle stop switch 37C corresponds to the middle reel 40C, and the right stop switch 37R corresponds to the right reel 40R. The stop switches 37L, 37C, and 37R are operated by the player when the rotation speeds of the three reels 40L, 40C, and 40R reach a predetermined steady rotation speed (for example, 80 rotations / minute).

  When the player pushes the left stop switch 37L, the left reel 40L stops. When the middle stop switch 37C is pushed, the middle reel 40C stops and the right stop switch 37R is pushed. Sometimes the right reel 40R stops. At this time, each of the three reels 40L, 40C, and 40R has the center position of any three consecutive symbols out of the symbols drawn on the outer peripheral surface of each reel, the upper U in the display window 22, Stop control is performed so as to be positioned at the center of each of the middle stage M and the lower stage L. Here, a position where the center of the symbol coincides with the center of the stop display position is referred to as a fixed position. In the slot machine 10, when the player operates the stop switch to stop the corresponding reel, reel stop control is performed so that the symbol always stops at a fixed position.

  A lower panel 50 on which a model name of the slot machine 10 and characters adopted as a motif are drawn is disposed below the operation panel 30. A medal payout opening 60 for paying out medals to the player is provided at a substantially lower center of the lower panel 50. That is, when the reels 40L, 40C, and 40R are stopped and the combination of the three symbols stopped and displayed along the active line corresponds to the small role, the hopper (inside the slot machine 10) (Not shown) is activated and the number of medals corresponding to the small combination is paid out. Then, the paid-out medals are discharged from the medal payout outlet 60 and stored in the tray 61. On the right side and the left side of the medal payout opening 60, sound transmission holes 62R and 62L are provided for allowing sounds emitted from speakers 64R and 64L (described later) housed inside the slot machine 10 to pass outside. Yes.

  Above the front panel 20, an image display device 70 composed of a liquid crystal display panel is provided. The image display device 70 is not limited to the above-described liquid crystal display panel, and any other image display device can be used as long as the image information and the character information can be visually recognized by the player during the game. The image display device 70 displays a game history, an effect image during a special game, an effect image displayed at the time of transition to an RT game, an effect image according to a result of a role lottery, a game progress (medal insertion → start switch) It is possible to display an effect image or the like corresponding to 36 operation → reel rotation → operation of stop switches 37L, 37C, 37R → all reel rotation stop). Above the image display device 70, there is provided an upper effect lamp 72 that blinks in a pattern corresponding to the established combination when the reels 40L, 40C, 40R are stopped and any combination is established.

  Next, with reference to FIG. 2, the arrangement of symbols printed on the reel tape attached to the outer peripheral surfaces of the reels 40L, 40C and 40R will be described. As described above, 21 symbols are printed on the outer peripheral surfaces of the reels 40L, 40C, and 40R. One design is printed. Further, there are eight types of symbols displayed in each symbol display area, and a type code (not shown) is predetermined according to each type. The types of symbols in the present embodiment include the “red 7” symbol representing the number 7 in red, the “white 7” symbol represented in white, the “BAR” symbol with a bar-like lump motif, and the cherries. "Cherry" design with the motif of "Watermelon" design with the motif of watermelon, and the motif of the bell, but the different bells "Bell 1" design and "Bell 2" design, and plum motif "Plum" design, "Emblem" design with a fictional emblem, and "Jewel" design with a jewel motif.

  In addition, symbol numbers “0” to “20” are set in advance in each symbol display area of the reel tape attached to each of the reels 40L, 40C and 40R. As shown in FIG. The number is associated with a symbol type code printed in the symbol display area corresponding to the symbol number, and stored in the ROM 108 described later. These pieces of information are referred to when the symbols displayed at the respective stop display positions (upper U, middle M, and lower L) of the display window 22 are identified. Hereinafter, the symbol number and the type code are collectively referred to as symbol identification information. When the reel tapes having the contents shown in FIG. 2 are attached to the outer peripheral surfaces of the corresponding reels 40L, 40C, and 40R, the symbols of symbol numbers “0” and “1” are continuous in the symbol array of FIG. become.

  When the reels 40L, 40C, and 40R rotate, the three symbols of each reel displayed in the display window 22 are moved and displayed in the direction in which the values of the three consecutive symbol numbers increase. For example, when symbols of symbol numbers “1”, “2”, and “3” are displayed from the lower L to the upper U of the display window 22, the symbols that are displayed thereafter are symbol numbers “2”. ”,“ 3 ”,“ 4 ”→ design numbers“ 3 ”,“ 4 ”,“ 5 ”→ design numbers“ 4 ”,“ 5 ”,“ 6 ”→... When the symbol numbers “19”, “20”, and “0” are displayed, the symbol numbers, symbol numbers “20”, “0”, “1” → symbol numbers “0”, “1”, “ 2 ”→“ 1 ”,“ 2 ”,“ 3 ”→... Three consecutive symbols from symbol numbers“ 0 ”to“ 20 ”cyclically until the reel stops. Scroll display.

Are input to the CPU 106. Instead of generating a random number by the random number generator 112, a random number may be generated by a calculation process of the CPU 106.

  The CPU 106 controls various devices connected to the input / output bus 104 according to the result of processing the various control programs described above. First, the CPU 106 outputs a driving pulse to the motor driving circuit 114, and performs rotation control of the stepping motors 80L, 80C, and 80R. Each of the stepping motors 80L, 80C and 80R is provided on the inner peripheral side of the three reels 40L, 40C and 40R, and the rotation centers of the reels 40L, 40C and 40R are attached to the rotation shafts of the stepping motors 80L, 80C and 80R. ing. The motor drive circuit 114 is connected to the stepping motors 80L, 80C, and 80R, and rotates each stepping motor one step each time a drive pulse is output from the CPU 106. Further, the CPU 106 transmits various types of information related to games in the slot machine 10 (details will be described later) to the sub-control circuit 200 described below through the connection line 118 via the interface circuit 102.

≪Description of sub control circuit≫
Next, the configuration of the sub control circuit 200 will be described with reference to FIG. The connection line 118 described above is connected to the interface circuit 202 connected to the input / output bus 204 of the sub control circuit 200. Various types of information transmitted from the main control circuit 100 to the sub control circuit 200 are converted into predetermined signals by the interface circuit 202, supplied to the input / output bus 204, and temporarily stored in the RAM 210. The input / output bus 204 is configured to input / output data signals or address signals to / from the CPU 206. The input / output bus 204 is also connected with a ROM 208, a RAM 210, a lamp driving circuit 218, a display driving circuit 220, and a speaker driving circuit 222.

  The ROM 208 stores a control program for controlling the lamp driving circuit 218, the display driving circuit 220, and the speaker driving circuit 222, and initial data for executing the control program. The ROM 208 also stores various image data to be displayed on the image display device 70, performance sound data to be emitted from the speakers 64L and 64R, pattern data for blinking the upper effect lamp 72, and the like. The ROM 208 further includes a control program (see FIG. 23) for executing an ART game, which will be described later, a control program (see FIG. 24) for performing a lottery and the like regarding whether or not to grant the right to execute the ART game, and an ART game. A control program (see FIG. 25) for performing a lottery on whether or not to continue is also stored. In addition, various lottery tables (see FIGS. 12, 13, and 14) for performing processing related to these ART games are also stored.

  The RAM 210 stores various data generated / fluctuated in the process of executing the various programs described above, flag ON / OFF states, and stop switches operated as a result of the role lottery transmitted from the main control circuit 100. Information to be shown, game results, and various information such as the current game state / RT state described above are also stored.

  The lamp driving circuit 218 lights and drives the operation instruction lamps 24L, 24C, 24R and the upper effect lamp 72 in accordance with driving commands output from the CPU 206 based on various information signals supplied from the main control circuit 100. The display driving circuit 220 causes the image display device 70 to display image data, character data, and the like read from the ROM 208 by the CPU 206 based on the information signal supplied from the main control circuit 100. Thereby, on the image display device 70, image data is displayed as an effect screen, or character data is displayed as a message.

Output audio.

[Explanation of functional block diagram]
Next, a functional block diagram of the control circuit of the slot machine 10 is shown in FIG. In the following description, the same components as those shown in FIGS. 1 and 3 are denoted by the same reference numerals, and detailed description thereof is omitted. First, there are a main control circuit 100 and a sub-control circuit 200 as control circuits, and both are electrically connected. The main control circuit 100 is electrically connected to the operation means 300 and the motor drive circuit 114. The sub-control circuit 200 is electrically connected to notification means 600 including speakers 64L, 64R, an image display device 70, an upper effect lamp 72, and operation instruction lamps 24L, 24C, 24R. The operation unit 300 includes a game rotation start instruction unit 310 including a start switch 36 and a stop instruction unit 320 including three stop switches 37L, 37C, and 37R. The operation means 300 is not limited to a switch, and any means can be applied as long as it generates an operation signal based on an operation using the limbs of the player. In addition, the notification unit 600 is not limited to a sound or light notification of the player, but for example, a vibration generator such as a vibrator is provided inside the slot machine 10 to vibrate a specific part. It is possible to make a notification recognized by the player's tactile sense.

≪Description of main control circuit≫
The main control circuit 100 includes a combination lottery means 410, a reel control means 420, a winning determination means 430, and a winning processing means 440. The role lottery means 410 determines whether or not one or more of the predetermined roles are won by performing the role lottery. The predetermined roles described above are roughly classified into three types: small roles, replay (also called replay) roles, and bonus roles (special roles). A small combination is a combination in which a predetermined number of medals are paid out to the player when established, and a plurality of types of small combinations are determined according to corresponding symbol combinations. When a re-game is established, the game can be played again without inserting medals only for the next game. The game that can be played again is called replay (replay), and the effective line in the replay is the same as the effective line in the game in which the replaying role is established.

  When the bonus combination is established, a special game that is highly likely to be able to acquire medals in each game is started from the next game until a predetermined end condition is satisfied. The special games in the slot machine 10 include a big bonus game (hereinafter referred to as BB game) and a regular bonus game (hereinafter referred to as RB game) depending on the end conditions. In the BB game, when the number of medals to be paid out exceeds a predetermined number (here, 200), the end condition is satisfied, and the game returns to the game (general game) before the transition to the special game. Also, in the RB game, when the game is played a predetermined number of times (for example, 12 times) or the number of times the small role is won reaches a predetermined number of times (for example, 8 times), the RB game end condition is satisfied and the game returns to the general game.

  An RB game may be played even during a BB game, and the RB game at this time is particularly called an SRB game. This SRB game starts when the SRB combination is established during the BB game, and basically returns to the BB game when the termination condition of the SRB game is established, but when the termination condition of the BB game is satisfied during the SRB game Returns to general game immediately. Hereinafter, in the BB game, when a game state that is not an SRB game is particularly distinguished, it is referred to as a general game during BB.

<Description of role lottery means>
The role lottery means 410 includes, for example, a random number generator 112 (hard random number or the like) shown in FIG. 3, a random number extraction means 412 that extracts a random number generated by the random number generator 112, and a random number extracted by the random number extraction means 412. Random number determination means 414 is provided for determining the presence / absence of a winning combination and the winning combination by comparing a numerical value with a winning lottery table stored in the ROM 108. The control processing by the role lottery means 410 is shown in a role lottery processing subroutine (see FIG. 17) described later. Here, with reference to FIG. 6, the types of winning combinations that can be established in the slot machine 10 will be described. FIG. 6 shows the contents of the payout information in which the name of each winning combination, the symbol combination that will result in the winning combination, and the number of medals to be paid out to the player when the winning combination is established. This payout information is stored in the ROM 108 of the main control circuit 100 shown in FIG.

  As shown in FIG. 6, each combination that can be realized in the slot machine 10 is associated with a symbol combination including symbols drawn on the left reel 40L, the middle reel 40C, and the right reel 40R. This symbol combination means a symbol combination that is stopped and displayed along any one of the effective lines L1 to L5, and is referred to when the winning determination means 430 described later makes a winning determination. Moreover, when these symbol combinations are stopped and displayed along the active line, the corresponding combination is established, and a privilege corresponding to each combination is given to the player.

  That is, when the BB combination is established, the above-described BB game is started from the next game, and when the SRB combination is established in the general game during BB, the above-described SRB game is started from the next game as a privilege. Further, when a re-game is established, the next game becomes a re-game as a privilege. When a small combination is established, the number of medals corresponding to the type of the small combination established as a privilege is paid out to the player. More specifically, when a small combination 1 is established, two medals are paid out, and when any of the small combinations 2a to 2c is established, nine medals are paid out and a small combination 3 is established. In this case, 6 medals are paid out. Here, the formation of a combination in which medals are paid out as a small combination is also called winning.

  Further, in the symbol combination of the small role 1 shown in FIG. 6, “ANY” is described as the symbol of the middle / right reel, which indicates that the symbol is an arbitrary symbol. Therefore, if the “cherry” symbol of the left reel 40L stops at one of the positions of the active line (that is, the upper stage U, the middle stage M, the lower stage L), the small combination 1 wins at that time. Furthermore, when the “cherry” symbol on the left reel 40L stops at the upper stage U, the small role 10 has won on both active lines L2 and L5, and when it stops at the lower stage L, it is valid. The small role 1 has won a prize in both the effective lines of the lines L1 and L4. In this case, the number of medals to be paid out is 2 × 2 [effective line] = 4.

  Next, the contents of the winning lottery table stored in the ROM 108 will be described with reference to FIGS. First, in FIG. 7, (a) shows the contents of a role lottery table used in a general game (however, when the RT state is “non-RT”). (B) shows the contents of the role lottery table used in the RB game and the SRB game. (C) shows the contents of the role lottery table used in the BB general game. FIG. 8 shows the contents of the role lottery table used when the RT state is “chance RT” and “high probability RT” in a general game.

  The role lottery table associates random values (0 to 65535) that can be generated by the random number generator 112 with the lottery results, and the random number determination unit 414 uses the random number extracted by the random number extraction unit 412 as the random number value. A lottery result (lottery result number) is derived depending on which numerical range of the combination lottery table belongs. Then, the winning combination corresponding to the derived lottery result number becomes the winning winning combination as a result of the winning lottery. However, if the lottery is associated with the derived lottery result number, it means that no winning combination has been won. A value obtained by dividing the number corresponding to each combination by 65536 is the winning probability of each combination.

  For example, in the case of the lottery table shown in FIG. 7A, if the extracted random number is a value included in the range of “0” to “41740”, the lottery result number “10” is derived, The result of the lottery will be lost. If the extracted random number is a value included in the range of “41741” to “50718”, the lottery result number “12” is derived, and the result of the winning lottery is the winning of the re-playing player a. . When a lottery result number associated with a plurality of combinations is derived, all the associated combinations are won. For example, in the combination lottery table shown in FIG. 7A, if the extracted random number is a value included in the range of “51377” to “55744”, the lottery result number “7” is derived, and the small combination 2a, small part 2b and small part 2c are elected.

  As a result of the lottery, when a certain winning combination is won, the flag corresponding to the winning combination (hereinafter referred to as a winning flag) is turned on (“1”) by the random number determination means 414. The on / off state of the winning flag corresponding to each combination is stored in the RAM 110 shown in FIG. When one game is completed, if a winning flag corresponding to either the re-playing winning combination or each small winning combination is turned on by winning determination means 430 described later, a winning combination corresponding to the winning flag is displayed. Regardless of whether or not it is established, the winning flag is turned off. On the other hand, if the winning flag of any one of the BB combination a, the BB combination b, and the RB combination is turned on during the general game, the combination is not turned off even if the game ends. The on state is maintained until is established. Thus, the state where the ON state of the winning flag is maintained is also referred to as “carrying over the bonus flag”.

  Further, in a game in which the bonus flag is carried over, if any small role or re-playing role is won in the winning lottery, the winning flag corresponding to the winning role is turned on. Therefore, the winning flag corresponding to each winning combination at this time is the ON state corresponding to the winning combination in the winning combination lottery and the special winning combination in which the ON state is held. Furthermore, in a game in which the bonus flag is carried over, when any special combination is won, the winning flag corresponding to the special combination is not turned on. Therefore, the plurality of winning flags corresponding to the special combination are not turned on in parallel.

  Next, in the combination lottery tables shown in FIGS. 7B and 7C, the BB combination and the RB combination are not associated with each lottery result number. Therefore, during the RB game, the SRB game, and the BB game (more specifically, the general game during the BB), the BB combination or the RB combination is not won. Further, as shown in FIG. 7 (b), during the RB and SRB games, the combined winning probability of the small roles 1, 2a and 3 is very high at about 1 / 1.01. It can be said that the game state is advantageous for the player during the game. Furthermore, in the general game during BB, as shown in FIG. 7C, the combined winning probability of the small roles 1, 2a to 2c, 3 is not different from that during the general game (about 1/4). The winning probability is set as high as about 1/3. For this reason, it can be said that the general game during BB is also in a gaming state advantageous to the player.

  Next, in the winning lottery table for “chance RT” and “high probability RT” shown in FIG. 8, the lottery result numbers “1” to “8” are associated with each other as shown in FIG. The type of the combination and the numerical range associated with each lottery result number are exactly the same as those of the “non-RT” combination lottery table shown in FIG. However, with regard to the re-game player, only the re-game player a can be won in the role lottery table shown in FIG. 7A. However, in the game lottery table shown in FIG. Is a content that can be won. Specifically, of the re-game players a to f (see FIG. 6), which re-game player can win simultaneously is as shown in FIG. 8B. In this figure, for each of the lottery result numbers “9” to “20”, re-playing combinations that can be won at the same time are indicated by “◯” marks. That is, when the lottery result number “9” is derived, the re-game players a, c, d are simultaneously won, and when the lottery result number “10” is derived, the re-game players a, c, e are You will be elected at the same time.

  Further, when the combination lottery table for “chance RT” and the combination lottery table for “high probability RT” are compared, the re-playing combination corresponding to each of the lottery result numbers “9” to “20” is compared. Although the types are common, the numerical range associated with each lottery number is different between the two. Here, in the numerical range associated with each of the lottery result numbers “9” to “20” shown in FIG. 8B, the numbers in parentheses are the numerical ranges in the role lottery table for “high probability RT”. The other numbers indicate those in the role lottery table for “Chance RT”. As shown in this figure, in the role lottery table for “chance RT” and the role lottery table for “high probability RT”, there is a probability that any of lottery result numbers “9” to “20” will be derived. In the role lottery table for “chance RT”, it is about 1 / 7.29, whereas in the role lottery table for “high probability RT”, it is about 1 / 1.40. In other words, when the RT state is “high probability RT” during a general game, the probability that any re-game player will win in the combination lottery is very high.

  The random number determination means 414 shown in FIG. 5 selects a role lottery table corresponding to the current game state and the RT state during the general game from the role lottery tables shown in FIG. 7 and FIG. The winning combination is determined based on the random number value extracted by the extracting means 412 and the selected combination lottery table.

<Description of reel control means>
The reel control unit 420 includes a reel stop control unit 422, and performs control related to rotation driving of the reels 40L, 40C, and 40R. That is, when the reel rotation start signal transmitted from the start switch 36 is received, the stepping motors 80L, 80C, 80R are driven via the motor drive circuit 114 to rotate the reels 40L, 40C, 40R, and the stop switches 37L, 37C. When the reel stop signal is transmitted from 37R, the reel stop control means 422 causes the reel stop control to be performed.

  When a reel stop signal is transmitted from the stop switches 37L, 37C, and 37R, the reel stop control unit 422 stops the rotation of the reel corresponding to the operated stop switch within 190 milliseconds. In other words, assuming that the steady rotation speed is 80 revolutions / minute and the number of symbols per reel is 21, the reel stop control means 422 determines at most 5 symbols from the rotational position of the reel when the stop switch is operated. During the rotation, the symbol composing the symbol combination corresponding to the winning combination in the winning lottery (hereinafter referred to as the winning symbol) is the symbol stop position where the active line crosses (hereinafter referred to as the effective line position). ), The reel is stopped when the winning symbol reaches the position of the active line. Here, the rotation position of the reel means a position in the rotation direction of the reel (for example, an absolute position with a position when the symbol of symbol number “0” is at the fixed position of the middle stage M as a reference position). In addition, when another reel is already stopped and the winning symbol of that reel is stopped at the position of any effective line, the winning symbol of the reel to be stopped is the position of that effective line. The reel is stopped after moving (turning) within the above-described range so as to stop. For example, when the winning design on the left reel 40L is stopped at the upper stage U and the stop control of the right reel 40R is performed, the winning design on the right reel 40R is set to the upper stage U (position of the effective line L2) or the lower stage L. It stops in the direction which can be stopped among (position of the effective line L5).

  On the other hand, if the winning symbol cannot be reached at the position of the effective line even if the corresponding reel is rotated by 5 symbols, an appropriately determined symbol between the 5 symbols is rotated. Stop the reel so that it is stopped. In this case, even if any combination is won in the combination lottery, the combination of symbols corresponding to the combination is not stopped and displayed along the active line, so that combination is not established. Hereinafter, such a game result is referred to as “missing”.

  Here, looking at the symbol arrangement shown in FIG. 2 on the premise of the reel stop control described above, the “bell 1” symbol and the “plum” symbol in each reel indicate the timing at which the stop switch is set according to the arrangement interval. Even if it operates, it can be stopped in any of upper stage U, middle stage M, and lower stage L. Further, the “cherry” symbols on the middle reel 40C and the right reel 40R can be stopped at any of the upper stage U, the middle stage M, and the lower stage L regardless of the timing at which the stop switch is operated. Therefore, according to the payout information shown in FIG. 6, the small combination 2a (design combination: bell-bell-bell), re-playing combination a (design combination: plum-plum-plum), re-playing combination b (design combination) : Plum-Plum-Cherry), Re-playing combination c (Pattern combination: Plum-Cherry-Cherry) and SRB combination (Pattern combination: Bell 1-Plum-Cherry) Does not cause spillage. On the other hand, for combinations other than those described above, even if the reel stop control described above is performed, the combinations include symbols that cannot be stopped at the position of the effective line depending on the operation timing of the stop switch.

  Further, when the result of the lottery is lost, the reel stop control means 422 causes the symbol combination corresponding to any combination to follow the active line regardless of the timing of operating the stop switches 37L, 37C, 37R. The reels 40L, 40C, and 40R are stopped so that they are not stopped and displayed. The reel stop control means 422 performs such reel stop control so that if a winning combination is won in the winning lottery, if the winning combination is established within a predetermined range, Each reel is stopped so that no combination other than the winning combination is established. Further, when the result of the combination lottery is lost, each reel is stopped so that no combination is established.

  In addition, as described above, when a bonus combination is carried out while the bonus flag is carried over, if a small role or re-playing role is won, the winning flag of the winning role and the special role (SRB role) being carried over Both of the winning flags (except for) are turned on, and one of these combinations can be established. In this case, the reel stop control means 422 performs reel stop control for preferentially stopping the winning symbol of the selected small role or replaying character at the position of the effective line rather than the winning symbol of the special role. For this reason, there is a possibility that the player may be able to establish a special role while carrying over the bonus flag when the player loses in the role lottery or when the winning small role cannot be won (in other words, Then, when the stop switch is operated at the reel rotation position).

  In addition, when a small combination or re-playing combination is won in the combination lottery while the bonus flag is carried over, a reel stop control that preferentially establishes the BB combination is performed, contrary to the reel stop control described above. It may be determined. In this case, the reel stop control means 422 sets the winning symbol of the small role or replaying role to the position of the effective line only when it is operated at a timing at which the winning symbol of the BB symbol cannot be stopped at the position of the effective line. Reel stop control is performed to stop.

  Further, the reel stop control means 422 is determined in advance according to the operation order of the stop switches 37L, 37C, and 37R when a plurality of small combinations 2 are won or a plurality of re-playing combinations are won in the combination lottery. The reel stop control is performed so that only one combination wins. Here, FIG. 9 shows the correspondence between the types of the small combinations 2 for which the reel stop control is performed to win a prize and the operation order of the stop switches 37L, 37C, and 37R when a plurality of small combinations 2 are simultaneously won in the combination lottery. Show. Further, FIG. 10 shows the correspondence between the types of re-game players whose reel stop control is performed to be established when a plurality of re-game players are won simultaneously, and the operation order of the stop switches 37L, 37C, 37R.

  In FIG. 9, the numbers in the “lottery result number” column indicate the lottery result numbers during the general game (see FIG. 7A and FIG. 8A), and the numbers in parentheses are the lottery results during the BB general game. The numbers are shown (see FIG. 7C). Further, in this figure, the “first stop operation” refers to a stop switch operation that is first performed after the reels 40L, 40C, and 40R start rotating in one game. As shown in FIG. 9, when the lottery result number “5” is derived by the lottery during the general game, if the first stop operation is the left stop switch 37L (that is, the operation order is left → middle → In the case of right or left → right → middle), the reel stop control means 422 controls the reel stop so that the symbol combination (bell-bell-bell) corresponding to the small role 2a is stopped and displayed along the active line. I do. On the other hand, when the first stop operation is the middle stop switch 37C or the right stop switch 37R, the symbol combination (bell 2-white 7-bell 2) corresponding to the small role 2b is stopped and displayed along the active line. The reel stop control is performed as described.

  That is, when the lottery result number “5” is derived by the lottery during the general game, if the player first operates the left stop switch 37L, the small role 2a can be reliably won, but the middle stop When the switch 37C or the right stop switch 37R is operated, there is a possibility that the small part 2b may be missed unless each stop switch is operated at an appropriate timing.

  Similarly, when the lottery result number “6” is derived in the role lottery during the general game, if the first stop operation is the middle stop switch 37C (that is, the operation order is middle → left → right or middle as a result) → Right → Left), the reel stop control means 422 performs reel stop control so that the symbol combination corresponding to the small combination 2a is stopped and displayed along the active line. On the other hand, when the first stop operation is the left stop switch 37L or the right stop switch 37R, the symbol combination (bell 2-bell 2-white 7) corresponding to the small role 2c is stopped and displayed along the active line. The reel stop control is performed as described. Therefore, when the first stop operation is the left stop switch 37L or the right stop switch 37R, there is a possibility of missing the small combination 2c.

Further, when the lottery result number “7” is derived by the role lottery during the general game, if the first stop operation is the right stop switch 37R (that is, the operation order is right → left → middle or right → middle as a result) (If left), the reel stop control means 422 performs reel stop control so that the symbol combination corresponding to the small combination 2a is stopped and displayed along the active line. On the other hand, if the first stop operation is the left stop switch 37L, the reel stop control is performed so that the symbol combination corresponding to the small role 2b is stopped and displayed along the active line, and the middle stop switch 37C is used. In such a case, the reel stop control is performed so that the symbol combination corresponding to the small combination 2c is stopped and displayed along the active line. Therefore, when the first stop operation is the left stop switch 37L or the middle stop switch 37R, there is a possibility of missing the small combination 2b or the small combination 2c.
The same applies to the case where the lottery result numbers “3” to “5” are derived in the general game during BB.

Next, referring to FIG. 10, when the RT state is “chance RT” or “high probability RT” in the general game, the operation of the stop switch when a plurality of re-game players are won at the same time in the role lottery. The correspondence between the order and the type of re-game player to be established will be described.
In the following, operating each stop switch in the order of left stop switch 37L → middle stop switch 37C → right stop switch 37R is the operation sequence 1, and each stop switch in the order of left stop switch 37L → right stop switch 37R → middle stop switch 37C. Operating sequence 2, operating each stop switch in the order of middle stop switch 37C → left stop switch 37L → right stop switch 37R, operating sequence 3, middle stop switch 37C → right stop switch 37R → left stop switch Each stop switch is operated in order of 37L, operation order 4, right stop switch 37R → left stop switch 37L → middle stop switch 37C, each stop switch is operated in order of operation 5, right stop switch 37R → middle-stop switch 37C → that the operation sequence 6 to operate the stop switch in the order of the left stop switch 37L.

  First, as shown in FIG. 10A, the reel stop control means 422, when any of the lottery result numbers “9” to “14” is derived in the winning lottery, each stop switch is operated in a predetermined operation order. When operated, the reel stop control is performed so that the re-game player a is established. When operated in an operation order other than the predetermined operation order, the reel stop control is performed so that the re-game player c is established. . In this case, the “predetermined operation order” includes the operation order 1 when the lottery result number “9” is derived, the operation order 2 when the lottery result number “10” is derived, and the lottery result number “11”. If derived, operation order 3; if lottery result number “12” is derived, operation order 4; if lottery result number “13” is derived, operation order 5 and lottery result number “14” are derived. In this case, the operation order is 6.

As shown in FIG. 10B, when any of the lottery result numbers “9” to “14” is derived in the role lottery, the reel stop control unit 422 indicates that each stop switch has a predetermined operation order. The reel stop control is performed so that the re-game player b is established, and the reel stop control is performed so that the re-game player c is established when operated in an operation order other than the predetermined operation order. Do. In this case, the “predetermined operation order” includes the operation order 1 when the lottery result number “15” is derived, the operation order 2 when the lottery result number “16” is derived, and the lottery result number “17”. If derived, operation order 3; if lottery result number “18” is derived, operation order 4; if lottery result number “19” is derived, operation order 5; lottery result number “20” is derived. In this case, the operation order is 6.
Note that, as described above, the re-game players a, b, and c are associated with symbol combinations that do not miss out.

<Description of winning determination means>
The winning determination means 430 has a gaming state transition means 432, and when all of the reels 40L, 40C, 40R are stopped, it makes a winning determination for determining whether or not any combination has been established, and the gaming state transition means 432 The game state transition control described above is performed according to the result of the winning determination. The winning determination means 430 stores a type code corresponding to the symbol number of each reel shown in FIG. 2, and the nine symbol types displayed on the display window 22 when the reels 40L, 40C, 40R are stopped. Is identified. Then, based on the specified nine symbols, each symbol combination stopped and displayed along each of the effective lines L1 to L5 is recognized, and whether or not any combination is established based on the payout information shown in FIG. Determine whether. In addition, after the determination, the winning flag corresponding to the small combination or replaying combination that is turned on is turned off, and when the special combination is established, the winning flag corresponding to the special combination is turned off.

  The game state transition means 432 controls the transition of the game state (“general game”, “RB game”, “BB game”, “SRB game”) according to the establishment of the special role and the completion condition of the special game. To do. Further, during the general game, the transition of the RT state (“non-RT”, “chance RT”, “high probability RT”) is controlled according to the missing of the small combination 2 and the type of the re-playing combination established. Here, with reference to the state transition diagram shown in FIG. 11, the transition of each gaming state and the RT state will be described. First, the game state at the beginning of the game is “general game”, and the RT state is “non-RT”. In this state, if the small role 2 is missed (that is, even if any of the lottery result numbers “5” to “7” is derived), none of the small roles 2 can be won. ), The game state transition means 432 shifts the RT state to “chance RT”. In addition, when the RT state is “chance RT”, the gaming state transition means 432 shifts the RT state to “non-RT” when the re-game player c is established, and the re-game player a is established. Sometimes the RT state is shifted to “high probability RT”. Further, when the RT state is “high probability RT” and the re-playing combination c is established, the RT state is shifted to “non-RT”.

  When a BB combination or an RB combination is established during a general game, the game state is changed from “general game” to “BB game” or “RB game” depending on the established combination regardless of the contents of the RT state. Transition. When the end condition for the BB game or the RB game is satisfied, the game state is shifted to “general game”. Further, when the SRB combination is established in the general game during BB, the game state is changed from “BB game” to “SRB game”, and when the SRB game end condition is satisfied, the game state is changed from “SRB game” to “BB”. Move to "Game". Further, when the BB game end condition is satisfied during the SRB game, the game state is shifted to “general game”.

<Explanation of winning process means>
The winning processing means 440 drives a hopper (not shown) provided inside the slot machine 10 when the winning determination means 430 determines that any of the small combinations has been established. Control for paying out the corresponding number of medals (see FIG. 6) is performed.

≪Description of sub control circuit≫
The sub-control circuit 200 mainly includes an effect control unit 510, a right lottery table storage unit 520, a random number generation unit 530, a probability state storage unit 540, an operation order determination unit 550, a right lottery unit 560, and a right storage. A means 570, an advantageous game executing means 580, and a continuous lottery means 590 are included.

<Description of production control means>
The effect control means 510 includes effect data storage means 512 and effect lottery means 514, and controls the effects executed by the notification means 600. The effect data storage means 512 stores image (moving image or still image) data, sound effects or musical sound data, and blink pattern data of the upper effect lamp 72 for executing various effects. The effect lottery means 514 determines the content of the effect to be executed by lottery according to the result of the role lottery transmitted from the main control circuit 100. Thereby, the effect control means 510 performs various kinds of data (video or still image) data, sound effect or musical sound data corresponding to the effect contents determined by the effect lottery means 514, data indicating the blink pattern of the upper effect lamp 72, and the like. Data is read from the effect data storage means 510, and the image display device 70, the speakers 64L and 64R, and the upper effect lamp 72 of the notification means 600 are driven based on the various data read.

<Explanation of right lottery table storage means>
The right lottery table storage means 520 is realized by the ROM 208 shown in FIG. 4, and stores a lottery table for lottery of whether or not to generate the right to execute the ART game. Here, the ART game means that when one of the lottery result numbers “5” to “7” is derived in the role lottery when the RT state is “high probability RT”, the small role 2a wins a prize. The type of the stop switch (see FIG. 9) to be operated for the first stop is a game that is notified to the player. This ART game corresponds to an “advantageous game”. Hereinafter, the right to execute an ART game is referred to as “stock”.

  Here, with reference to FIG. 12, the contents of the lottery table stored in the right lottery table storage means 520 (hereinafter referred to as a stock generation / mode shift lottery table) will be described. The stock generation / mode transition lottery table can be determined by one lottery to determine whether to generate stock or whether to shift the current sub-mode to another sub-mode. ing. In the right lottery table storage means 520, a lottery table group consisting of a plurality of stock generation / mode transition lottery tables respectively associated with a plurality of predetermined sub-modes is stored in a plurality of predetermined roles. It is stored in association with each lottery result.

In the present embodiment, as shown in FIGS. 12A to 12F, as a result of the role lottery associated with the plurality of types of lottery table groups described above, a lost game or any of the re-game players is present. Winning (hereinafter referred to as “losing, re-playing role”), small role 1 winning (hereinafter referred to as “small role 1”), any small role 2 winning (hereinafter referred to as “small role 2”), small Role 3 is elected (hereinafter referred to as “small role 3”), RB role is elected (hereinafter referred to as “RB role”), and BB role a or BB role b is elected (hereinafter referred to as “BB role”). In addition, the sub-mode represents the likelihood of occurrence of stock and corresponds to the “selection probability state”, and is “low accuracy”, “normal”, “high accuracy”, “super high accuracy”. There are four types of submodes. In addition, the stock generation / mode transition lottery table associated with each sub-mode includes “non-winning”, loop levels “1” to “8” associated with the generated stock, “Low accuracy”, “normal”, “high accuracy”, and “ultra high accuracy” indicating the sub-mode of the transfer destination are defined. Here, the value of the loop level corresponds to the right occurrence state designation information, and the probability that the ART game will continue when the termination condition of the ART game executed by the stock is satisfied (hereinafter referred to as the continuation probability). It corresponds to). As shown in FIG. 13A, the continuation probability corresponding to each loop level value is approximately 0.0015% for loop levels “1” to “4”, 50% for loop level “5”, and loop level “ 6 ”is approximately 66.67%, loop level“ 7 ”is 80%, and loop level“ 8 ”is approximately 88.89%. In addition, “non-winning” is a lottery target item in which no stock is generated and no sub-mode shift occurs.

  The stock occurrence / mode transition lottery table is a table in which a predetermined numerical range is appropriately assigned to each lottery item described above. However, in the stock generation / mode transition lottery table shown in FIG. 12, the numerical range for each lottery target item is indicated by a numerical value (the width of the numerical range). The numerical range assigned to each lottery target item is obtained by dividing a numerical range of random numbers (an integer from 0 to 16383) generated by random number generation means 530 described later into a plurality of numerical ranges, and is assigned to each lottery target item. The numerical ranges that are produced do not overlap. For example, a numerical range of 100 to 199 is assigned to a lottery target item, and a numerical range of 180 to 300 (in this case, the numerical values of 180 to 199 overlap) is assigned to a different lottery target item. There is no. Further, the same numerical range is not assigned to a plurality of lottery target items. As a result, there is always only one lottery item to be drawn by the stock generation / mode transition lottery table, and both the generation of stock and the transition to the sub-mode are not performed simultaneously in one lottery.

  Here, looking at each stock generation / mode transition lottery table shown in FIG. 12 from the viewpoint of stock generation, each loop level “1” is obtained except for the lottery table group in which the result of the role lottery is “losing, re-playing role”. Since the total value of the numbers assigned to “8” shows a tendency that the sub-mode increases in the order of “low accuracy”, “normal”, “high accuracy”, and “super high accuracy”. “Highly accurate” has the highest probability of occurrence of stock, and hereinafter, the probability of occurrence of stock decreases in the order of “highly accurate”, “normal”, and “lowly accurate”. On the other hand, in the lottery table group in which the result of the lottery is “losing, re-playing part”, since the number is “0” in any sub-mode, no stock is generated.

  In each stock occurrence / mode transition lottery table, the larger the loop level value (the higher the continuation probability), the smaller the assigned numerical value (the narrower the numerical range), and the higher the continuation probability. The tendency is that the associated stock is less likely to occur. Furthermore, the total number of numbers assigned to the loop level of each stock occurrence / mode transition lottery table is larger as it corresponds to a role with a lower winning probability in the role lottery, and a stock with a higher continuation probability is selected. It tends to be done. For this reason, for example, it is more likely that stock will be generated when winning a small role 1 or a small role 3 than when winning a small role 2 in a role lottery, and a higher continuation probability It can be said that stocks associated with are likely to occur.

  Next, looking at each stock occurrence / mode transition lottery table shown in FIG. 12 from the viewpoint of sub-mode transition, it corresponds to each sub-mode, except for the lottery table group whose result lottery is “losing, re-gamer” The stock generation / mode transition lottery table is set so that the tendency to shift to a sub-mode with a higher probability of stock generation than the current sub-mode is stronger. However, when the submode is “ultra-high accuracy”, there is no submode with a higher probability of stock generation, so it is necessary to maintain the current submode or shift to a submode with a lower probability of stock generation. Absent. On the other hand, each stock generation / mode transition lottery table in the lottery table group in which the result of the role lottery is “losing, replaying role” tends to shift to a sub mode with a lower probability of stock generation than the current sub mode. It becomes.

  In the right lottery table storage means 520, when the game state is “general game” and the ART game is not being performed, the stop switch for the first stop operation is the middle stop switch 37C or the right stop switch. In the case of 37R, a stock generation / mode transition lottery table that is referred to regardless of the current sub-mode is stored. The contents of this lottery table are shown in FIG. As shown in this figure, in the stock generation / mode transition lottery table, since the number corresponding to each loop level is “0”, there is no possibility of stock generation, and the probability of stock generation is There is a possibility of shifting to “low probability”, which is the lowest submode. The stock generation / mode transition lottery table shown in FIG. 14 corresponds to the low selection probability state transition lottery table, and is hereinafter referred to as a penalty stock generation / mode transition lottery table.

  Here, in the stock generation / mode transition lottery table shown in FIG. 12, the loop level (that is, the continuation probability of the ART game) is set as the lottery target. Instead, the number of stocks to be generated is set as the lottery target. Good. That is, in each stock generation / mode transition lottery table shown in FIG. 12, instead of the loop levels “1” to “8”, the generation levels “1” to “8” are set as the lottery target items for each generation level. Thus, as shown in FIG. 13B, the number of generated stocks is associated. Thereby, for example, when the generation levels “1” to “4” are selected, no stock is generated, and when “5” is selected, one stock is generated. When “7” and “8” are selected, two, three, and four stocks are generated, respectively. In addition, for the stock generated in this case, an attribute called a continuation probability may or may not be given.

<Description of random number generator>
The random number generation means 530 continues the ART game based on the first random number used in the stock generation / mode transition lottery performed with reference to the stock generation / mode transition lottery table described above and the continuation probability described above. And a second random number used in the continuous lottery to determine whether or not. Here, the first random number is any integer in the numerical range of 0 to 16383, and the second random number is any integer in the numerical range of 0 to 65535.
<Explanation of probability state storage means>
The probability state storage means 520 is realized by the RAM 210 shown in FIG. 4 and stores the current sub-mode. When the sub-mode shifts in the stock generation / mode shift lottery, The mode is stored again (that is, updated).
<Description of operation order determination means>
The operation order determination means 550 is a stop switch 37L, 37C, 37R, which is a stop switch operated first by a player, a stop switch operated next, and a stop switch operated last in a game. It is judged whether it is either.

<Explanation of right lottery means>
The right lottery means 560 stores the result of the role lottery performed by the role lottery means 410 and the probability state storage means 540 among the stock occurrence / mode transition lottery tables stored in the right lottery table storage means 520. The stock generation / mode transition lottery table corresponding to the current submode is referred to, and based on the first random number generated by the random number generation means 530, it is determined whether stock generation or submode transition is possible. That is, when the value of the first random number is included in the numerical value range assigned to any one of the loop levels “1” to “8” in the stock generation / mode transition lottery table, the corresponding loop level is associated. It is assumed that the generated stock has occurred. In addition, when it is included in the numerical range assigned to any one of “low accuracy”, “normal”, “high accuracy”, and “ultra high accuracy”, it shifts to the corresponding sub mode. When the occurrence of stock is determined, the loop level is stored in the right storage means 570 described below. If the sub-mode transition destination is determined, the current sub-mode stored in the probability state storage unit 540 is updated to the transition sub-mode.

<Description of rights storage means>
The right storage means 570 is realized by the RAM 210 shown in FIG. 4, and when a stock is generated by the stock generation / mode transition lottery by the right lottery means 560, the generated stock is associated with the stock. Memorize the loop level. Further, when the stock has already been stored, and further stock is generated, the generated stock is accumulated and stored. Here, an example of a state in which a plurality of stocks are accumulated in the right lottery means 560 is shown in FIG. In this figure, the numerical value in the “stock” column indicates the order in which the stock is generated, and the loop level of the generated stock is stored in the “loop level” column. Further, when no stock is stored, the numerical value in the “loop level” column is “0”. That is, when a new stock occurs, among the values in the “stock” column, the value in the “stock” column is the smallest among the values in the “loop level” column that is “0”. A new loop level of the stock is stored in the “Loop Level” column. Therefore, in the example shown in FIG. 15A, the number of stocks accumulated is four, and the loop level of the oldest stock (hereinafter referred to as the earliest stock) is “6”, which occurs most recently. This indicates that the stock loop level is “7”.

  The ART game is executed by consuming the earliest stock, and the continuation probability of the ART game is determined by the loop level of the earliest stock. That is, when an ART game is started in the state shown in FIG. 15, an ART game having a loop level of “6” (continuation probability is approximately 66.67%) is started. When the ART game ends, the loop level of the earliest stock is deleted, and the accumulated loop level of each stock is shifted by one in the direction in which the numbers in the “stock” column become smaller. That is, when the ART game based on the earliest stock ends in the state shown in FIG. 15A, as shown in FIG. 15B, the “loop level” corresponding to the numerical value “1” in the “stock” column. The numerical value in the column is updated to the loop level “5” stored in the numerical value “2” in the “stock” column, and the numerical value in the “loop level” column corresponding to the numerical value “2” in the “stock” column is “ The value is updated to the loop level “8” stored in the numerical value “3” in the “stock” column, and the numerical value in the “loop level” column corresponding to the numerical value “3” in the “stock” column is changed to the numerical value “in” in the “stock” column. It is updated to the loop level “7” (the loop level of the most recently generated stock) stored in “4” (the most recently generated stock). Also, the value in the “loop level” column corresponding to the value “4” in the “stock” column is updated to “0”.

  Here, in the stock generation / mode transition lottery table shown in FIG. 12, the generation levels “1” to “8” (see FIG. 13B) are selected for the lottery instead of the loop levels “1” to “8”. In the case of the item, when the attribute of continuation probability is not given to the generated stock, only the number of the generated stock may be stored.

<Description of advantageous game execution means>
The advantageous game execution means 580 executes the ART game on the condition that the stock is stored in the right storage means 570. Further, the advantageous game executing means 580 executes the ART game when the game state is “general game” and the RT state is “high probability RT” as other conditions. After the ART game is started, the advantageous game execution means 580 notifies when any of the lottery result numbers “5” to “7” is derived in the role lottery while 40 games are performed. The means 600 is controlled to notify the type of stop switch of the first stop operation (see FIG. 9) for the winning combination 2a to win. This notification is information (image, message, etc.) indicating the stop switch to be notified on the display device 70, which causes the operation instruction lamp corresponding to the stop switch to be notified among the operation instruction lamps 24L, 24C, 24R to emit light. Is displayed.

  Further, when any of the lottery result numbers “9” to “14” is derived during the execution of the ART game, the advantageous game execution means 580 operates the operation sequence for establishing the re-game player a (FIG. 10 ( a) is referred to by the notification means 600. Further, when any of the lottery result numbers “15” to “20” is derived, the advantageous game executing means 580 notifies the operation order (see FIG. 10B) for establishing the re-game player b. Announce by 600. Here, the notification of the operation orders 1 to 6 described above may be performed by a known notification mode.

<Description of continuous lottery means>
The continuation lottery means 590, when 40 games have been played since the start of the ART game, again executes the ART game according to the continuation probability corresponding to the loop level of the earliest stock stored in the right storage means 570. Whether to start or not. Hereinafter, this lottery is referred to as continuous lottery. The continuation lottery means 590 makes the ART game “continue” and “do not continue” a lottery for each of the loop levels “1” to “8”, the total number is 65536, and the number of “continue” Is a continuous lottery table with the numbers shown in FIG. When the ART game is played 40 times, whether or not to continue the ART game based on the continuous lottery table corresponding to the loop level of the ART game and the second random number generated by the random number generation means 530 is determined. Lottery.

  Here, in the stock generation / mode transition lottery table shown in FIG. 12, the generation levels “1” to “8” (see FIG. 13B) are selected for the lottery instead of the loop levels “1” to “8”. In the case of an item, if the attribute of continuation probability is not given to the generated stock, the continuation lottery means 590 can be omitted. As a result, when the aforementioned advantageous game execution means 580 consumes one stock and starts an ART game, when the game is executed 40 times, the ART game is finished without being continued.

[Description of control processing in main control circuit]
≪Description of main routine≫
First, a description will be given of the control process of the main routine executed by the CPU 106 of the main control circuit 100 with reference to the flowchart of FIG. This main routine shows a control process when a game is performed in which one step from when a player inserts a game medium until the reels 40L, 40C, 40R are rotated and stopped is performed once.

  When the slot machine 10 is turned on, the CPU 106 performs a predetermined self-check and sets various flags and initial values of control data stored in the RAM 110 (step S10). Next, the CPU 106 determines whether or not the re-game establishment flag stored in the RAM 110 is turned on (step S12). This re-game establishment flag is turned on in step S202 of the RT transition processing subroutine shown in FIG. 22 described later when a re-game player is established in the previous game. When determining that the re-game establishment flag is off (NO), the CPU 106 determines whether or not a bet operation signal transmitted by operating the bet switch 34 or 35 has been received (step S14). When determining that the bet operation signal has been received (YES), the CPU 106 determines whether or not the number of medals corresponding to the operated bet switch has been credited (step S16).

  If the value of the number of credits stored in the RAM 110 is less than the value of the number of medals corresponding to the operated bet switch (hereinafter referred to as the number of inserted coins), it is determined that there are no credited medals (NO). The process returns to step S14 again. On the other hand, if the value of the number of credits stored in the RAM 110 is equal to or greater than the value of the inserted number, it is determined in step S16 that there is a credited medal (YES). In this case, the CPU 106 subtracts the inserted number value from the credit number value stored in the RAM 110 (step S18). Then, the CPU 106 adds the value of the inserted number to the value of the bet number stored in the RAM 110, and according to the value of the bet number after the addition, the bet number display lamps 26a, 26b, 26c shown in FIG. The lighting state of is updated (step S20). Next, the CPU 106 determines whether or not the value of the bet number stored in the RAM 110 has reached the specified number (three) (step S22), and determines that the specified number has not been reached (NO) Returning to step S14, if it is determined that it has been reached (YES), it is determined whether or not the start switch 36 has been operated by the player (step S28).

  On the other hand, if it is determined in step S14 that a bet operation signal has not been received (NO), the CPU 106 determines whether or not a medal has been inserted from the medal insertion slot 32 (step S24). That is, when a medal is detected by the medal sensor installed in the medal insertion slot 32, it is determined that a medal has been inserted (YES), the process proceeds to step S20, and the number of bets stored in the RAM 110 is determined. Add “1” to the value. In step S22, it is determined whether or not the number of inserted medals has reached a specified number. In contrast, if no medal is detected by the medal sensor in step S24, it is determined that no medal has been inserted (NO), and the process returns to step S14.

  If it is determined in step S12 described above that the re-game establishment flag is on (YES), the CPU 106 turns off the re-game establishment flag (step S26), and then proceeds to step S28. It is determined whether or not the start switch 36 has been operated. As a result, in the next game in which the re-game role is established, it is possible to play the game again without newly inserting medals or consuming the credited medals. Further, as the number of bets in the re-game, the number of bets placed in the previous game stored in the RAM 110 is used.

  In step S <b> 28, the CPU 106 determines whether a reel rotation start signal has been received from the start switch 36. If it is determined that the reel rotation start signal has not been received and the start switch 36 has not been operated by the player (NO), the determination in step S28 is performed again. Until the reel rotation start signal is received, the CPU 106 repeats the process of step S28. If a medal is inserted from the medal insertion slot 32 during this period, the number of inserted medals may be added to the value of the number of credits stored in the RAM 110. If the CPU 106 receives the reel rotation start signal in step S28 and determines that the start switch 36 has been operated by the player (YES), the combination lottery processing subroutine shown in FIG. 17 is executed (step S30). As a result of executing the subroutine, when any winning combination is won, the winning flag of the winning combination is turned on among the winning flags corresponding to each combination stored in the RAM 110.

  Next, the CPU 106 executes a reel variation / stop subroutine for controlling the movement of the reels to be stopped after rotating the reels 40L, 40C, 40R based on the result of lottery drawing obtained by the process of step S30. (Step S32). Details of the reel fluctuation / stop subroutine will be described later with reference to the flowchart of FIG. When all the reels 40L, 40C, and 40R are stopped by executing the reel fluctuation and stop subroutine in step S32, the CPU 106 next determines whether or not any combination has been established, and the gaming state is determined according to the determination result. And the winning determination process subroutine which performs the transition process of RT state is performed (step S34). Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, after executing the winning determination processing subroutine in step S34, the CPU 106 performs a payout process (step S36) for paying out the number of medals corresponding to the small winning combination. This payout process corresponds to the process performed by the winning processing means 440 shown in FIG. 5, and it is possible to actually pay out medals from the medal payout outlet 60, and the number of medals to be paid out is stored in the RAM 110. It is also possible to add credit to the stored number of credits. One game is completed by the above control process, and the CPU 106 returns to the process of step S12 again. Thus, by repeating the control process shown in the main routine, the player can continue to play the game.

<Description of role lottery processing subroutine>
Next, the combination lottery processing subroutine performed in step S30 of the main routine will be described in detail with reference to the flowchart shown in FIG.

  First, the CPU 106 refers to the current gaming state stored in the RAM 110, and determines whether or not the current gaming state is a BB game (step S40). If it is determined that the current gaming state is BB gaming (YES), the winning lottery table shown in FIG. 7C is selected from the winning lottery tables stored in the ROM 108 (step S42). On the other hand, when determining that the current gaming state is not BB gaming (NO), the CPU 106 determines whether or not the current gaming state is RB gaming or SRB gaming (step S44). When it is determined that the current gaming state is RB gaming or SRB gaming (YES), the winning lottery table shown in FIG. 7B is selected from the winning lottery tables stored in the ROM 108 (step) S46). In step S44, if the CPU 106 determines that the current gaming state is not an RB game or an SRB game (NO), the current gaming state is regarded as a general game, and the current RT state stored in the RAM 110 is determined. A combination lottery table (see FIG. 7A and FIG. 8) corresponding to (“non-RT”, “chance RT” or “high probability RT”) is selected from the ROM 108 (step S48).

  When the combination lottery table is selected by the processing of steps S40 to S48 described above, the CPU 106 acquires a random number generated by the random number generator 112 and has won any combination in comparison with the selected combination lottery table, or Then, it is determined whether or not it has been lost (step S50). That is, the acquired random number is sequentially compared with each winning numerical range of the winning lottery table, and a lottery result number corresponding to the numerical range including the acquired random number is derived as a result of the winning lottery. The processing in step S50 corresponds to the random number extraction unit 412 and the random number determination unit 414 shown in FIG.

  Next, the CPU 106 turns on the winning flag of the combination corresponding to the lottery result number derived by the combination lottery. Note that the ON / OFF state of the winning flag corresponding to each combination is stored in a predetermined storage area of the RAM 110. First, the CPU 106 determines whether or not any of the small roles 1, small roles 2a to 2c, and small roles 3 has been won from the derived lottery result number (step S52). If it is determined that any small combination has been won (YES), the CPU 106 turns on the state of the winning flag corresponding to the selected small combination stored in the RAM 110 (step S54). Further, when a plurality of small roles 2 are won at the same time, the relationship between the type of the stop switch that has been first stopped and the type of the small role 2 to be awarded according to the types of the plurality of small roles 2 that have been won simultaneously. (See FIG. 9) is recognized (step S56).

  If it is determined in step S52 that no small combination has been won (NO), it is next determined whether any re-game combination has been won (step S58). If it is determined that any of the re-playing combinations has been won (YES), the CPU 106 turns on a re-playing winning flag corresponding to the selected re-playing combination (step S60). Furthermore, in the case where a plurality of re-game players are won at the same time, the relationship between the type of the stop switch operated for the first stop and the type of the re-game player to be established according to the types of the plurality of re-game players won simultaneously. (See FIG. 10) is recognized (step S62).

  In step S58, when it is determined that no re-playing combination has been won (NO), the winning flag corresponding to the BB combination a, BB combination b and RB combination stored in the RAM 110 is turned on next. It is determined whether or not the bonus flag is being carried over (step S64). When determining that the bonus flag has not been carried over (NO), the CPU 106 determines whether the BB combination a or the BB combination b has been won (step S66). If it is determined that BB combination a or BB combination b has been won (YES), the state of the winning flag corresponding to the selected BB combination is turned on (step S68). On the other hand, when it is determined that no BB combination has been won (NO), the CPU 106 determines whether the RB combination or the SRB combination has been won (step S70). If it is determined that the RB combination or SRB combination is won (YES), the state of the winning flag corresponding to the winning combination is turned on (step S72).

  When the winning flag corresponding to the winning combination is turned on as a result of the winning lottery by the above processing, the CPU 106 stores the lottery result number derived in the winning lottery in the RAM 110 (step S74). If it is determined in step S64 described above that the bonus flag is being carried over (YES), the process of step S74 is performed as it is. Thus, even if the BB combination a, BB combination b or RB combination is won in the combination lottery while the bonus flag is carried over, the winning flag is not turned on. If it is determined in step S70 described above that the RB combination or SRB combination is not won (NO), the result of the combination lottery is regarded as lost, and the process proceeds to step S74 as it is.

  Next, the CPU 106 transmits role lottery information including the derived lottery result number to the sub-control circuit 200 (step S76), ends the role lottery processing subroutine, and performs step S32 of the main routine shown in FIG. Proceed to processing.

<Explanation of reel fluctuation / stop subroutine>
In the main routine shown in FIG. 16, when the above-mentioned combination lottery processing subroutine (step S30) is completed, the CPU 106 next performs a reel variation / stop subroutine (step S32). The reel fluctuation / stop subroutine will be described in detail below with reference to the flowchart shown in FIG.

  First, the CPU 106 recognizes the on / off state of the winning flag of each combination stored in the RAM 110 (step S80). Then, it is determined whether or not a predetermined shortest time (for example, 4.1 seconds) has elapsed since the reels 40L, 40C, and 40R started rotating in the previous game (step S82). If it is determined that the shortest time has not elapsed (NO), the determination process in step S82 is repeatedly executed. In other words, until the minimum time has elapsed, the reel rotation that is the next step is not started, so that the number of medals consumed in a game played within a certain time does not exceed a predetermined number. Control is in progress. If it is determined that the shortest time has elapsed (YES), the CPU 106 sequentially outputs drive pulses to the motor drive circuit 114, drives the stepping motors 80L, 80C, and 80R, and rotates the reels 40L, 40C, 40R all at once. (Step S84).

  Next, the CPU 106 determines whether or not all the reels 40L, 40C, and 40R have reached the steady rotation speed (step S86). When it is determined that the reel rotation speed has not reached the steady rotation speed (NO), the determination process of step S86 is repeated. Thus, until the reel rotation speed reaches the steady rotation speed, even if the player operates the stop switches 37L, 37C, 37R, the reel stop control is not performed. If the CPU 106 determines that the rotation speeds of all the reels have reached the steady rotation speed (YES), it determines whether or not a reel stop signal has been received from the stop switches 37L, 37C, and 37R (step). S88). This reel stop signal is transmitted from each of the stop switches 37L, 37C, and 37R when the player performs a push operation. If it is determined that the reel stop signal has been received (YES), the CPU 106 transmits information indicating the stop switch that has transmitted the reel stop signal among the stop switches 37L, 37C, and 37R to the sub-control circuit 200 (step S90). ).

  Next, the CPU 106 performs symbol combination control based on the ON / OFF state of the winning flag of each winning recognized in step S80 so that the winning combination corresponding to the winning flag in the ON state is established (step ST S92). This symbol combination control is the same as the reel stop control performed by the reel stop control means 422 shown in FIG. When a plurality of small combinations 2 or re-playing combinations are won, the symbol combination control is performed so that the combination established in accordance with the operation sequence of the stop switch recognized in step S56 or S62 in FIG.

  When the reel corresponding to the stop switch that has transmitted the reel stop signal is stopped by the process of step S92, the CPU 106 determines whether or not all the reels have been stopped (step S94). If it is determined that all the reels are not stopped (NO), the process returns to step S88, and the symbol combination control according to the result of the lottery is performed again according to the reel stop signal. If it is determined in step S88 that a reel stop signal has not been received (NO), the process proceeds directly to step S94 to determine whether all reels have been stopped. As described above, the processes in steps S88 to S94 are repeated until all the reels are stopped. When the CPU 106 determines that all the reels are stopped (YES) in step S94, the CPU 106 performs the reel variation and stop processing. The process ends, and the process proceeds to step S34 of the main routine shown in FIG.

<Description of the winning determination processing subroutine>
In the main routine of FIG. 16, when the reel fluctuation / stop subroutine (step S32) is completed, the CPU 106 then executes a winning determination process subroutine (step S34). Hereinafter, a detailed description will be given using the flowchart of the winning determination processing subroutine shown in FIG.

  First, the CPU 106 recognizes nine types of symbols stopped and displayed on the display window 22 (step S100). Then, the CPU 106 refers to information indicating the current gaming state stored in the RAM 110, and determines whether or not the current gaming state is “RB gaming” (step S102). When determining that the RB game is being played (YES), the CPU 106 subtracts “1” from the value of GCNT stored in the RAM 110 (step S104). This GCNT is a variable for counting the number of games played during the RB game, and the initial value “12” is set in step S176 of FIG.

  Next, the CPU 106 determines whether or not any of the small combinations 1, small combinations 2a to 2c, and small combinations 3 has won a prize based on the nine symbols recognized in step S100 (step S106). If the CPU 106 determines that any small role has won (YES), the payout number of medals corresponding to the winning small role is read from the payout information shown in FIG. Is updated to the value of the read payout number (step S108). Here, the value of the payout number count indicates the number of medals to be paid out to the player by the payout process in step S36 of FIG. Next, the CPU 106 subtracts “1” from the value of WCNT stored in the RAM 110 (step S110). This WCNT is a variable for counting the number of times that a small combination has won during the RB game, and the initial value “8” is set in step S176 of FIG. On the other hand, when it is determined in step S106 that none of the small roles has been won (NO), the above-mentioned payout number count value is cleared (that is, the value is set to “0”) (step S112).

  When the processing of step S110 or S112 is performed, the CPU 106 determines whether or not the RB game end condition is satisfied. That is, it is determined whether or not the value of either GCNT or WCNT has become “0” (step S114). If the value of either GCNT or WCNT is “0” (YES), it is considered that the RB game end condition is satisfied, and the current game state stored in the RAM 110 is “RB game”. Is updated to “general game” (step S116). Further, the CPU 106 updates the current RT state stored in the RAM 110 to “non-RT” (step S118). Next, the CPU 106 turns off only the winning flags of all the small combinations and replaying combinations stored in the RAM 110 (step S120). That is, in the process of step S120, the winning flags for the BB combination a, the BB combination b, the RB combination, and the SRB combination are not turned off.

  Next, the CPU 106 transmits the game result information of the current game and the current game state information to the sub-control circuit 200 (step S122). Here, the game result information is information indicating the type of winning combination. The game state information is information indicating the current game state and RT state. Then, when the game result information and the game state information are transmitted to the sub control circuit 200 by the process of step S122, the CPU 106 ends the winning determination process shown in FIG. 19, and proceeds to the process of step S36 shown in FIG. move on.

  In step S102 described above, when the CPU 106 determines that the current gaming state is not “RB gaming” (NO), next, whether or not the current gaming state is “BB gaming” or “SRB gaming”. Is determined (step S124). When it is determined that the current gaming state is “BB gaming” or “SRB gaming” (YES), the CPU 106 performs a BB gaming process which will be described in detail below (step S126). On the other hand, when it is determined that the current game state is neither “BB game” nor “SRB game” (NO), the CPU 106 regards the current game state as “general game”. Then, a general game process which will be described in detail later is performed (step S128). Then, when the process of step S126 or S128 is completed, the process proceeds to the above-described step S120, and only the winning flags of all the small combinations and replaying combinations stored in the RAM 110 are turned off. Thereafter, the CPU 106 proceeds to step S122, transmits the game result information of the current game and the current game state information to the sub-control circuit 200, and ends the winning determination process shown in FIG.

<Description of processing subroutine during BB game>
Next, the contents of the BB gaming process subroutine executed in step S126 of the winning determination process subroutine shown in FIG. 19 will be described using the flowchart shown in FIG.

  First, the CPU 106 determines whether or not the current gaming state stored in the RAM 110 is “SRB gaming” (step S130). When determining that the SRB game is being played (YES), the CPU 106 subtracts “1” from the value of GCNT stored in the RAM 110 (step S132). This GCNT is a variable for counting the number of games played during the SRB game, and the initial value “12” is set in step S160 described later.

  Next, the CPU 106 determines whether or not any of the small combinations 1, small combinations 2a to 2c and small combinations 3 has won a prize based on the nine symbols recognized in step S100 in FIG. 19 (step S134). If the CPU 106 determines that any small combination has won (YES), the payout number of medals corresponding to the winning small combination is read from the payout information shown in FIG. Is updated to the value of the read payout number (step S136). Next, the CPU 106 adds the payout number of medals corresponding to the above-mentioned winning small combination to the value of the BB payout number count stored in the RAM 110 (step S138). Here, the BB payout number count is for counting the total number of medals paid out during the BB game. When the BB payout number count exceeds 200, the CPU 106 It is determined that the end condition is satisfied.

  Next, the CPU 106 subtracts “1” from the value of WCNT stored in the RAM 110 (step S140). This WCNT is a variable for counting the number of times a small combination has won during the SRB game, and the initial value “8” is set in step S160 described later. On the other hand, if it is determined in step S134 that none of the small roles has been won (NO), the above-mentioned payout number count value is cleared (that is, the value is set to “0”) (step S142). When the process of step S140 or S142 is performed, the CPU 106 determines whether or not the SRB game end condition is satisfied. That is, it is determined whether or not the value of either GCNT or WCNT has become “0” (step S144). If the value of either GCNT or WCNT is “0” (YES), it is considered that the SRB game end condition is satisfied, and the current game state stored in the RAM 110 is “SRB game”. Is updated to “BB game” (step S146).

  Next, the CPU 106 refers to the value of the BB payout count stored in the RAM 110, and determines whether or not the value exceeds 200 (step S148). When the CPU 106 determines that the number exceeds 200 (YES), it is considered that the BB game end condition is satisfied, and the current game state stored in the RAM 110 is updated from “BB game” to “general game”. (Step S150). Then, the CPU 106 updates the current RT state stored in the RAM 110 to “non-RT” (step S152), ends the BB gaming process shown in FIG. 20, and proceeds to the process of step S120 in FIG. Transition. On the other hand, if the CPU 106 determines in step S148 that the BB payout count value does not exceed 200 (NO), it is considered that the BB game end condition is not satisfied, and the BB shown in FIG. The in-game process is terminated, and the process proceeds to step S120 in FIG.

  If the CPU 106 determines that the current gaming state is not “SRB gaming” (NO) in step S130 described above, is the SRB combination established based on the nine symbols recognized in step S100 of FIG. It is determined whether or not (step S154). When determining that the SRB combination is established (YES), the CPU 106 turns off the winning flag corresponding to the SRB combination stored in the RAM 110 (step S156), and updates the current game state to “SRB game” (step S156). Step S158). Next, the CPU 106 sets the GCNT value stored in the RAM 110 to “12”, sets the WCNT value to “8” (step S160), and clears the payout number count value to “0”. (Step S162). Then, the process proceeds to step S148 described above, and it is determined whether or not the BB game end condition is satisfied. If the BB game end condition is satisfied, the processing of steps S150 and S152 is performed, and then the BB game is performed. The middle processing subroutine is terminated, and the process proceeds to step S120 in FIG.

  In addition, in the process of step S154 described above, when the CPU 106 determines that the SRB combination is not established (NO), any of the small combinations 1, small combinations 2a to 2c, and small combinations 3 won next. Whether or not (step S164). If it is determined that any small combination has been established (YES), the CPU 106 reads out the number of medals to be paid out corresponding to the winning small combination from the payout information shown in FIG. The count value is updated to the value of the read payout number (step S166). Then, the CPU 106 adds the value of the number of payouts updated in step S166 to the value of the payout count in BB stored in the RAM 110 (step S168), and then proceeds to the above-described step S148 to finish the BB game end condition If the BB game end condition is satisfied, the processing in steps S150 and S152 is performed, and then the BB game in-process subroutine is terminated, and the process proceeds to step S120 in FIG. .

<Description of general game processing subroutine>
Next, the contents of the in-game processing subroutine executed in step S128 of the winning determination subroutine shown in FIG. 19 will be described using the flowchart shown in FIG. First, the CPU 106 determines whether or not an RB combination has been established based on the nine symbols recognized in step S100 of FIG. 19 (step S170). If the RB combination has been established (YES), the CPU 106 updates the winning flag corresponding to the RB combination stored in the RAM 110 from on to off (step S172), and changes the current gaming state to “ The game is updated from “general game” to “RB game” (step S174). Next, the CPU 106 sets the value of the variable GCNT stored in the RAM 110 to “12” and the value of the variable WCNT to “8” (step S176). The CPU 106 clears the payout number count value to “0” (step S178), ends the general game processing subroutine, and proceeds to step S120 in FIG.

  If the CPU 106 determines in step S170 described above that the RB combination is not established (NO), then the CPU 106 determines whether or not the BB combination a or BB combination b is established (step S180). If it is determined that the BB combination a or the BB combination b is established (YES), the CPU 106 updates the state of the winning flag of the BB combination that is turned off (step S182), and sets the current gaming state to “ After updating from “general game” to “BB game” (step S184), the value of the BB payout count stored in the RAM 110 is cleared to “0” (step S186). Then, the process proceeds to step S178 described above, and after the value of the payout number count is cleared to “0”, the in-game processing subroutine is terminated, and the process proceeds to step S120 in FIG.

  If the CPU 106 determines in step S180 described above that neither the BB combination a nor the BB combination b is established (NO), RT transition processing described in detail below is performed (step S188). When the RT transition process ends, the CPU 106 ends the general game processing subroutine as it is, and proceeds to step S120 in FIG.

<Explanation of RT transfer processing subroutine>
Next, the contents of the RT transition processing subroutine executed in step S188 of the general gaming processing subroutine shown in FIG. 21 will be described using the flowchart shown in FIG. First, the CPU 106 determines whether or not any re-game player has been established based on the nine symbols recognized in step S100 of FIG. 19 (step S200). Then, when any of the re-games is established (YES), the CPU 106 turns on the state of the re-game establishment flag stored in the RAM 110 (step S202). Next, the CPU 106 determines whether or not the current RT state stored in the RAM 110 is “chance RT” (step S204). When the current RT state is “chance RT” (YES), the CPU 106 determines whether or not the established re-gamer is the re-game game a (step S206), and the re-game game a is established. If (YES), the current RT state is updated to “high probability RT” (step S208). Then, the CPU 106 clears the payout number count value stored in the RAM 110 (step S210), and ends the RT transition process.

  If the CPU 106 determines in step S204 described above that the current RT state is not “chance RT” (NO), then the CPU 106 determines whether or not the current RT state is “high probability RT” (step S212). . When the current RT state is “high probability RT” (YES), the CPU 106 determines whether or not the established re-gamer is the re-game game c (step S214), and the re-game game c is established. If yes (YES), the current RT state is updated to “non-RT” (step S216). Then, the CPU 106 proceeds to the process of step S210, clears the payout number count value stored in the RAM 110, and ends the RT transition process. On the other hand, when the CPU 106 determines in step S214 that the re-playing role c is not established (NO), and in step S212, the current RT state is determined not to be “high probability RT” (NO). In any case, the process proceeds to step S210 as it is to clear the payout number count value, and the RT transition process is terminated.

  Further, when the CPU 106 determines in step S206 described above that the re-gamer a is not established (NO), the process proceeds to step S214, and it is determined whether or not the re-gamer c is established. If the re-game player c is established, the current RT state is updated to “non-RT” in step S216, and if not established, the process immediately proceeds to step S210, and the payout number count value is set. After clearing, the RT transfer process is terminated.

  Next, in step S200 described above, if the CPU 106 determines that no replaying combination has been established (NO), whether any of the small combination 1, the small combination 2a to 2c, or the small combination 3 has won a prize. It is determined whether or not (step S218). If it is determined that any small combination has been established (YES), the CPU 106 reads out the number of medals to be paid out corresponding to the winning small combination from the payout information shown in FIG. The count value is updated to the read payout number value (step S220), and the RT transition process is terminated as it is.

  On the other hand, if the CPU 106 determines in step S218 that none of the small roles has been won and the game result has been lost (NO), the CPU 106 next stores the current RT stored in the RAM 110. It is determined whether or not the state is “non-RT” (step S222). If the current RT state is “non-RT” (YES), it is next determined whether or not the lottery result number derived in the role lottery is any of “5” to “7”. (Step S224). If the derived lottery result number is any of “5” to “7” (YES), the CPU 106 considers that the small role 2b or the small role 2c has been missed, and the current RT state is “chance RT”. (Step S226).

  Then, the process proceeds to step S210, the value of the payout number count stored in the RAM 110 is cleared, and the RT transition process is terminated. On the other hand, when the CPU 106 determines in step S222 described above that the current RT state is not “non-RT” (NO), or in step S224, the derived lottery result number is “5”. When it is determined that none of “˜7” (NO), the process immediately proceeds to step S210, the payout number count value stored in the RAM 110 is cleared, and the RT transition process is terminated.

[Description of control processing in sub-control circuit]
Next, various processes executed in the sub control circuit 200 will be described with reference to the flowcharts shown in FIGS. Here, FIG. 23 is a flowchart showing the contents of the ART game process executed when the main control circuit 100 receives the winning lottery information transmitted by the process of step S76 of FIG. . FIG. 24 shows the contents of the stock generation / mode transition lottery process executed when the main control circuit 100 receives the stop operation information transmitted as a result of the process of step S90 of FIG. It is a flowchart. FIG. 25 shows the contents of the ART transition continuation process executed when the main control circuit 100 receives the game result information and the game state information transmitted as a result of the process of step S122 of FIG. It is a flowchart to show.

<Description of ART game processing>
The contents of the ART game process will be described with reference to the flowchart shown in FIG.
First, the CPU 206 shown in FIG. 4 determines whether or not the role lottery information has been received from the main control circuit 100 (step S300). If the CPU 206 determines that no combination lottery information has been received (NO), the ART game process is terminated and another control process is executed. On the other hand, if it is determined that the winning lottery information has been received (YES), the CPU 206 determines whether or not the ART flag stored in the RAM 210 is on (step S302). This ART flag is a flag indicating whether or not an ART game is currently being performed. If it is on, it indicates that an ART game is in progress, and if it is off, it indicates that it is not in an ART game. When the CPU 206 determines that the ART flag is on (YES), the lottery result number derived by the winning lottery performed by the main control circuit 100 is recognized based on the received winning lottery information. (Step S304).

  Next, the CPU 206 determines whether or not the lottery result number derived in the role lottery is any of “5” to “7” (step S306). When it is determined that the lottery result number is any one of “5” to “7” (YES), the CPU 206 performs a first stop operation to win the small combination 2a according to the recognized lottery result number. A stop switch to be performed (right, middle or left, see FIG. 9) is notified to the player (step S308). Then, the ART game process is terminated and another control process is executed.

  If the CPU 206 determines in step S306 that the lottery result number derived in the role lottery is not any of “5” to “7” (NO), the lottery result derived in the role lottery is next. It is determined whether the number is any of “9” to “14” (step S310). If it is determined that the lottery result number is any one of “9” to “14” (YES), the CPU 206 determines the stop switch 37L for establishing the re-game player a according to the recognized lottery result number. The operation order of 37C and 37R (see FIG. 10A) is notified to the player (step S312). Then, the ART game process is terminated and another control process is executed.

  Furthermore, when the CPU 206 determines in step S310 that the lottery result number derived in the role lottery is not any of “9” to “14” (NO), the lottery result derived in the role lottery is next. It is determined whether the number is any one of “15” to “20” (step S314). When it is determined that the lottery result number is any one of “15” to “20” (YES), the CPU 206 determines the stop switch 37L for establishing the re-game combination b according to the recognized lottery result number. The operation order of 37C and 37R (see FIG. 10B) is notified to the player (step S316). Then, the ART game process is terminated and another control process is executed.

  By performing the above processing, when the lottery result numbers “5” to “7” are derived in the role lottery during the ART game, the type of the stop switch to be subjected to the first stop operation for winning the small role 2a is determined. Since the notification is made, the player can reliably win the small combination 2a by operating the notified stop switch first. Further, during the ART game, when the lottery result numbers “9” to “14” are derived in the role lottery, the re-game player a is replayed. When the lottery result numbers “15” to “20” are derived, the re-game is replayed. The operation order of the stop switches in which the combination b is established is notified. For this reason, if the player operates the stop switch in accordance with the notified order, the player can be surely established the re-game player a or the re-game player b. That is, when the RT state is “chance RT”, it is possible to reliably establish the re-game player a and shift to “high probability RT”. Further, since the re-game player c is not established, the current RT state (“chance RT” or “high probability RT”) can be maintained, and the transition to the “non-RT” state can be avoided.

<Description of stock generation / mode transition lottery processing>
Next, the contents of the stock generation / mode transition lottery process will be described with reference to the flowchart shown in FIG.
First, the CPU 206 determines whether stop operation information has been received from the main control circuit 100 (step S320). If the CPU 206 determines that the stop operation information has not been received (NO), the stock generation / mode transition lottery process is terminated and another control process is executed. On the other hand, when determining that the stop operation information has been received (YES), the CPU 206 determines whether or not the current gaming state stored in the RAM 210 is “general gaming” (step S322). . The RAM 210 stores the current gaming state and RT state based on the gaming state information received from the main control circuit 100. If the CPU 206 determines that the current game state is not “general game” (NO), the stock generation / mode transition lottery process is terminated and another control process is executed. On the other hand, when the CPU 206 determines that the current game state is “general game” (YES), it is determined whether or not the stop operation information received in step S320 relates to the first stop operation. A determination is made (step S324). Here, for example, when the stop operation information is received first after receiving the lottery information from the main control circuit 100, it is determined that the stop operation information is related to the first stop operation.

  If the CPU 206 determines that the stop operation information received in step S320 is not related to the first stop operation (NO), the stock generation / mode transition lottery process is terminated and another control process is executed. On the other hand, if it is determined that the first stop operation is related (YES), the CPU 206 indicates that the received stop operation information indicates that the operated stop switch is the left stop switch 37L. It is determined whether or not (step S326). If the left stop switch 37L is indicated, the CPU 206 refers to the current sub-mode stored in the RAM 210 (step S328), and the winning combination determined from the received lottery result number; A stock generation / mode transition lottery table (see FIG. 12) corresponding to the current sub-mode is selected (step S330).

  On the other hand, when the CPU 206 determines in step S326 that the received stop operation information does not indicate that it is the left stop switch 37L (NO), the ART flag stored in the RAM 210 is turned on. It is determined whether or not (step S332). If it is determined that the ART flag is on (YES), the processing of steps S328 and S330 is performed, and the stock generation / mode transition lottery corresponding to the winning combination and the current submode is performed from the ROM 208. A table is selected, but if it is determined that the ART flag is off (NO), the penalty stock generation / mode transition lottery table shown in FIG. 14 is selected from the ROM 208 (step S334).

  Next, the CPU 206 generates an integer random number (corresponding to the first random number generated by the random number generation means 530 in FIG. 5) within a numerical range of 0 to 16383, and generates the stock generation / selected in step S330 or S334. Based on the mode transition lottery table, a stock generation / mode transition lottery is performed as to whether or not stock generation or sub-mode transition is possible (step S336). Here, if the generated random number is included in the numerical range assigned to “non-winning” in the stock generation / mode transition lottery table, no stock is generated and the sub mode is not shifted. If stock is generated as a result of the stock generation / mode transition lottery, for example, as shown in FIG. 15, the loop level is stored and accumulated in such a form that the order of generation of the stock is known. If the sub-mode shift is determined, the current sub-mode stored in the RAM 210 is updated to the transfer-destination sub-mode determined by the stock generation / mode shift lottery (step S338). And if the above process is performed, CPU206 will complete | finish a stock generation / mode transfer lottery process, and will perform another control process.

  Here, in the stock generation / mode transition lottery table shown in FIG. 12, the generation levels “1” to “8” (see FIG. 13B) are selected for the lottery instead of the loop levels “1” to “8”. In the case where the attribute of the continuation probability is not given to the generated stock, the number of the generated stock is simply stored in the RAM 210. Hereinafter, the storage area of the RAM 210 that stores the number of generated stocks is referred to as a stock counter. When stock is generated by the lottery process in step S336 described above, the number of generated stock (numerical value) is added to the value of the stock counter in the RAM 210 in the process in step S338.

<Description of ART migration / continuation processing>
Next, the contents of the ART transition / continuation process will be described with reference to the flowchart shown in FIG.
First, the CPU 206 determines whether or not game result information and game state information are received from the main control circuit 100 (step S340). If the CPU 206 determines that the game result information and the game state information have not been received (NO), the ART transition / continuation process is terminated and another control process is executed. On the other hand, when it is determined that the game result information and the game state information are received (YES), the CPU 206 determines whether or not the ART flag is turned on (step S342). If the CPU 206 determines that the ART flag is on (YES), it determines whether or not the current gaming state is a special game (RB game, BB game or SRB game) (step S344). . When it is determined that the current game state is a general game (NO), the CPU 206 performs processing related to the continuation of the ART game. That is, first, the CPU 206 adds 1 to the ART value stored in the RAM 210 (step S346). This ART value indicates how many times the ART game has been played. Next, the CPU 206 determines whether or not the ART value exceeds 40 (step S348). When it is determined that the ART value does not exceed 40 (NO), the CPU 206 ends the ART transition / continuation process and performs other processes in order to continue the ART game.

  On the other hand, when it is determined that the ART value exceeds 40 (YES), the CPU 206 determines the continuation probability corresponding to the loop level of the stock that caused the current ART game (FIG. 13 (a)). )), A continuous lottery for determining whether or not to continue the ART game is performed (step S350). The CPU 206 that performs the process of step S350 corresponds to the continuous lottery means 590 shown in FIG. As the continuous lottery process in step S350, for example, in the ROM 208 shown in FIG. 4, for each of the loop levels “1” to “8”, a lottery that “continues” the ART game in the numerical range of 0 to 65535 is performed. A numerical range that is a numerical value shown in FIG. 13A is assigned to the target, and a continuous lottery table in which the remaining numerical range is assigned to the lottery target “not continue” is stored in advance. Then, when performing the process of step S350, the CPU 206 generates an integer random number (corresponding to the second random number generated by the random number generation means 530 in FIG. 5) within the numerical range of 0 to 65535, Whether to continue the ART game is determined based on the above-described continuous lottery table corresponding to the loop level.

  Next, the CPU 206 determines whether or not to continue the ART game is determined as a result of the continuous lottery performed in step S350 (step S352). If it is determined that it is determined to continue the ART game (YES), the CPU 206 sets the value of ART stored in the RAM 210 to “0” (step S360). Then, the CPU 206 ends the ART transition / continuation process and performs other processes. On the other hand, if it is determined in step S352 that it is not determined to continue the ART game (NO), the CPU 206 determines whether or not stock is stored in the RAM 210 (step S354). Here, it is assumed that the stock stored in the RAM 210 is stored in the form shown in FIG. When the stock is stored in the RAM 210 (YES), the CPU 206 updates the current loop level stored in the RAM 210 to the loop level of the stock that has been generated first (step S356).

Then, the CPU 206 updates the order of occurrence of each stock stored in the RAM 210, that is, increments by one (step S358). Then, in order to start a new ART game, the CPU 206 proceeds to step S360, sets the value of ART stored in the RAM 210 to “0”, ends the ART transition / continuation processing, and performs other processing. I do.
If the CPU 206 determines in step S354 that no stock is stored in the RAM 210 (NO), the ART flag stored in the RAM 210 is turned off to end the ART game (step S362). After clearing the current loop level stored in the RAM 210 (step S364), the ART transition / continuation processing is terminated and other processing is performed.

  Next, in step S344 described above, when the CPU 206 determines that the current gaming state is a special game (YES), that is, the ART flag is on (step S342, YES), and the current gaming state When the gaming state is a special game, it can be regarded as a state immediately after a special combination (here, RB combination, BB combination a or BB combination b) is established in one game in the slot machine 10 during the ART game. The CPU 206 proceeds to step 362 to end the ART game, turns off the ART flag, then proceeds to step S364, clears the current loop level stored in the RAM 210, and then proceeds to ART transition / continuation. The process ends.

  Next, a case where the CPU 206 determines in step S342 described above that the ART flag is off (NO) will be described. In this case, first, the CPU 206 determines whether or not the current RT state is “chance RT” (step S366). When the RT state is “chance RT” (YES), the CPU 206 determines whether or not the small role 1 has won as a result of the current game (step S368). Then, when the CPU 206 determines that the small combination 1 has won (YES), it is determined whether or not stock is stored in the RAM 210, assuming that the condition for shifting to the ART game is satisfied (step S370). When the CPU 206 determines that the stock is stored in the RAM 210 (YES), it turns on the state of the ART flag stored in the RAM 210 (step S372), performs the processing from step S356 described above, and performs the ART. Start playing.

  On the other hand, when the CPU 206 determines in step S366 that the current RT state is other than “chance RT” (step S366, NO), the current RT state is “chance RT” in step S368. If it is determined that the small role 1 has not won (step S368, NO), or if it is determined in step S370 that there is no stock (step S370, NO), the CPU 206 immediately ends the ART transition / continuation process. To do other processing.

  Here, in the stock generation / mode transition lottery table shown in FIG. 12, the generation levels “1” to “8” (see FIG. 13B) are selected for the lottery instead of the loop levels “1” to “8”. In the case where the attribute of the continuation probability is not given to the generated stock, the processes of steps S350, S352, S356, S358, and S364 shown in FIG. 25 can be omitted. That is, if the determination result in step S348 is YES, the process immediately proceeds to step S354, and it is determined whether or not the value of the stock counter in the RAM 210 is “1” or more (with stock). When the value of the stock counter is “1” or more (YES), after subtracting “1” from the value of the stock counter, the process proceeds to step S360, and the value of ART stored in the RAM 210 is set to “0”. To end the ART transition / continuation process. On the other hand, if the value of the stock counter is “0” in step S354 (NO), the process proceeds to step S362, the ART flag is turned off, and the ART transition / continuation process is terminated. In starting the ART game, if the ART flag is turned on by the process of stock S372, the value of the stock counter is decremented by "1", and then the process proceeds to step S360.

  As described above, in the present embodiment, whether or not stock generation and sub-mode transition are possible, the continuation probability of the generated stock, and the sub-mode of the transition destination are shown in the stock generation / mode transition lottery table shown in FIG. As described above, since each of these items is determined by lottery using a lottery table configured so that a plurality of items are not selected at the same time in one lottery, the generation of stock (when the stock occurs, the loop level is also selected at the same time. In other words, the sub-mode transition is not performed at the same time. For this reason, when stock is generated and its loop level is selected, it is selected under the submode that has recently shifted to the previous lottery opportunity.

  Therefore, when the loop level of the generated stock is predicted based on the current submode estimated by the player, when the ART game based on the generated stock ends in a period that does not match the predicted loop level, It can be determined that the estimated submode is likely to be incorrect. In other words, since the current submode guess can be verified with a certain degree of certainty, the act of guessing the submode is not wasted, and the player is provided with the enjoyment and utility of guessing the submode. Can do. In addition, since the various lottery items described above can be selected by one random number, the types of random numbers to be generated should be reduced compared to the case where these various items are individually lottery using separate random numbers. Can do. Therefore, when a random number is generated by arithmetic processing, the burden can be reduced.

In the present embodiment, as in a conventional slot machine, the type of winning combination in the winning lottery may be notified. By performing such notification, the stock generation / mode transition lottery table to be referred to in the stock generation / mode transition lottery is selected from the various lottery table groups shown in FIGS. It is possible to grasp more clearly which lottery table group belongs to.
In the present embodiment, the continuous lottery is performed every time the ART game is performed 40 times. However, the continuous lottery may be performed every game. In this case, the processes of steps S346 and S348 in FIG. 25 can be omitted.
In the present embodiment, the type of the stop switch of the first stop operation that the small role 2a will win is notified only during the ART game. However, regardless of the on / off state of the ART flag, BB You may perform the same alert | report also in a middle general game. In this case, for example, when the determination result in step S300 of FIG. 23 is YES, it is determined whether or not the current gaming state is “BB gaming”. If so, the process proceeds to step S304. However, if not, the process of step S302 may be performed.

  Even if the ART flag is off, if the predetermined condition is met, the current RT state is “chance RT”, and any of lottery result numbers “9” to “14” in the role lottery May be notified when the re-game player a is established. In this case, for example, in step S302, NO in FIG. 23, it is determined whether or not the predetermined condition described above is satisfied. If the predetermined condition is satisfied, the process proceeds to step S310, and the process is repeated. The operation order of the stop switch that can establish the game player a is notified. Here, the above-mentioned predetermined condition means that an ART lottery is performed when an information lottery for winning with a predetermined probability is performed, and when winning in the notification lottery or after the previous BB game or RB game ends. When a predetermined number of general games are played without being played.

  In this embodiment, if the ART flag is OFF (NO) in step S332 of FIG. 24, the process proceeds to step S334 and immediately selects the penalty stock generation / mode transition lottery table. When the determination result of step S332 is NO continuously for the predetermined number of games, the process may proceed to step S334 to select a penalty stock generation / mode transition lottery table. In this case, when the predetermined number of games has not been reached, the process shifts to the processing after step S328, and the lottery stock generation / mode shift according to the result of the current game lottery and the current sub-mode. A lottery table is selected, and at that time, a warning may be issued to the player that an inappropriate stop switch operation has been performed.

  Further, in this embodiment, the stock generation / mode transition lottery is performed when the first stop operation is performed (see FIG. 24, step S336), but is performed by the ART transition / continuation process illustrated in FIG. You may do it. In this case, first, in FIG. 24, when the CPU 206 determines in step S324 that the first stop operation has been performed (YES), the operated stop switches are the left stop switch 37L, the middle stop switch 37C, and the right stop switch. Information indicating which of the switches 37R is (hereinafter referred to as first stop operation information) is stored in the RAM 210, and the stock generation / mode transition lottery process shown in FIG. 24 is terminated.

  Also, in the ART transition / continuation process shown in FIG. 25, whether or not the current gaming state is a general game when the CPU 206 determines in step S342 that the ART flag is off (NO). If it is not a general game, the ART transition / continuation process in FIG. 25 is terminated. On the other hand, when the current gaming state is a general game, the CPU 206 refers to the first stop operation information stored in the RAM 210, and thereafter the same processing as that shown in steps S326 to S338 of FIG. Process. Then, when the process of step S338 in FIG. 24 is performed, the CPU 206 continues to perform the processes after step S366 in FIG.
